My sander is new and these pads do not stay on well at all. Having bought numerous shoes for him, and him getting through them quickly, it?s great to know these will last. So it wont drive very high end headphones, but this thing wasnt designed for music. When you put them on and then stand on them youll feel the tightness but youll note that part of the tightness is due to the cushioning all around. The volume is not very loud at all and is distorted. I use it every morning and night on clean skin and the results are very pleasing. However, when I opened the box there was what looked like floor sweepings, a tissue and a straw strand from the broom used. Seriously, this is so bright (with no way to turn it off). The rubberized coating on either side of the keyhole, along the base, is genius! Quality item I would recommend.
