Verdict

The Master & Dynamic MH40 (Gen 2) is a premium over-ear headphone featuring 40mm custom titanium drivers with an impedance of 32 Ohms and a frequency response of 20Hz to 20kHz. Known for its iconic industrial design, it is constructed from anodized aluminum, coated canvas, and genuine lambskin leather with magnetic memory foam ear pads. Its main pros include up to 30 hours of battery life with fast charging (6 hours of playback in 15 minutes), high-resolution 24-bit/96kHz audio via USB-C, and Bluetooth 5.2 connectivity supporting aptX Adaptive. However, notable cons include the lack of active noise cancellation (ANC), relatively small on-earcup physical buttons, and a design that does not fold for more compact storage.
