Our take on the AudioQuest JitterBug™

We're big fans of AudioQuest's award-winning DragonFly® plug-in USB DACs (digital-to-analog converters). Now AQ has developed the JitterBug, an innovative device made to enhance the performance of the DragonFly Red v1.0, DragonFly Black v1.5, or any other USB DAC. You simply plug the ultra-compact JitterBug into the USB port of any computer, DAC, receiver, streamer, NAS device, or car stereo to reduce noise and restore your music's clarity, dynamics, and warmth. You can even connect it to your smartphone.

An easy sonic upgrade for your USB DAC

We're big fans of AudioQuest's award-winning DragonFly® plug-in USB DACs (digital-to-analog converters). Now AQ has developed the JitterBug, an innovative device made to enhance the performance of the DragonFly Red v1.0, DragonFly Black v1.5, or any other USB DAC. You simply plug the ultra-compact JitterBug into the USB port of any computer, DAC, receiver, streamer, NAS device, or car stereo to reduce noise and restore your music's clarity, dynamics, and warmth. You can even connect it to your smartphone.

How does it work?

The JitterBug is a dual-function filter that cleans up noise in both the power and data portions of the USB interface. It performs like a line conditioner for the USB voltage bus, as well as acting as a signal filter for the USB data bus. In both cases it suppresses electrical noise that interferes with your DAC's sensitive circuitry. The JitterBug can reduce timing jitter as well, but it doesn't re-clock the digital audio stream to eliminate jitter.

Slightly smaller than the DragonFly, the JitterBug has a male USB plug on one end and a female USB port on the other. If you already own a DragonFly, the JitterBug is an easy, affordable upgrade. Simply plug JitterBug into any of your computer's available USB ports, then plug the DragonFly into JitterBug's USB port. If you're using a different USB DAC, you plug the JitterBug into an available USB port, and use a USB cable to connect the JitterBug to your DAC.

Crutchfield customer from Dallas, GA on 12/28/2018

Crutchfield Customer Review (What's this?)

I have been using ITunes through my IPhone to a Pioneer car audio system via USB cable.Sometimes I was getting some minor distortion on high notes.Since connecting IPhone to Jitterbug I am hearing smoother and more balanced sound.



Audioquest Quality!

AudioQuest is top quality! The JitterBug is amazing!



Nice improvement for good recordings

William from Portland, OR on 9/5/2018

Crutchfield Customer Review (What's this?)

This product is absolutely NOT snake oil! Added this and the Dragon Tail adapter to my existing Dragonfly Black and am enjoying a pleasant upgrade on all well-recorded music. Hearing more air and space in classical recordings that convey more of the venue in which the performance was recorded. Especially pleased with increased bass weight and speed when plugged into a smartphone. For sixty bucks, this is a nice improvement if you enjoy well-recorded acoustic music.

Pros: Value for price, subtle but satisfying improvement


As advertised

Richard from Delmar, NY on 8/4/2018

Crutchfield Customer Review (What's this?)

It does what it claims to do. I would recommend it for computer and NAS use. As for sound I did not notice a huge difference probably because of the headphones I used which were hi fidelity(AudioQuest ) along with the dragonfly red. I did not improvement when I was using it alone or on less expensive equipment the did have noticeable noise.

Pros: Noticeable improvement when the noise is obvious. Works as advertised and is useful when used for NAS and datapacket loss prevention m.

Cons: Price

Added a little more "air" to my 2nd gen Dragonfly. Grab one. It's a no-brainer.



AudioQuest JitterBug™

Crutchfield customer from Modesto, CA on 6/3/2018

Crutchfield Customer Review (What's this?)

The good: cleaned up some percussion artifacts and seems to add a little layering to the music plus system is cd quiet. Along with Dragonfly Black pretty much presents the music about equal to a average cd.(on Pandora) The bad: The USB dongle is not a great inspiring fit into computer port. Funny, the Dragonfly was. You can feel a lot of wiggle when you touch the combo. If the fit was better I would give 5 stars.



Seems nice, just didn't solve the problem

bruce from Bethesda, MD on 3/20/2018

Crutchfield Customer Review (What's this?)

The item is well-made and beautifully packaged. It just didn't solve my problem of low level buzz pick-up on my USB line. Neither, BTW, did installing a double ferrite trap cable. And I was just a bit disappointed that when I got an RMA to send it back, Crutchfield imnformed me that "as a service " they'd charge my account $10 for return shipping. Pretty steep, I thought, on this purchase.

