Some caveats however.
1) the musical quality is limited, it hurts a little low, and too little agues. It is quite acceptable for bluetooth but it's painful in the long run, including changing of headphones.
2) the chip is small, but even if it can be clipped onto clothing, it is not simple. The best is to have a shirt pocket to put it. In practice, I have to hang on trousers or put in a pocket. It happens, but having a thread through the entire belly, it breaks the interest of the wireless device I think.
Otherwise, one of the best bluetooth products tested in this range, almost no flawless except the sound reproduction that does not suit me.
