I like these. Easy to use, sound good (enough), no wires...
I think these are a hella value. Not perfect, as they do drop occasionally (mostly the left ear), and I have had one instance where they lost pairing with my Galaxy S7 (RTFM helped here) - but overall, they're a $#!+load cheaper than AirPods and, considering the source material I generally listen to, sound good to my ears. Better with music, less so with dialog - phone calls are OK, and the mic seems just about right. No one complains they can't hear me, tho it's difficult to hear myself...tho that's the case with every other headset (wired or wireless) I've ever tried. The fit is pretty good, too, and there's an array of ear tips - I have a pretty good customized fit with a different one for each ear. They stay in - I'm sweaty af and these haven't fallen out, which I have experienced with other IEM's. No cord to snag.
The buttons are small and a little hard to operate, almost impossible with gloves (I do a lot of work with my hands) and it's a challenge to operate them without pushing the IEMs a little further into my ear. The button layout seems out of convenience rather than what makes sense - power/pause button is at the front of the right earpiece and the rear of the left...tho I'm used to it now.
While there are certainly some quirks, IMO these are some good sounding, completely cordless(!) IEMs for an easy to swallow price. Once paired, take 'em out of the case and they're connected. They've supplanted a half dozen other pairs of IEMs I own, most of which sound better - cuz they are that easy to use while still sounding pretty damn good. Actually thinking about a second pair to keep in my work truck.
Would recommend to a friend.
