Verdict

The Master & Dynamic MH40 Wireless (2nd Gen) is a premium over-ear headphone featuring custom 40mm titanium drivers, Bluetooth 5.2 connectivity with aptX Adaptive support, and a dual-microphone array with wind reduction for clear calls. Its luxury build utilizes anodized aluminium, coated canvas, and magnetic replaceable lambskin-wrapped memory foam ear pads, providing up to 30 hours of battery life with a quick-charge feature that delivers 6 hours of playtime in just 15 minutes. Main pros include its iconic industrial design, detailed hi-fi sound via USB-C digital audio, and a lightweight, durable construction; however, it lacks active noise cancellation (ANC), has a somewhat narrow soundstage for its price point, and can suffer from significant sound leakage at higher volumes.
