PSB has taken its over 40 years of experience in bringing real sound to real people and packed it into the exciting M4U 4 High Definition In-Ear Monitors. You're listening to music more than ever before, but now you can do it on-the-go in comfort and style with PSB's true-to-nature sound quality. The M4U 4 is the latest addition to PSB’s popular M4U Headphone Series, which features the company’s innovative RoomFeel™ Technology that has won praise throughout the world.

Good sound comes in small packages
With scientifically developed RoomFeel technology, you will be amazed that these in-ear M4U 4s allow you to experience the sound of high performance speakers in a perfect listening room wherever you go. The M4U 4 features a two-way Hybrid Dual-Driver System of dynamic and balanced armature drivers for true hi-fi listening.

The precision balanced armature driver used in the M4U 4 is individually calibrated to meet its exacting response tolerances. A wave guide is used to link the sound tube of the balanced armature driver to the woofer, creating time-aligned driver integration. A miniature PCB using surface mount parts creates the electrical crossover network that divides the signal between drivers. The moving coil dynamic woofer is tuned for accurate response with three separate chambers, resulting in smooth response and reduced resonances. You’ll enjoy deep, deep bass response that is punchy and crisp without sounding fat or boomy.

Ergonomically sound
These small and lightweight portable in-ear monitors are also designed for convenience for people on the move. The comfortable low profile ergonomic design and around-the-ear cable placement ensures that the M4U 4s stay in place for active listeners. Two fully detachable cables are included, one with a 3-button Apple remote with microphone for answering and making phone calls.

Comply Foam Tx-200 Series Eartips
High-tech, super-soft memory foam that is heat-sensitive and breathable, the Comply™ Foam Tx-200 Series Eartips conform to the dynamic shape of the ear canal. The foam's passive noise-reduction technology seals out unwanted ambient noise and pours pure music directly into your ears, without leaking bass. These eartips are extraordinarily soft and comfortable for long-term wear. Simply enjoy clear, crisp sound.

Standard silicon gel tips, a convenient carrying case, and stereo and airplane adaptors round out the M4U 4 accessories. Available in Arctic White and Black Diamond.
