The batteries in these things usually are replaceable if you know how to solder two or three wires. And it will take more than a couple of years for the battery to become bad. But there's still no way in hell that something like this is worth $200. I bought wireless headphones on AliExpress for around 30 euros and they have a battery life of 110h. Every time I hear sudden beeps I freak out and I think that something's wrong with my PC. But it's just the headphones warning me that the battery is at 10%, which happens after a couple of weeks of use so I can never get used to it. That's what I want. I want wireless headphones that can last a long time. And they sound fine for gaming. I don't use them for listening to music. But for gaming, a set of wireless 30 euro headphones that lasts 110h is just hard to beat.
