I haven't had a chance to test Tenqa's new REMXD Bluetooth headphones, so I have no idea what they sound like. But at just $40 they're some of the cheapest wireless headphones you can buy, and might be worth a try.
They of course support an A2DP connection to a Bluetooth capable audio device, and promise up to 15 hours of listening time on a single charge, facilitated by a miniUSB port. A built-in mic also means you can make and take calls when using it with a smartphone, while a stereo mini jack allows you to plug in a headphone cable so the REMXD can still be used when the battery is dead.
The feature set is, not surprisingly, pretty basic, as is the choice of colors—black or white—but even if they only sound 'just ok' they seem like a real bargain when they go on sale next month. [Tenqa via Android Community]