Pros: s


Subtle but real improvement!

stephen from Ft Lauderdale, FL on 3/15/2018

Crutchfield Customer Review (What's this?)

This device absolutely improved the overall sound of my music streaming from my laptop. It is subtle, but noticeable. The sound is clearer, deeper and smoother. I believe I've got the best possible sound now from my Macbook. I have the Audioquest Jitterbug connected via Audioquest Forest USB to Audeze Deckard Amp/DAC to Sennheiser HD 650 Headphones listening to Tidal. Sublime Sonic Perfection.

Pros: Marked improvement in sound

Cons: None

overall; pleased

k.woods from Hixson, TN on 3/4/2018

Crutchfield Customer Review (What's this?)

i purchased this product in an attempt to clean up my usb signal because i was getting some random crackle/pop noise occasionally when my phone was playing music over my car jvc arsenal radio... in all fairness, some of the occasional "static-like-pops" still happen randomly, but it has definitely lessened the frequency in which it seems to occur ...but overall i think the playback does sound warmer & fuller... & considering all the effort ive put into this system... the time & money & research... i just figured, what-the-hey, every lil bit helps right?!? the end it did not cure my problem, but it definitely helped, & i feel it enriched my sound quality so im grateful & would purchase it again as well as recommend it to others. & i can not say enough good things about the outstanding customer service ive always gotten when dealing with the crutchfield folks. always "above & beyond" & always friendly & willing to help. in this day & time, sad to say that their level of customer care is rare. keep it up yall, & well keep coming back & sendings folks ur way. thanx & god bless ya!

Pros: easy to hook up. does what it says it does. file it under the "every-lil-bit-helps" catagory

Cons: n/a

Best/cheapest Upgrade for Your System

David from Norfolk, VA on 2/27/2018

Crutchfield Customer Review (What's this?)

I could hear an audible difference in the quality of the sound once I plugged this little guy in. I wasn't really aware what I was missing. I read some reviews and decided to give it a try. I figured that for the price it was worth the risk. I was pleasantly surprised and I would recommend this product without reservation.

Pros: Affordable, easy to use, works well

Cons: It is a bit "fat" and so may prevent you from using a neighboring USB port

Crutchfield Customer Review (What's this?)

excellent for eliminating noise in streaming signals



Improvement varies with digital material and equipment

Charlie from Colonia, NJ on 12/30/2017

Crutchfield Customer Review (What's this?)

It works. Clarity is better. However, improvements are far less noticeable if the recording is bad. Also, Much of pop and contemporary music today is mixed in a studio resulting in sound stages that are closer to being two dimensional and this is more evident. Remember - it Does not improve the signal - just cleans it up. I have the Jitterbug connected to the IPAD via camera adaptor with an AudioQuest Carbon on the other end into the Deckard headphone DAC/Amp. Live recordings in high res formats benefit the most. Works great in the car too.

Pros: Good value

Cons: None

Solid product

Adam from Okc ok on 6/19/2017

Crutchfield Customer Review (What's this?)

Using this inline between phone and Helix processor. Nothing ground breaking, but for the price it was worth a try. Probably works great for computer audio.

Pros: Cheap and effective

Cons: None that I can think of

I Wanted to Hear Improvement

Crutchfield customer from Pawtucket, RI on 4/26/2017

Crutchfield Customer Review (What's this?)

I wanted to like this very much. I have interconnects and speaker cable that I love. I've heard the difference in various materials making an audible difference in the sound we perceive using an a/b comparison. I use solid silver core interconnects over inexpensive "copper" interconnects. Yes, there is an audible difference. There is even an audible difference between silver-plate and solid silver. Silver plate sounds more 'strident' than solid silver; at least for me. Okay. But what about the Jitterbug? I've been using it for a few weeks(allowing for some burn-in, if that was necessary) and I have heard no audible change in my audio. Nothing. I was using a standard data usb cable for my asynchronous dac and it sounded awful. I swapped out the data usb for a solid silver cable and the audible improvement was astounding. I added the Jitterbug to the chain and heard no more improvement. None. Took the Jitterbug out, no change. In or out of the chain there was no audible improvement. I don't know about the experience of others but I didn't enjoy the same experience. Your mileage may vary.

