My sander is new and these pads do not stay on well at all. My club usually has 3 on hand but they tend to be worn out. Kudos to him, I wouldnt have done it! The product looks beautiful. all the music, youtube videos, and gaming i have tried sound great to me. I cant compare them to other bone conduction headphones but these exceded my expectations. These earbuds are amazing and fit well in ears. Unfortunately this speaker uses a different Bose Music app and cannot be paired with existing wireless SoundTouch speakers. Overall im happy with the purchase. I made the mistake of first buying a size 8 (shoe size 8 1/2) and they were a bit too small.
