About the Sennheiser HD599
Sennheiser's open-back overacheiver
This is sort of a hidden gem in Sennheiser's stellar lineup of headphones. The HD599 'phones were released to little fanfare, but I feel they deserve some love and attention. If great sound is your bag, well, that's the main focus here. Impressive bass for an open-back design, and really fine detail in the mids and highs. Their soft earpads stayed comfortable through an entire work shift at my house. (Just note that they do leak sound — I decided against wearing them at the office.)

Comfort is an often overlooked — but extremely important — factor when it comes to headphones. How your headphones fit and feel plays a big part in how much you'll enjoy them.
We tested and scored several headphones to give you a better idea about fit and wearability before you buy.

How did we test comfort?
We invited a group of 20 Crutchfield employees to try on a selection of 50 over-ear headphones and grade them on fit and comfort. See all headphones we tested.
How did we grade these headphones?
Our participants rated each set of headphones by assigning a separate score for five different fit and comfort elements, or "Fit Factors": (1) ear pad softness; (2) headband softness; (3) clamping pressure; (4) perceived weight; and (5) how secure and stable they stayed during head movement.

Featured review
These Sennheiser 599 headphones are very good. I ordered them late one day and received them the next! Great service! My only complaint is that one day after receiving them I saw them on another site for less! I have never been so disappointed with Crutchfield ??

Features
Overview: The new Sennheiser HD 5 series of headphones feature a contemporary design with a soft, padded headband and ear cups. Featuring Sennheiser's proprietary transducer technology and E.A.R. (Ergonomic Acoustic Refinement) design, the HD 5 series headphones deliver excellent sound quality from your smart device or home stereo system. The HD 599 model comes with a 10' cable with a 1/4" (6.3mm) plug for your home stereo, and a 51" cable with a 3.5mm straight plug for your portables. A 1/4"-to-3.5mm adapter is included, allowing you to use the 10' cable with a device or component with a 3.5mm headphone jack.
Note: The large diameter of the 1/4"-to-3.5mm adapter may interfere with some smartphone and tablet cases, preventing a full connection to the device.
Open Back Design: The HD 599 headphones headphones feature an open back design that lets you be a part of your listening environment. Sennheiser's E.A.R. technology directs the sound directly to your ears to give you a natural sounding listening experience, similar to listening to well-placed loudspeakers. The high-end transducers used in the HD 5 series delivers deep, satisfying bass with clean, smooth mids and highs.
Stylish: The elegant look of the HD 599 is highlighted by the matte metallic detailing on the ear cups and stylish ivory color scheme. The large soft padded detachable ear pads are covered in plush brown velour, while the wide padded headband features an elegant stitched brown leather cover.
Cable: The HD 599 comes with a high-quality 10' cable with a full-size 1/4" (6.3mm) plug, designed for plugging into your home stereo equipment. You can also use the headphones in the recording studio for mixing or monitoring live performances. A 1/4"-to-3.5mm adapter is included for the 10' cable so you can listen to your smartphone, tablet, or other device equipped with a mini-jack. The adapter has a large diameter that will likely interfere with your smartphone or tablet case, preventing you from completely inserting the plug into the device. Also included is a shorter 51" cable with a straight 3.5mm plug for listening to your devices on the go. (You will have to control your music manually on the device, as there is no in-line remote on this cable.)