Pros: Small, Not too expensive

Cons: Made no audible difference

More Natural Sound In The Car

Tim from Simpsonville, SC on 12/13/2016

Crutchfield Customer Review (What's this?)

Bought a Jitterbug for use in my new Kenwood Excelon DDX9903S car stereo, placed between the head unit and my USB drive. Upon replacing the factory Bose/Clarion unit with the Excelon, there was more detail, deeper bass and extended high frequencies. Unfortunately there was also some digital harshness and glare which really became apparent after extended listening. This wasn't simply high frequency brightness. The Jitterbug really helped to tame the digital harshness and glare. Now the system sounds very good and much more natural. It still has the detail, bass and high frequencies, but without the glare, and is much more enjoyable for long periods of listening.

Pros: Improved Sound Quality, Value


All-around noticeable improvement

Kerwin from Brooklyn, NY on 11/27/2016

Crutchfield Customer Review (What's this?)

I wasn't sure what to expect with this little device. Like others, I read customer and professional reviews and decided to give it a try. Considering the price there was little risk involved. After doing a good amount of A/B testing with hi-res tracks I know very well, I can definitely hear it when the JitterBug isn't in the chain (connected to my Apogee Groove). There is no one aspect of the sound that it seems to improve over others. It seems to give everything a little bit more polish or refinement. Soundstage is a little deeper and wider. The stereo separation is a little more apparent. There's a tad more clarity in the high-end. There were also more mid-range details in some tracks that I didn't notice before. Installation was easy enough, but depending on how your USB ports are arranged, you might lose access to the port directly above/below/left/right of the JitterBug. For my set up, I needed to get a short USB extender to relieve stress on the port.

Pros: Easy installation; No drivers required;

Cons: Bulky; Depending on the configuration of your USB ports, horizontally/vertically adjacent ports may be blocked by the JitterBug; Might strain port;

Jitter free

james f from Maryland on 9/7/2016

Crutchfield Customer Review (What's this?)

After some apprehension on this product I decided to purchase this device solely on there reputation and I'm glad I did. I cannot say I hear a difference in audio reproduction but there is no glitchyness in playing from my iPod in my car. Smooth and clear. For the price I'm happy with my purchase and will continually use this product

Pros: Price and versatility of hardware

Cons: Size, even though it is small when used with a USB cable it does stick out a bit


Roger from Jamaica Plain, MA on 6/25/2016

Crutchfield Customer Review (What's this?)

Definitely hear the difference, connected to Dragonfly with Audeze EL8 headphones. Music has more presence, depth, and richness. It's not a game changer, but a substantial improvement for not much money. Sort of like going up $100-200 in headphone quality. Worth it if you listen to music at your computer a lot.

Pros: sound quality, inexpensive

Cons: nope

Noticeable if not marginal improvement...

Erik from Honolulu, HI on 4/2/2016

Crutchfield Customer Review (What's this?)

Audioquest makes a bunch of high quality stuff. This is no exception. I run this along with their dragonfly dac...with only the dragonfly the music was good, but when adding the jitterbug things noticeably "tightened up" a bit. It isn't gonna do miracles and change mediocre signal or source or cheap equipment, nor would i imagine it doing too much to a perfect system, but for $50 this thing definitely made a difference for me and i found it both noticeable and worthwhile.

Pros: noticeable cleaner tighter sound, inexpensive

Cons: none. if you have realistic expectations

It Work's!

FlyFish77 from Wheeling IL on 3/28/2016

Crutchfield Customer Review (What's this?)

I plugged the Jitterbug in between my computer and the USB cable connected to my DAC. Magically the sound coming out of my stereo sounded better. I will probably get another one to see if plugging another Jitterbug into an empty USB slot ups the sound even more. I have tried expensive USB cables that have made no difference in sound. Great bang for the buck.

Pros: Cheap as audio additions go. Simple to use.

Cons: None in my system.

The Jitterbug works

Mr Mic from Peoria Az on 2/16/2016

Crutchfield Customer Review (What's this?)

Crazy-- how does this little thing at such a great price work it's magic ? I bought a new car and surprise--- no CD player but a USB input instead. Loaded a ton of music onto a flash drive and decided to ignore a lesser sound quality than I usually demand. The Jitterbug addition has made it all sound warmer, smoother and more musical. Even bass lines articulate better, rather than just vibrate, and horn sections like T.O.P. have gotten less bright and grating. I'm a believer !

