So, I am looking for headphones in the 300-500 range. I listen to mostly indie rock and electronic and I have been trying to choose between HD 600's, and the Pro 900's. See, I want to here the " buzz of guitar strings" that the HD 600's offer but my situation doesn't really support open ear headphones. A good amount of time I spend listening is on the bus, which is noisy and therefor not the best environment for open ear headphones. What are some alternatives for great quality closed headphones besides the pro 900's?
