Years ago I have always used the brand with gamer mice and I just found out that the brand had Bluetooth gamer headphones for phone and PC (yes PC, I thought so)
Look for reviews about the best ones as time went by I realized they have a particular problem, their battery degradation and either the L or R malfunction, I bought a Damaged 2 versions, the Mercury edition 2019 and the pro, both with the same battery problem, luckily I found batteries on aliexpres,
To open the TWS you require a thick eyelet blade, making them with the first hammerheads is safer and easier than the pro ones since these, They have a Flex that makes a touch.
This is the broken Flex, I tried to put a direct cable but I realized that it is a double contact Flex, there was no way to save.
The problem with the charging base I assumed that it would be a matter of the chip that did the hal effect (when the lid is closed, the charge passes) but no, it stopped in a matter of seconds when measured with the tester, So I removed it to leave it direct and still the problem persisted.
so I adapted a card from a redmi tws and added a coil to charge it wirelessly

Instalation
the razer headphones on my Opinion are horrible, build quality, rapidly degrading internal batteries, and lack of basic features such as wireless charging and app update failures,They are the worst product of tws headphones of the brand in my opinion, I have not tried the last ones, For the price they cost, there are better options on the market.
