Langlebiger Akku,etwas teuer,aber es lohnt sich in das Original zu investieren.Schneller Versand,gute Qualität.
ALL ok
Hard to tell! I can only seem to get 45-60 minutes of earphone use at a time before charging and now only the same time! I then get two beeps for several minutes at a time and then they no longer work. I believe I used to watch a 3 hour football game with them, now still only the 45-60 minutes before having to re-charge them. What's up with this?

Orginal ist halt immer das Beste! Alles Andere ist Zeit-und Geldverschwendung.
It does what it promises & the fast delivery to the door was ecvellent
