Bang & Olufsen already offers headphones, and it has the B&O Play line to serve a mobile-oriented world. Wouldn't it be nice if the two categories mixed? As of today, they do. The B&O Play H3 in-ears and H6 over-ears apply that Danish love of aluminum and leather to the kind of headphones you'd want to pack with your MP3 player or smartphone. The H3 carries 10.8mm drivers, a mini bass port and a 20Hz to 16kHz range in a unibody shape that should hold up to exercise; the slightly more stationary H6 over-ears sport 40mm drivers and a wider 20Hz to 22kHz range. Both have primarily iOS-oriented in-line mics and remotes, although the H6 alone has Monster-sourced daisy chaining support to share tunes with others. Don't expect a significant break in B&O's premium pricing just because they're B&O Play-branded headsets, however. The H3 and H6 will respectively cost €249 and €399 when they hit some retail stores in May, and US pricing isn't likely to be much cheaper.
