Master & Dynamic Enhances MH40 Headphones with Upgraded Drivers and Extended Battery Life

The updated microphone setup includes wind reduction, and you can opt for Sidetone in the app to hear your own voice during calls. Bluetooth 5.2 gives the new MH40 a range of up to 100 feet (30 meters), and the headphones support AAC, SBC, and aptX Adaptive (up to 24-bit/96kHz). However, the headphones do not feature active noise cancellation (ANC). For ANC, the company offers the expensive MW75 headphones.
