Verdict

The PSB M4U 8 MKII is a closed-back wireless headphone featuring 40mm dynamic drivers and an all-digital signal path with Bluetooth 5.0, supporting aptX HD and AAC codecs. Its standout characteristics include RoomFeel technology, which simulates the expansive soundstage of high-end loudspeakers, and Audiodo Personal Sound for custom audio calibration via a hearing test in the PSB app. Key pros are its rich, balanced sound profile (10Hz–20kHz frequency response), exceptional comfort with gyro-suspended 15-degree tilted earpads, and the unique ability to use rechargeable or standard AAA batteries for up to 25 hours of active runtime (18 hours with ANC). However, notable cons include its relatively heavy 342g weight, unintuitive right-earcup physical controls, and active noise cancellation that is often described as less effective against mid-to-high frequencies compared to class-leading rivals.

  • Generous accessory package including a sturdy hard-shell case and extra ear pads

What customers dislike about PSB M4u 8 MKII?

  • Active Noise Cancellation (ANC) is only average and not class-leading for the price point
  • Battery life of 18–25 hours is considered disappointing compared to competitors offering 30–50+ hours
  • Physical controls can be unintuitive and difficult to distinguish by touch alone
  • The aesthetic design is often described as bulky, dated, or 'bland' plastic
  • Presence of a low-volume ringing or electronic hiss when ANC is on without music playing
  • No support for high-end Bluetooth codecs like LDAC
  • Lack of water or sweat resistance (no IP rating)
