Koss KSC75 Consumer Headphones

I heard about these headphones and read the many good reviews on them, so I had to get a pair. I was very impressed with them at first, but after about thirty minutes, my ears were hurting. The sound is so crisp and brite they hurt. I admit that I have sensitive hearing in the high register, but I have never felt discomfort like that from headphones before.
The other thing I noticed about these is the volume is lower than with others. Not a huge problem but obvious. They are very comfortable. I hardly knew I had them on except for the briteness. I like the volume control. A very nice feature.
They get tangled very easily which is annoying and they can be cumbersome to put on.
Many people obviously like these and I understand why. I just can't use them, because of the strong treble.
