Luxury headphones are as much about what they're made from as how they sound. While other options for premium Bluetooth headphones are built from plastic and faux leather, the BeoPlay H4 opts for Lambskin, aluminum, and stainless steel construction with braided wiring. The result is an incredibly comfortable set of headphones weighing just over 8 ounces that delivers the sound quality you expect from Bang & Olufsen. The functional components are just as attractive as the headphones themselves: electro-dynamic 40mm drivers, 19 hours of use via a single charge, and on-device touch controls for answering calls and controlling the music. The H4's can be used with the included 3.5mm cord when the battery runs low, keeping the music going at all times.
