Been through 2 of them already!
1st one became faulty 1 year and a couple month after purchase (so out of warranty).Tracks would randomly skip midway through playing, Bluetooth mode got stuck in a loop and the buttons became unresponsive.
As the company is in china shipping back to them from UK is expensive and they dont guarantee they will fix the problem so want to offer a discount to buy another 1.
2nd one has now stopped holding the charge only after few months of purchase and even though it is in warranty they do not cover the shipping charge.
Headphone were sounding good when working, but this experience has been a nightmare and leads me to believe the build quality may not be as good as they make out.
Pour le prix du produit difficile de faire mieux, la connectivité est stable et le stockage interne largement suffisant. cependant le qualité sonore et le volume maximum laisse encore à désiré. le confort est sommaire
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.
