Master & Dynamic MW50 Bluetooth headphones. MW50 are beautifully made and feature a machined aluminum antenna that provides triple the normal range, about 30m, for consistent connectivity and also feature apt-x for nearly lossless quality connection via bluetooth. The headband uses stainless steel in the folding components, a durable rich feeling cowhide wrap with extremely soft lambskin and memory foam pads. These are very supple and provide better comfort than almost any other on ear headphone we have carried.
The MW50 provide excellent sound with very good detail, never harsh or sibilant, slightly on the smoother side. Frequency response is very wide, at 5-30,000 Hz. The beryllium drivers are very high tech - the ultralight material is very rigid, commonly used in very expensive speakers, with great acoustic properties, making it an ideal light/strong material for a headphone driver.
Dual built in mics are included for good call quality. MW50 have a 16 hour battery life, recharge by usb (usb-usb c cable included), can be used wired (cable included) and fold flat into an included denim carry bag - these fold very flat and are perfect for a computer bag or briefcase.
Wired.com: "Performance [of the MW50 is] like a fancy over-ear headphone except these things are smaller, lighter, more comfortable and wireless.”
PC Mag.com: “Accurate, rich, crisp sound signature. Luxurious materials and comfortable, classic design.”
