Review on Bluetooth V4 by Tracy Shelton

Not really wireless. The cable connects 2 earphones with volume and power controls in between. wires = potential problems. It would be very nice if the wires didn't hang out. The end of the right earcup and where it connects to the controls can move in and out, making the right side a cutout. It was a free gift so I'll try super glue if the sound is good. If that fixes it, I'll raise a star. Update: Couldn't get the right earbud to work again. I fiddled with it and it came out of the control mechanism quite easily. Explicit errors in the production process.
