A set of entry-level stereo Bluetooth headphones typically costs over $50 and usually closer to $100. But Tenqa's selling its Remxd Bluetooth headphones, an on-ear model that comes in black or white, for just $39.
So are they any good?
Well, the short answer is they're not bad. They have a pretty ho-hum design and are relatively compact, though they don't fold up. You've probably seen headphones with similar designs (Urban Ears was apparently the first with it). While they're not swanky, the headphones have a serviceable quality to them. Everything is faux leather, of course, and the material on the earpads has a little bit of a vinyl feel to it.
The headphones were easy to pair (they're compatible with most Bluetooth phones) and the Call Answer/End and Play/Pause buttons are amply sized and well placed on the left earcup, so you can operate them by feel. There's a rocker switch for the volume control that also can be used to advance tracks forward and back.
One small drawback: the headphones are a little big and didn't fit my head quite right. People with larger heads shouldn't have a problem, but I couldn't get as snug a fit as I might have liked. I could still wear them, but they felt a little loose on my head. In general, this type of on-ear headphone offers middling comfort: OK but not up to the level of on-ear models that feature memory foam earpads.
It's also worth noting that these can be used as wired headphones with an optional 3.5mm auxiliary cable, and they sound better that way, but you also charge the headphones through the same jack with an included USB cable. The trouble with that is that since it isn't a standard Micro-USB cable, if you lose it, you're going to have a problem.
