I bought myself some new headphones, I use a Logitech USB micro & separate headphones to replace my "no name" set which are quite good, but tend to fall off frequently.

The new headphones, though, are disappointingly soft, and I can't turn the volume any higher. Have I bought headphones designed for listening to music etc. but not for use with a PC?

Frequency response: 21 - 18,000 Hz

Max. SPL at 1kHz  108 dB
