A few years ago I traded my ATH-M50's for an additional ATH-M40fs
I still feel I got the better deal, and they all still work (3 sets here).
Just sayin'

/Half the price and more accurate in my opinion
//They used to be about $69 new and have actually gone up over time; kind of unusual ..

///yes I admit, I traded $175 headphones for $69 headphones, and don't regret it!






I do not work here, but the benefits are still awesome
