4.2

(702 reviews)

Long 30‑hour battery life with fast‑charge (15 min gives 6 hours playback) supports all‑day use.

✓High efficiency of 104 dB/mW makes the headphones loud even when driven by a phone.

✓Replaceable magnetic ear pads wrapped in memory‑foam offer comfort and easy customization.

✓Dual‑mic array with wind reduction ensures clear call quality and voice‑assistant compatibility.

✓Bluetooth 5.2 with aptX Adaptive, multipoint pairing, and up to 30 m range provides reliable, high‑resolution wireless connectivity.

Cons

✗Weight can reach up to 360 g in some reports, making them feel heavy during long listening sessions.
✗Passive isolation only; lack of active noise cancellation or IP rating limits use in noisy or wet environments.
✗Maximum power handling around 100 mW means distortion can increase when paired with high‑power desktop amplifiers.
✗Ear‑pad dimensions (58 × 35 mm) may not fully seal for users with larger ears, reducing isolation.
✗No spatial‑audio or immersive processing, resulting in a lower immersiveness score compared to some competitors.

From Expert Reviews

Criticized by Experts

✗DIY‑Audio‑Heaven points out the headphones are heavy and may not suit users with larger ears due to pad size.
✗Professional reviews mention limited power handling (~100 mW) leading to distortion on high‑power sources.
✗All sources agree the lack of active noise cancellation and any IP rating is a drawback for noisy or outdoor use.

Expert Opinion

Professional reviewers commend the MH40 Gen II for its premium materials, refined titanium drivers, and long battery life, noting the sound is detailed and efficient. However, they criticize the lack of ANC, the relatively high weight for some users, and limited power handling that can cause distortion with high‑output sources.

What Users Say

Common Complaints

Weight feels heavy over long sessions, ear pads may not seal for large ears, lack of ANC and IP rating, and limited power handling causing distortion on powerful sources.

Master & Dynamic site/iMore

“Pretty light at 280g despite looks; premium materials justify build; big titanium drivers.”
YouTube reviewer

“Luxurious build ("what you're paying for").”
Consumer forum comment

How It Compares

vs. Master & Dynamic MW65

Advantages

✓MW65 is lighter at 245 g, making it more comfortable for extended wear.
✓Both share the same 40 mm drivers and 32 Ω impedance for comparable sound quality.

Disadvantages

✗MW65 has a shorter battery life (24 hours) compared to the MH40's 30 hours.
✗MW65 does not offer the same premium aluminum and lambskin leather construction as the MH40.

Choose the MH40 for longer battery life and premium build; choose the MW65 if you prioritize lighter weight.

vs. Master & Dynamic MW75

Advantages

✓MW75 includes active noise cancellation for noisy environments.
✓Both provide similar driver size and Bluetooth connectivity.

Disadvantages

✗MW75 is heavier (~330 g) and more expensive, while lacking the MH40's ultra‑premium aluminum and leather finish.
✗MH40 offers longer battery life (30 hours vs MW75's shorter ANC‑on time).

Select the MH40 when you want premium materials and longer battery without ANC; select the MW75 if ANC is essential.
