Headphones

I don't know, man.

I starte by buying a bunch of cheap headphones for the recording studio (I needed to record a choir, and needed a way for every single singer to hear the background music without it being recorded by the microphone).

Then I bought a few more good sounding headphones (for those musicians that wanted to hear whether the recording sounded good enough).

Then I bought a really good sounding headphone for myself. And another one.

Anyway, I now have a few dozen headphones in the cupboard, another few dozen on my desk, some in my gym-bag...
