Just need a right side mic and this is not that. instead of those others that last about an hour or a bit more if the volume is low, I have had a day time sleep then worn them all night and still not run them out of charge. It should not be hard to hang a rack on the wall. The only reason I gave three stars was because the electric razor and bikini shaver are great. I would recommend these if you have narrow feet (may not work for wide feet because the sides are open and your feet may bulge out). Having used wheels/pedals/shifters off and on for a long time, i just CANT RECOMMEND this product. This headset was the cheapest quality brand I could find with the things I needed. I suffer from plantar fasciitis and as soon as I put these shoes on and started walking, my pain lessened until it was gone. This is an AMAZING speaker! If 3 damp towels are placed one in front of the other, they are touching and would not dry properly.
