this is the SoundPeats Q9A, a dirt cheap, in ear, wireless sports headphone that's popular among Amazon customers because it only costs $25 and vaguely resembles Beats Powerbeats 2 Wireless sport headphone that costs six times as much.
Aside from the low price I'll tell you what's good about it.
Relatively comfortable to wear.
Stays securely in your ears and comes with not just one but two carrying cases.
it's also supposed to be sweat proof and holds a solid bluetooth connection with minimal pick up.
Battery life is rated at five hours, which is OK but not great.
As for the bad, well the Q9A's construction isn't exactly first class and it just doesn't sound all that good.
It sounds recessed, distorts even at lower volumes, and has a harsh edge with anything more complicated than easy listening music.
But hey, if you're not a critical listener and just want some tunes piped wirelessly into your ears while you're working out.
The Q9A is worth considering, after all it's only 25 dollars.
