Conclusion: PSB M4U 2 is a superb example of a premium headphone that does almost everything right. The headset provided good noise cancellation, a rich and brilliantly detailed sonic signature, and an impressive feature set, all bundled into one of the most comfortable pair of cans we’ve put on.
Summary: Had these for just over 2 months now and have a couple hundred hours with them. These are a very balanced headphone in terms of the frequency range they are capable of. Paul Barton (the man who designs PSB speakers) suggests this is 20-20,000 Hz @ ± 1.5 Hz, and I believe him.
Summary: Just got my PSB M4U 2 headphones after a dilligent search for the right cans for my lifestyle. I am a "limited audiophile". Limited since my main genre is classic rock from the 60's and 70's. If you need a broader range of music style to consider, then please press on.
Summary: Bought this PSB M4U2 for a few days now,, super happy and excited - bought it from a headphone store. ( Headphone Bar - w. boardway, Vancouver bc )
I always wanted a noise cancelling headphone with passive mode and uses batteries than stupid rechargeable ones..
Pros: Very detailed and well balance + good enough punchy bass ( I love the amp mode ) Stylish ,,but bulky looking
Summary: I bought these headphones a little over a week ago, and thought I should post my impressions. I work in a small office, and sit close to my boss, who is constantly on the phone, so I wanted a noice-canceling big headphone for home and for the office.
Pros: Good in passive mode, great in active, and decent noice canceling
Cons: My ears get warm, and a bit too big and heavy for laying on my back.
