It’s been over two years since we first reviewed the PSB M4U2 headphones. While competitors have been replaced and updated, the M4U2s have stayed the course unaltered.
They remain as popular as ever, so we thought it was time to take a second look.
PSB might not be as familiar to you as some of the other brands it shares this test with, but it has been producing speakers for more than 40 years. The M4U2s are one of just two pairs of headphones it produces, the others being a purely passive model.
This is a big pair of headphones, though the folding design does help their portability somewhat.
Their size also makes them a little on the heavy side when compared with something like the Bose QC25, but the well-padded headband ensures your head never feels the strain, and large soft earpads keep them comfortable over your ears.
The pads are replaceable, with a spare set included in the box, alongside a 1/4in adapter, a second cable without inline remote and a carry case. You’ll need two AAA batteries to power them.
Most competitors use only one, but with two you can expect around 55 hours of ANC playback – a clear benefit.
