PSB Speakers gets up close and personal with your hi-fi. We've taken our 40 years of bringing real sound to real people and packed it into our exciting new Music for You (M4U) series of high performance headphones. You're listening to music more than ever before, but now you can do it in comfort and style with PSB's true-to-nature sound quality. 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.
