In my case, too, the fault was that the pairing mode could no longer be activated. The next day, a new pair was sent to the ZH branch via the hotline, where they replaced them without a murmur. And they did this even though I was told on the phone that they would send them in and check them first, which is why I would then have 2 headphones in the worst case. Top. Thanks for the answers!

I had a similar problem. I was able to connect the headphones to the phone once and it worked. Once the connection was interrupted, I could not re-establish it. The headphones could not be put back into pairing mode either. I had the device replaced under warranty. The replacement has been working perfectly ever since.

I am also very satisfied so far (for the price). So far, mine connect great and have never bucked so far - I would have them exchanged.
