The hum is from speakers, not from the case. Yes, either of the
headsets work OK on another computer.

Then it is possible that the sound card has a problem.
Since the sound card feeds power into the microphone in
the handset, the filter capacitor on the microphone power
may have a problem that is letting 50Hz hum get injected
into whatever microphone is connected. You would not
hear this unless a microphone was connected. Since the
headsets work OK on another computer, that casts the
suspicion back on the sound card.

Perhaps the sound card just has the problem that it's a Soundblaster
Live! and you're using the mic input. A SB's Line in/out is
acceptable quality but the mic input is a joke.

Maybe is just that that's all you can expect from a $50 gamer
soundcard...- Hide quoted text -

Thanks Sergio Sanmiguel for your replying!
No, the soundcard works well with a separate (not in a headset)
microphone. Another card works the same.
