And these definitely give better sound than the best of my bluetooth buds. They arent compatible, they are the wrong size and shape (Ultrasone is circular these are oval) So these are a game changer. Its the real thing. There is no good reason to use regular earphones when skiing or biking, when you can use these instead. That being said, I had no idea these comics existed until Amazon put them forward as a recommendation. The construction is great on these. Though I am not sure I would say that is a negative. Pairing is effortless. This product is great & gets 5 stars ☆☆☆☆☆
