Hear PSB's refined sound, everywhere you go
The PSB M4U 4 in-ear headphones (exploded view, pictured in white) use dynamic and balanced armature drivers for true-to-life sound that's tuned to sound like PSB speakers.
PSB is best known for their for their highly regarded speakers, which have a reputation for producing accurate, precise sound. Here at Crutchfield, we often use a set of PSB towers as reference speakers when testing out new home audio equipment. With the M4U 4 in-ear headphones, they've used a hybrid dual-driver technology called RoomFeel™ to re-create their stellar "listening room" experience in a compact, go-anywhere design.
Each earbud has a two-way crossover system and two types of drivers. A balanced armature driver delivers highs and mids with the kind of clarity worthy of PSB loudspeakers. At the same time, a dynamic driver produces bass so tight and deep, you can practically picture a pulsing woofer in front of you.
Find your fit and seal out sound leaks
So you can enjoy the M4U's natural sound comfortably, PSB includes six pairs of replaceable ear tips — three sizes of silicon gel tips and three sizes of Comply™ memory foam tips. The special foam tips are not only super-soft and breathable, but they also conform to your ear canal and create a tight seal. This helps stop ambient noise from making its way into your listening session, and keeps your music from leaking out.
Two detachable cables for listening at home or on the go
The PSB M4U 4 in-ear 'phones include two separate cables. There's a standard straight cable for listening at home or at your desk. When you're out and about, the other cable wraps around your ear, keeping the ear pieces sturdy and secure. This mobile cable also includes a three-button remote that gives you convenient iPhone® control. There's even a built-in mic for making and taking calls.

Overview: The PSB M4U 4 high definition in-ear monitors are part of the Music for You (M4U) series of high performance headphones. The M4U 4s come with two detachable cables, cable management clip, airline and 1/4" adapters, 6 pairs of ear tips, and a semi-hard zippered storage case.
Hybrid Dual Drivers: The M4U 4 in-ear monitors feature a unique two-way Hybrid Dual-Driver design with a moving coil dynamic driver to handle the low frequencies and a low-mass balanced armature driver for the highs. A precision crossover network controls the frequencies, routing them to the appropriate drivers. The drivers and crossover are housed in a multi-chamber, vented ABS enclosure. This two-way design helps implement PSB's innovative RoomFeel technology, making the headphones sound as true-to-nature as a pair of loudspeakers in a typical listening room.
Ear Tips: The M4U 4 comes with a two types of ear tips, each in small, medium, and large sizes. The Comply Foam Tx-200 ear tips are made of soft, high-tech memory foam. The body heat-sensitive tips can be compressed to fit into your ear canal and expand to form an air-tight seal. This passive noise reduction seals out unwanted ambient noise and enhances the bass response. An integrated wax guard keeps ear wax from entering the sound port, which diminishes the sound quality. Also included are three pairs of silicon gel ear tips.
Cables: The M4U 4 includes two interchangeable, tangle-free cables. One cable (55" in length) has an in-line remote and microphone with a call answer button, microphone, and music playback controls for iPod, iPhone, and iPad. The other cable (48") has no remote or microphone. The package include a snap-on 3.5mm-to-1/4" adapter, airline adapter, and a cable management clip.