Pros: Small crazy inexpensive upgrade....

Cons: Probably need to buy a couple more !

JitterBoom or JitterBust?

Chet from Media, PA on 2/13/2016

Crutchfield Customer Review (What's this?)

When I first heard about the JitterBug, I was a skeptic. Could this little gadget really make a difference and improve the audio from my laptop's usb output? I read enough positive reviews to be convinced that it was worth a try. I'm happy to report that in my set-up it does make a noticable, positive improvement in sound quality. My audio chain consists of an Acer laptop running foobar 2000 through the JitterBug to a Fiio X3ii DAC and on to a Schiit Magni 2 headphone amp. My headphones are the Sennheiser HD 650. All my files are lossless CD rips or hi-res Flac downloads. What I noticed right away was greater control and punch in the bass and lower frequencies. This made familiar tracks sound more dynamic to me. Overall clarity was very good. I have read that the JitterBug will not make a difference in a high end system. I can not speak to this assertion. What I can say is that for me, it provided a cost effective tweak to my mid-fi set-up.

Pros: Sound quality improvement, plug and play

Cons: None

Installation Consideration

Grimp from Easton, MD on 2/8/2016

Crutchfield Customer Review (What's this?)

A Low Pass USB filter is what I gather this is. Limiting a USB 3.0 port to USB 2.0 speed for strictly USB 2.0 devices is OK with me. I can't say I hear any improvement, but at least it works. I might add that this is a asymmetrically fat device that may only fit on one end of a string of side by side USB outputs, so don't buy 2 without considering space

Pros: I like the idea, apparently no harm. I generally like/trust AudioQuest products.

Cons: Fat (width), I think user improvement depends on my external variables.

I'm keeping it

Dave from Alabama on 2/7/2016

Crutchfield Customer Review (What's this?)

I'm not actually sure how to rate this product as I changed speakers before I installed it but I believe it has made an improvement. One other thing, I had to get an active usb hub for my computer to recognize it. The FAQ's about this products states that sometimes that may be the case with some DAC's.




Frank from columbus, OH on 2/5/2016

Crutchfield Customer Review (What's this?)

Inexpensive upgrade that does what it says it does. Using it with the original Dragonfly DAC for listening to music from my Macbook. Lowers the noise floor. Can hear more of the music's inner detail and less digital sounding. I'm using standard Apple lossless. I would imagine the effect would be even greater with high resolution files.

Pros: Great value. Nice upgrade for the price. Easy to use.

Cons: None

Awesome Product

Dunamis from kapolei, HI on 1/24/2016

Crutchfield Customer Review (What's this?)

At first I thought I couldn't hear a difference and I was going to return it and consider it snake oil. I was using it with the standard iPhone & iPad lightning connections. I decided to order the AudioQuest lighting connectors, one Carbon & one Cinnamon. WOW! There is a huge difference in the warmth of sound. I have since ordered a total of four, one for home receiver, office computer, the car and home computer. All sound much better with the Jitter Bug installed. It smooths out the sound and adds extra warmth to my music.

Pros: It Really Works!!!

Cons: None

Problem Solver

Mike from Georgia on 11/28/2015

Crutchfield Customer Review (What's this?)

I listen to dsd, 24 bit flac and flac files ripped from cds. The bug corrected the problem with the cd files, they are now very smooth on the top end. That was never a problem with the hi res files. I transfer music from my computer through the bug to my micro sd card and use the card in different systems.

Pros: reduces listener fatigue

Cons: none

Well worth it!

John from Pennsylvania on 11/18/2015

Crutchfield Customer Review (What's this?)

This product is well worth the investment. I incorporate a Dragonfly Dac V1.2, an Audioquest Golden Gate audio interconnect with Audioengine A5+ computer speakers, which provide a nice combination. However, when I added two Jitterbugs into the USB ports of my MacBook Pro, I noticed a definite improvement as my digital music now sounds more analog. I hope this helps.

Pros: More of an analog sound.

Cons: None.

Audioquest Jitterbug use

Bill R. from California on 10/27/2015

Crutchfield Customer Review (What's this?)

I like using the jitterbug in a spare usb port, rather than inline to my DAC. The improvement is small but well worth the price. The Jitterbug is convenient to use, and will last many years.

