A
Excellent complete kit to revive XVive U4 IEM batteries
Alaistair 06.09.2025
We have had 6 pairs o XVive U4 IEM sets in use every week for 4 or 5 years. We had noticed the battery warning lights starting to come on a bit earlier that when they were new.

The battery kits provide everything to replace the internal batteries in the transmitter and receiver. There is also a 20 minute video that provides step by step instructions.

Everything is provided including the tiny screwdriver, and new sticky pads.

Opening the transmitter is a bit tricky - but the exelent kit includes a brand new antenna cover, as the old one does get a bit damaged when removing.

The whole process takes about 20 minutes and makes the U4 as good as new!

Top Ersatz Akkus für U4
Graziano S. 04.03.2025
Nachdem nach 4,5 Jahren der Akku vom Empfänger schlapp machte, wollte ich mir einen neuen Empfänger kaufen. Zufällig sah ich das es Ersatz Akkus gibt und hab die bestellt. Mit einem Link gelangt man auf ein YouTube Tutorial, der Austausch der Akkus ist easy und schnell . Kläre Kaufempfehlung.
