“Sennheiser HD280 vs HD555 My friend purchased the HD280's from BestBuy and they sound phenomenal. I can't remember if they also sold the HD555 headphones though (I think they had it..) But I want to know which is the overall better headphones to buy for music and video production. 280's seem like the high end of the "pro" series while the 555 looks like the mid-range of the "audiophile" series. So I'm just wondering which is more worthy purchase.”
