I ordered these to replace missing caps on my model 515 trays. Worn these shoes most of the summer, I wanted something for walking the dog mainly, but didn’t want to use my walking boots in the hot weather, so I was looking for an alternative! Expensive and mid-range quality. They cancel the noice better than Beets and the sound quality seems very similar to both of us - although full disclaimer neither of us are experts of sound quality! my son is not rough with his toys. It is really annoying. 4-stars for connection modes - bluetooth, mic/speaker jack score. This shoe is built with very poor quality material and makes my feet feel very itchy if Im not wearing any socks. Not only are these a lower cost headset you can get the 800LX brand new at Gamestop with the Dolby Atmos code ($15) for the same total price of $150. AND THEN, here comes the best bit.
