Bests & Worsts Reviews from Amazon

6.17.15 UDPATE: The QY8 model is out at the same price point so you may want to check that out. I have stayed away from Bluetooth devices, as a whole, since their introduction into the market. I am shocked at the quality of these headphones. I expected something better than the mass produced garbage in `impulse racks' but something moderately okay due to the low-cost Bluetooth. What I got literally, figuratively speaking, stunned me. I initially had issues with these on an Android phone - they did not sound good. Then I paired the headphones with an iPhone. Perfect operation and deep bass while streaming audio. I went back online, and found the Droid solution from 2013. It was my device (clearing the Bluetooth data). Gave it a go and everything is all good. I'm impressed. I don't take much of anything seriously, but I am an audio snob. I've tossed many free or almost free headphones as I wouldn't even let my kids use them (they are audio snobs in the making). I figured these would be `okay' as a backup and I'd stick with my corded Bose. I will now keep my Bose as backups in my gym bag since they are still quality gear and don't require a charge. If you decide to purchase these, I encourage you to test out the small, medium, and large covers that are included. It ships with medium attached and the rest in a bag. Obviously go with the ones that feel the most comfortable - just tilt your head side to side. If they start to slip out at all, rotate the back piece. If they continue, then try the next size up. With anything, I will circle back if I have significant issues. One note: The tiny rubber flap for the micro USB charger is a pain to remove (for charging). If I don't rip it off, I'm confident it will fall off. This is a non issue for me, but wanted to point it out. Tested November 2014; Product supplied by Soundpeats audio for unbiased evaluation. PS Driod users - If you have drop-outs try going to settings, apps, Bluetooth share, clear data.
