Headphoneus Supremus
I have them and did enjoy them.
I do agree that an IEM can cause more damage to hearing vs a full size can. I developed tinnitus after extensive listening with IEM's. Always listened at reasonable levels and used quality equipment but I got it anyway.
Did the whole ENT specialist\MRI thing and they said that many people do irreversible damage to their hearing with IEM and\or earbuds due to the design. I haven't listened to my hp's or system in months but still have the ringing at times...sucks
I used to have bad tinnitus but now it's just an occasional brief loud ringing in either ear. Older, bright buds used to give it to me bad right after using them. I've learned the earphone sig I prefer and also won't give me ringing. Occasionally I'll go over board but usually subsides after a bit.
