Query: Nice Headphones but .....

I bought this unit a couple of months ago. It works fine, sound is ok but not as good as I expected. Now the battery doesn't last as long when I charge it so I tried to find replacement part. Well the JVC P/N is J46691-001, and it is $19.95 + shipping + tax. That makes it at about $28, almost half the price the whole unit!!!! forget it.