Pros: Convenient, and works to improve sound and picture quality.

Cons: Audiophiles with high end cables and components may or may not get an improvement using the jitterbug inline. But then they have the option of using it in another port.

Smooth Operator

minicooper6 from Virginia on 10/25/2015

Crutchfield Customer Review (What's this?)

I am using the AudioQuest JitterBug between my Apple Macbook Pro and a McIntosh D150 DAC. Honestly, I was a bit skeptical about hearing any sonic improvement but was pleasantly surprised at the positive results in the sound quality. I listen to a lot of jazz, blues and vocalists and the changes, while not huge, were definitely audible and pleasing. It's kind of hard to describe what I'm hearing but I'd put it as being a bit more tight, quiet and focused. Equipment: McIntosh c2300, McIntosh MC452, McIntosh D150, McIntosh MCT450, B&W 801 Series II, OPPO-105D, VPI Prime w/ Dynavector 20x2

Pros: Cost, Ease of use, It works

Cons: I wish the end of the JitterBug was slightly tapered as it does catch on the lid of my MacBook Pro when closed (WITH) its Speck case.


Guest from HAMDEN, CT on 10/19/2015

Not immediately obvious, but after several "with and without" comparisons I would say there is a difference for the better.

Pros: cost/benefit

Cons: none

If you use digital files, get it

cw from Hawaii on 10/7/2015

Crutchfield Customer Review (What's this?)

If digital files are an important source in your listening habits, you ned to get at least one of these. Designed to be inserted between the file data and DAC to filter garbage, they were effective and improved sound quality when inserted in any unused port. When used with Apple's lightning to female USB connector, they made MP3 music from iPads and iPhones sound smoother and more open. The price is right and Crutchfield ships free. Audioquest is also excellent in answering any questions about the jitterbug and its uses.

Pros: ease of use - just plug it in sounds great affordable fast, free shipment

Cons: should be packaged two in a box to save on cardboard Audioquest should offer an adapter for lightning ports since Apple charges so much for theirs


Jankeis from Massachusetts on 10/7/2015

Crutchfield Customer Review (What's this?)

I wanted this to be a device that clearly improved the sonic quality of the music I stream via USB from my computer to my Oppo 105D. Hey $50 bucks. But I did not appreciate any improvement. It didn't deteriorate the sound. I spend a lot of time tweaking my class A system but this didn't impact my system.

Pros: Simple to install on your system

Cons: No appreciable improvement.

Crutchfield customer from Georgia on 9/8/2015

Very surprised at the improvement. Not earth shattering, but definitely discernable after plugging it in. Hopefully it will break in with more improvement. Equipment: Accoustic Zen Adagio's, Accoustic Zen Matrix interconnects and Accoustic Zen Sartori speaker cables. Vincent MK236 into Centrance DAC. Source Apple Mac Mini with Pure Music software.

Pros: Easy Installation

Cons: none

Small wonder

DJV from Massachusetts on 9/7/2015

Crutchfield Customer Review (What's this?)

I was delighted to hear this little USB miracle. I have had a different brand and it was just a fancy aluminum adaptor. BUT this one works! The soundstage was wider, vocals smoother, and slow musical passages dead quite. Worth every penny. As a matter of fact, I bought more than 1 of these. I plan to buy a couple more as well, for additional equipment. Buy one, or several! Crutchfield also was one of the first to have these. Another plus from a great company.

Pros: Wider soundstage, smoother vocals, dead quite background!

Cons: Nothing

Outstanding Value

Ira C from Middletown, CT on 9/7/2015

Crutchfield Customer Review (What's this?)

This is the best value in electronics today. It works as advertised and made an instant improvement when listening to music files or ripped CD's via my laptop. If you would like more depth, better imagining, and a clearer audio experience, I suggest you give the JitterBug a try.

Pros: Works great and costs very little. Crutchfield service is excellent.

Cons: Had to wait until more came into stock.

AudioQuest JitterBug

Jay S from Wisconsin on 8/30/2015

Crutchfield Customer Review (What's this?)

