For at-home or on-the-go listening, these passive mode headphones are designed to give you the experience of Room Feel, but without all the fuss. Just put them on and enjoy. No batteries or switches necessary. Just pure simple sound. Like all PSB designs, the M4U 1 model emphasizes true-to-nature sound that doesn't take anything away from the musical performance.
The latest M4U addition is the M4U 1 Over-Ear Headphone, which offers our Room Feel™ technology and the same musicality of our award-winning M4U 2 Active Noise Cancelling Headphones, but without amplification or noise cancelling. The M4U 1 brings the precise true-to-nature sound of PSB's in-room loudspeakers to affordable personal listening.
Listen longer in extra comfort. The ergonomic ear pads are gyro-suspended and self-adjusting to give you a precise fit, and naturally isolate your music from the outside world. The light weight and extremely soft replaceable ear pads allow you to lose yourself in those extended listening sessions. The expandable headband also adjusts easily for a more customized fit.
On a train, on a plane, from your computer to your bedroom, PSB headphones are lightweight and ready to pack up anywhere you want to go. Fold 'em up into the protective travel case and you'll never be far from true hi-fi listening. We even added a thoughtful touch for your comfort—dual input connections on either side of the headphones means no more crossed wires. Just plug in the cable on the left or right and be within easy reach of a headphone jack no matter where it's situated.
Two tangle—free cords are included—one standard and the other featuring an in-line remote to play, pause, or skip music, as well as a microphone to take calls from iPhone® or Blackberry®. Other accessories include a protective travel case, extra ear pads, microfibre cleaning cloth, ¼" (6mm) stereo adaptor, and dual input flight adaptor.
