These were the last in-ear headphones I bought before I decided that I just can use them without feeling like my head is in a vice. That being said, these were the most comfortable vice-like in-ears that I found. Klipsch always prices their products very well and these were no exception, the sound quality for a pair of sub $100 headphones is superb. They were very good at isolating sound as is the way of most in-ear headphones since they're pretty much ear plugs. They were more bass heavy than I would have liked when compared to their tweeter...

I have been using these headphones almost every day for the better part of a year and they have proven to be very reliable. I did have to get them replaced about a week after I bought them for what sounded like a ripped cone in the left ear but no problems since, most likely a fluke since I haven't heard of the problem from anyone else. Bass notes are strong and mids are adequate, highs leave a bit to be desired but they produce an overall accurate sound. They do not, on the other hand, isolate noise very well so unless you listen to your music on...

I defy anyone to find a better sounding pair of headphones for less than $100. The response of these is absolutely spot on. The dynamic range is almost perfect and they have even frequency response throughout. It's so easy to pick out every instrument in a song played through these, no note hides and nothing is misrepresented. Grado was so close to making the perfect headphone for me that I almost tear up when I think about how much they hurt to use. The way they press on my ears makes wearing them for more than 30 minutes or so an impossibility.. so...

The only reason I have these headphones is because I got them for free. Having them for a few days now I thought that maybe if I the diaphragm loosen up they would get better.. no such luck. I'm listening to them currently and I feel that they are much to heavy in low frequencies and the mids seem to fade into the background. Highs are strong which is nice but they could do with much more accurate representation of the audible spectrum. This is what happens when a pair of headphones gets a celebrity endorsement. They fill them with bass for people...
