Very nice product. I've been using them for about 6 months now. Started out at about an 8 I think and currently, I am at a 2. These don't bother my ears, and I'm highly sensitive to most metals. I did notice that if you have somewhat chubby lobes, when you're talking on a phone or sleep on your ears, the metal that flares out in the front can get pushed back which will cause a little irritation, but it's not a big deal and most probably wouldn't have that issue. I also noticed the bands are a little tough with very limited flexibility [at least for mine] so I had to use some spares I had lying around.
