Wife and I upgraded to iPhone 7 so needed some BT headphones. I tried three different pairs from Amazon, found these and we are both happy.

Cheap, so no worries if they get killed with sweat or get lost. The sound is surprisingly good, not as good as my Bose wired headphones but very good for the price. They don’t like to transit through walls very well, but I keep the phone in a pocket and it works fine.
I bought these…great for the bike…not so much for running. The move around a bit (i am guessing due to the size of them) so the sound sort of “oscillates?” when running. Still don’t regret the purchase…they are great on the bike and I use a trusty waterfi iPod nano for running…which has lasted 3+ years…after destroying 3 nano’s from sweating.
Get the other Soundpeats with earhooks that I posted above in my link.
I own both sets (earhook vs nonearhook) and the earhooks work GREAT for running, whereas the nonearhooks are constantly falling out. (I wore a head/earband over the nonearhook ones for awhile just to hold them in, don’t need that with the earhooks.)
