Is it possible to change the battery in wireless headphones in the service?

Question

Headphones

Hello everyone) I decided to make myself and my wife a gift for the new year. As a fan of Apple technology, the choice was only between Beats and Apple's on the H1 chip. Apple headphones did not fit because for some reason they do not think about autonomy at all, 4.5 hours is all that headphones can offer for a small amount. I need a universal option and run in the gym and be in touch for 8 hours at work, if anything. In general, I chose Beats fit pro with their 7 hours of operation and sports fit. Then I began to read more about wireless headphones and in some places they write that wireless channel headphones are not suitable for repair at all. Type the battery sat down and all. It somehow turns out not ah. Like I bought headphones for 14-20 thousand, I used them for 2 years and went to the store for new ones. So I want to understand if this is so, or do they still change batteries for everything in service centers?
