I'm having many problems with mine. I think the lifespan of these are 3 months. I cleaned my case but the earbuds still have difficulty charging, particularly the left earbud. And the right won't pair after resetting to factory even though it's fully charged.
Dear friend,

Sorry about that. Please try to contact the seller about that first. If the seller fails to help, please contacted us with the receipt attached. Thanks in advanced!

Best regards

WARNING:
The UTWS3 already damaged two of my headphones left earpiece: Shure SE846 and today it happened with the 7Hz Timeless.
Something about that MMCX connector apparently isn't a great fit even when removing with a MMCX tool and connecting while holding everything straight and hearing the click.
Both of my right earpieces are now dead just because no signal is passing via the MMCX connector. My recommendation would be: Once you connected an IEM to the UTWS3 NEVER remove it until the device is dead. That MMCX connector is pure garbage

Does the left UTWS3 MMCX have a visible damage like a bend or too big pin? So far I have no issues with my UTWS3 and 5 MMCX connectors.

A bit hard to tell tbh, but as far as I can see: no, looks normal
Do you switch IEMs often? If yes then by hand or with that handy mmcx tool?

Fairly often I would say. Either I‘m switching earphones on my UTWS3/5 or between cables and earhooks.

I mostly remove them by hand, although I’ve read you could pull the parts out of the headphones or the cables, nothing happened so far.

I grip/pinch both sides with two fingers with the pinching fingers and push my fingers against another to „push“ out the plug
