I am very happy to have this item. One small disadvantage it that microphone is not good enough. But anyway - I can swim with the headphones - that is awesome:)
The Headphones are o.k and they help me swimming. However there are some firmware problems: they always connect to bluetooth first. You must explicit switch to tf mode yourself each time. And: Even in tf mode it always speaks the change of the bluetooth status connected/disconnected. While swimming this occurs very often. So Bluetooth is not usable (obviously not while swimming, but i am already in tf mode. It is not usable at all because you must remove pairing). Since i removed bluetooth pairing completely it works also in tf mode, and the headphones do not tell me a connecting status anymore.
The headphones are decent and comfortable to wear in terms of Bluetooth, however when listening to music with the MP3 mode, there is occasional stuttering of songs
Sits well but fit takes a bit of fiddling, would be good to have smaller band option for smaller heads. Charging cable seems flimsy. No carrying case.
The microphone stop working but everything else y excelent
