So, I'm about to go for Sony MDR 1000X/B, they'll be my first wireless headphones, but I want to know couple of things.
1) What's the difference between 1000x and 1000x/b
2) In case of battery deteriorating, will I be able to do something about it?
I'm planning on using them for a longer term, and want to know if they'll serve me long enough. I've already used them, and the sound is really good for the music I listen to.
