I had the chance to review the AYL Wireless Bluetooth Headphones model AX8 recently from Amazon.com and found that these headphones are great for general use. I tried them while running, talking on the phone, walking around town and general use while connected to my iPhone 6s plus and found that they are pretty great for $30 Bluetooth headphones instead of dropping $200 for Powerbeats Wireless earbuds. Admittedly they weren't as comfortable as the Powerbeats or JayBird headphones, but then again, for the price you can't really argue with it.
While the fit may certainly be a personal preference choice, I happened to think that they are pretty great and would recommend them if you're looking for a reasonably priced pair of wireless earbuds to go running with or to use at the gym. The microphone is set up a few inches off of the earbud which can be a little annoying but most of the people I called didn't seem to mind.
