I've owned a pair for nearly ten years now and they sound as amazing as ever... though the older I get the more intolerable I am with the comfort factor. There I said it. They are uncomfortable. I'm constantly having to adjust the slippage of the height adjustment, the weight of the band isn't...

I found that the triple flange tips worked best for me with the X7i. Be careful when you take them out of your ears for a minute to talk or do something... the ceramic shells like to collide and my first set ended up getting a hairline fracture from this. IMO the design was not a practical...

A little late to this thread, but I own both the X7i and the H3. Both had to be sent back and replaced within the warranty and both replacements now need to be replaced again... but this time they are out of warranty and not worth it. For however great you think the sound is, the durability isn't.