First I would like to say to save you time in today's busy world in reading a longer review than what you have time for, I have been using the JitterBug for two weeks now and just ordered two more! That about sums up what I think. Now some detail. I am using this with my iPad and a iFi iDSD DAC Amp portable setup and Sennheiser 650. and 600's Headphones. It gives me more detail, definition and separation, or think of it as adding some space-air between instruments and vocals with removing some edge on the attack and tail of the notes. Makes it easer to listen over long periods of time. Note: I believe if it were used like with a Boombox type of output equipment, you would not hear much of a difference. Likewise if used with the best of hi end DAC's-amps, I believe that they are already addressing the issues that the AudioQuest JitterBug is helping to improve. Although I can not verify that state-meant because I only have a iFi iDSD DAC Amp and a OPPO 105 to compare with, which I love. I have also ordered the UpTone Audio USB REGEN to work with my portable setup and my Main System. A Mac. mini server 2013, Amarra Symphony, Amarra, Amarra SQ, Amarra SQ+ and Amarra for Tidal. I stream this to an OPPO-105 and use the balanced outs to a Krell HTS Home Theater Standard preamp-processor. I am using the oppo's DAC's and the Krell's HTS great preamp out with Nordust Quantrafill balanced Cables to a pair of Krell 450 mono block amps to a pair of Thiel reference 7.2 speakers.

Pros: Only about $50.00 -- it really helps!

Cons: It does not fix everything, but it certainly helps. Need adaptor to plug in closer to the iFi iDSD.

Dance to the music

REShaman from New York on 8/26/2015

Crutchfield Customer Review (What's this?)

As a member of an audio related website, I am a computer audio enthusiast. Do I qualify as an audiophile? Do not regard myself that way. Rather as one who enjoys music. You may imagine that I have invested time and money into a synergy that delivers the highest quality of SQ (sound quality). Please understand the following: I can not review the AudioQuest JitterBug without acknowledging other components in the synergy of components that conspire to deliver such high quality SQ. So given that I also employ a system that includes other audio components, the difference is exceptional. Thank you for the most innovative components other than software players of distinction that address other criteria that contribute overall to the finest SQ. Bravo to those innovators, and the AudioQuest JitterBug as I employ them (two with a third on order -- another story) is worth the price of admission (smile). Highly recommended based on my results with my system. I can not account for what others experience, only my experience

Pros: Performance.

Cons: None that I can think of.


Hands-on research

Product Research


USB Data & Power Noise Filter: The Audioquest JitterBug is designed to remove unwanted noise currents and parasitic resonances from both the data (communication) and Vbus (power) lines of USB ports. JitterBug meets all USB 2.0 speed specifications. JitterBug's excellent performance is the result of careful design and craftsmanship, comprehensive technical measurements, and thorough listening tests. As a result the JitterBug improves dynamic contrast, warmth and resolution of your audio.

Dual Discrete Noise-Dissipation Circuits: JitterBug's dual-circuitry works on both the data (communication) and vbus (power) lines of USB ports. The latter reduces noise and prevents EMI and RFI from contaminating the associated digital-to-analog converter (DAC) and/or cable. The former minimizes parasitic resonances created by the computer and USB bus, and is optimized to remove noise above the USB 2.0 frequency specification, making it ideal for audio playback.

Note: When used with USB 3.0 devices, the JitterBug purposely decelerates the device to USB 2.0 specifications.

Jitter Reduction: The JitterBug also measurably reduces jitter and packet errors (in some cases, packet errors are completely eliminated). The result is a clearer and more compelling sound and overall better audio experience.

USB 2.0 Connectors: The JitterBug features a female USB 2.0 (type-A) port on one end and a male USB 2.0 (type-A) connector on the other end.

Applications: JitterBug is extremely easy to use and will offer reliable results for many years to come. It can be used with external USB digital-to-analog converters (DACs), mobile phones and portable media devices, and network streaming/storage devices. Use the Audioquest JitterBug in the following applications.

  • Use one JitterBug in line with any computer and USB DAC (digital-to-analog converter).

Optional DragonFly: Audioquest's DragonFly (703DGNFLY2, sold separately) is a digital-audio converter and headphone amplifier with an onboard 64-step analog volume control. It has a USB plug at one end and a 3.5mm minijack at the opposite end. It connects to any Mac or Windows PC and bypasses the computer's compromised audio circuitry to deliver cleaner, clearer, more naturally detailed sound to headphones, powered desktop speakers, or complete audio systems. Insert JitterBug the in series with DragonFly to further reduce noise and resonances.
