Summary: At first I couldn't get them to fit in my ears. I tried the different sized plastic pieces, but none seemed to fit. Finally I kind of jammed them in my ears. I was NOT impressed with the sound. I tried them for a while to see if they would get better, but nothing seemed to help. Not sure why they sucked for me and others loved them.
Summary: Let me start by saying I love Klipsch, I have over 5K in their home theater equipment, I have (and love) my Image One headphones (over the ear) but the S3 Headphones are garbage. I think the Koss in ear headphones from Ross are better... The comfort is tolerable at best. Don’t think about moving or touching the cord because it will vibrate through the cord and right into your hear giving me a head ache. For $50 (regular price) I would expect something far better.
Summary: I am baffled as to the comments made about these headphones and the glowing reports of low end high-proficiency. Perhaps I got a bummer pair, but I am very disappointed with the sound quality, whether plugged into my Galaxy S4 or laptop or ipod. They sound cheap and tinny to me with no low end capability. I am returning mine this afternoon.
