Premium Handcrafted Earphones

The Master & Dynamic MW07 are true wireless in-ear earphones built with handcrafted acetate housings and a hand-polished stainless steel charging case. They use custom 10mm Beryllium drivers and proprietary Fit Wings in two detachable sizes to create a secure, noise-isolating fit. Optical sensors automatically play or pause audio when the earphones are inserted or removed. This design targets listeners who value artisan materials and a tailored in-ear seal.

Bluetooth Range and Battery Limits

Connectivity relies on Bluetooth with a stated range of 20 meters and quick pairing technology for fast device linking. The earphones provide up to 14 hours of total listening time when combined with the three additional charges stored in the case. Users who need longer continuous playback without access to the case or who require a wired connection option will find this product does not meet those requirements.

Acetate and Steel Construction

Each earpiece is made from acetate, a material that gives every unit a unique pattern, while the charging case uses hand-polished stainless steel for durability and a premium feel. The case stores the earphones and supplies the extra charges but does not support wireless charging. The Fit Wings attach to the earbuds to improve stability during movement, and the optical sensors handle automatic playback control without physical buttons.

Questions about this item

Which capacity should I choose for the charging case?

The stainless steel case holds three extra charges, giving a combined 14 hours of total listening time before you need to plug it in.

What does the 10 mm beryllium driver mean for everyday sound?

The larger driver surface moves more air, so bass stays tight and detailed while vocals and high frequencies remain clear at normal volumes.

What does the 20-metre Bluetooth range mean in practice?

In open space the link stays stable up to that distance; walls, body shielding and other wireless devices will shorten the reliable range.
