Welcome to Headphone Heights, the place for all your ear bud discussion

Grado SR-125, HP-1, 325; Koss Porta Pros & earbuds...

... and a home brew (1999) dedicated portable headphone amp that alows 8-pin opamp swaps, NiMH on board recharging, switchable 9-18v power to chip, and "crossfeed". Can hear a gnat flying across the recording studio in ambient stereo.

I still return to the '90's vintage Grado SR-125's as my "reference".
