Not wanting to place product, but Grado make excellent headphones. iGrado are okay and reliably built, but the SR60's are the best. My ears have not suffered in over 9 years use. The only problem is the SR60's should go through an extension cable, and I even have to re-solder the headphone cable to the cans (the headphone speakers) cable every few months as the connection gets loose with friction.

[Note: These are not in-ear headphones]
