Review on iJoy ISO Wireless Over Ear Foldable Stereo Headphones with Bluetooth 5.0, 30-Hour Battery, Built-in Microphone - Black/Red by Justin Early

I didn't have Bluetooth in my headphones at first and was very frustrated. Today I paired the phones to my iPhone and got excellent headphone reception. Unfortunately, a new MP3 player I bought a few days ago could be paired and shown as connected, however no sound came through the headphones. So I suspect that Bluetooth doesn't work with all Bluetooth devices. My second problem was that the charging cable didn't fit in the headphone jack, I solved this by simply rotating the phones. It may seem strange, but for some reason it worked. I took off one star for the lack of instructions. I hope this update gets to the press before I release it. By the way, after pairing with my iPhone, the sound is amazing.
