Both the Grado SR80i's and the Audio Technica ATH-M50's are top recommended headphones. I am looking for some for use at home with my computer. I currently use Sennhesier HD 202's. I like the idea of both open back and closed back, but I would obviously use the Grado's exclusively at home.
How much difference in the sound is there, and if I went for the Grado's would keyboard typing be audible over the music at moderate levels?
