vorhandenen Surround Kopfhörer auf Stereo stellen. cant think of a single one. Works great, been on 4 trips already. Its easy to pull the earpads off, and putting on replacement earpads can be tricky but definitely doable. So far, they are certainly worth what I am paying for them from Amazon. Finally, when I pulled the headphones out of my ear one broke open. I was tired of my wireless earbuds constantly falling out so I ordered these. Throughout the tasks the stand held the bike firmly and I was never concerned that it may drop the bike or fall over. So I bought this second rack just to clean things up in the kitchen. Also good for behind doors for coats and other things that needed hanging.
