We followed the instructions carefully to prevent leakage from happening. High heat and works great! It can be worn for long periods of time. Its also not easy to back-up using a bow. They are nice and soft. The Bluetooth connection works fine, but you could spend half this much money to get a good sounding speaker with that capability. Once you set up this simple and elegant strap, the other bulky brittle solid plastic claw contraptions immediately seem ridiculous. I see in the product description that this YardStash XXL cover has a two-year guarantee, so Ill definitely be holding them to that! Glad I did. I cannot say if it is worth paying extra for the most recent edition, but you cant go wrong with any generation of these Sony headphones.
