I`m new here and I have a problem.My k800`s earpiece volume is very slow compared with my k750/w800/w810.k800 (with his original HPB-60) is slow compared with k750 and if I use hpm 70 is even slower.
Anyone with same problem???
What could I do to make my k800`s volume great(like k750)
I saw some post and I think I`m not the only one with this problem.
