What's good

  • Clear, accurate sound quality
  • Comfortable to wear for hours at a time

What's bad

  • Passive noise-canceling useless in noise environments
  • Low quality MP3s and streamed audio sound even worse

PSB might be better known for their speakers, but that didn't stop them from releasing their second pair of over the ear headphones, the M4U 1. Taking some design cues from Beats Studio, the M4U 1 sports a shiny, plastic folding headband though they are more oval in shape. According to critics, the headphones are fairly durable and do not creak when twisted, though they also warn that a lot of stress on the hinges could ultimately lead to irreparable damage. When worn, the padded headband and earcups allowed reviewers to wear it without any discomfort, even after extended use.

Included in with the headphones are two cables: one just for connecting the headphones to the headphone jack and another with an inline one-button remote/microphone for phone calls.

Unlike its competitors, the M4U 1's don't emphasize bass. Instead, critics describe them as having a very neutral yet clear sound. At higher volumes, however, What Hi Fi describes the sound as somewhat "shouty" and adds, "A touch of subtlety wouldn't go amiss either." Due to its clarity, other reviewers discovered that low bit rate MP3s or streaming audio sounded less than desirable through the headphones. Noise cancellation is also not a strong point.

The M4U 1's also offer passive noise-canceling, which, according to most experts, worked well in quiet environments. In noisy areas, unfortunately, they found that ambient noise tended to leak through.

The general consensus is that PSB's M4U 1 model is an excellent pair of headphones for audiophiles. CNET states, "The M4U 1 sounds slightly better than the 2, and…[for] audiophiles who prioritize sound quality over everything else, it's hard to beat for the price."
