The product contained in the packaging delivered, is not the specific product I desired to purchase. After wearing them for a short period of time I had no skin left on my heals. 5M, so I figured I could order 6. I own the smaller Tribit XSound Go and am EXTREMELY pleased with the sound balance. One half hour of wearing strap came out Dimensions were spot on, and fits perfectly in the narrow space in our side entry, doesn?t block the doors or the electrical panel. I dont think they are quite as rugged as the adult ones but pretty dang close and for the price its great. Now that Ive cleared up some of the trolling nonsense of the bad reviews. Originally, I went by the recommended size guide, which for my women?s 8 1/2, I was advised to buy a 39 (a little too large). What a brilliant stylus!
