Summary: Good sound throughout the spectrum, though I prefer slightly more bass. Sound isolation is average; I prefer my modified koss "the plug" buds if I need good isolation. That said, even for double or triple the money, you'd be hard pressed to do any better than these.
Summary: I recently lost my other head phones at home and decided to try these out. I will never go back to the old style again. The sound quality is great and they are way more comfortable than I thought they would be. The noise canceling feature is great and I highly recommend them to everyone.
Summary: I love these ear buds. the memory foam is fantastic and I was a bit skeptical about that. I was also concerned about spending over $10 on earbuds. The sound quality is the absolute best. While the storage case is nice I do like the idea of a retractable cord better. I thought I had totally ruined them by rolling over one of the buds with my work chair. It did crack through, but the casing did not shatter. A little super glue and they are as good as new.
Summary: I bought these headphones to use at work, replacing a set of sony's that stopped working after about two months... and they do a terrific job of eliminating background noise. They work so well in fact, that I would actually be afraid to use them outside, for fear of being hit by a firetruck I didn't hear coming. These headphones do a much better job than any other I've used at eliminating the annoying sound of the wires brushing against my shirt or any other surfaces.
Summary: These are just the exact in-ear headphones i was looking for. The price is just right. They fit so snugly in my ear, because i am a runner and i was looking for in-ear headphones that do not fall out, unlike some of the other in-ear headphones out there on the market.
Summary: I use these in a number of different circumstances. Sometimes to listen to music while working on my laptop, and sometimes when working in my shop with power tools, or other outside activities. Probably the most handy thing about these is also their biggest annoyance. They block background noise extremely well. They do this to such a degree that I am able to run a router, table saw, miter saw, and belt sander without any other hearing protection quite comfortably.
Summary: I love, love, love these head phones. I've never been able to use the ear bud style head phone, due to them hurting my ears. These are extremely comfortable, and the sound is great. The sounds doesn't compare with my Bose over the ear head phones. But for this price, it is more than adequate. I use them with my mp3 player. They block out the noise from the train on the way to work. I also wear them while working out, and they stay inside my ears.
