The problem here is getting these to stay in place when seriously running.
Cal Coast
The cord sticks to my neck, and as I run it gets pulled a little bit across my neck with each movement, eventually pulling on my right ear.
William Hoke
I used at work (in an office) for a week and the rubber started to come off and at about a month one of the ear buds broke off.

Let me start by saying that I have been on a very expensive quest this past year to locate in-ear headphones which met what I thought were fairly reasonable standards. After all every manufacturer out there has some sports figure on the packaging so how hard could it be right? I needed headphones which were durable, stayed put while: running, using the elliptical as well as laying flat while lifting weights and doing crunches. Finally and most importantly they needed to be highly sweat resistant. The headphones needed to meet these criteria while sounding phenomenal. If you are reading this you have probably been on the same quest and can't believe what a pain it is to find something that meets such obvious standards. Well I'm happy to report that you need not look any further!

These ear buds are the best I have ever owned and let me tell you I have tried several. I have a drawer full of failed headsets which all managed to die right outside the return policy. The warranties are useless since they will only replace them with what you already have which you know will only fail in a few weeks (if you are that lucky).

Sound:
The sound from these headsets is very rich. These headsets are capable of fooling your senses. I've had to pause music thinking there was external sound when it turns out it was simply sounds and instruments I didn't know was in the song because it was inaudible with previous headsets I've owned. It is literally like rediscovering your own music collection. The bass gives you the feeling of having a mini subwoofer in your head. Unless you have been to way too many Slayer concerts the volume these headsets can reach is simply stunning and will over power even the noisiest environments all with NO distortion. The Chicago subway is no match for them.

For years, I've been searching for a really good set of earphones to wear in the gym. Most headphones I've tried have been to fragile, breaking after a couple months due to repetitive motion. All of the headphones I tried got to be pretty gross (I sweat a lot). I didn't want the headphones to fall out of my ears (like the standard apple earbuds), or give me a headache (like most of the behind-the-head models). When I read that these headphones could be cleaned off under running water, I ordered a pair of these immediately.

These headphones are, by far, the best pair of headphones I've ever owned for active use. They're pretty comfortable, the sound quality is very good, and like other in-ear headphones, they do a good job keeping out noise. They're so good that I'm planning to leave my noise-canceling headphones at home on my next flight, and just travel with these.

Unfortunately, they're not perfect. As other reviewers have noted, the earbuds are attached to uneven cable lengths; the cable for the right ear is much longer. This means that you have to put the extra cable around the back of your neck. The headphone cord is made of a rubbery material, which I find sticks to the back of my neck, causing the headphones to pull a little when I move. Not a deal killer, but something to think about.

The angles connector is also slightly awkward. Recent iPods and iPhones are designed to have a connector that sticks straight out. (For example, take a look at the armbands designed for the iPod Nanos.) I'm slightly concerned that this will lead to more cable bending, possibly shortening the life of the headphones.

However, those are pretty minor quibbles. This is the best pair of sports headphones I've ever used; I already ordered a second pair of these for my wife. I'd recommend these to anyone who wants a pair of good quality headphones for exercising.

this review is based on my first use - i could wait after a few runs, but i guess i'm just excited to use them and i figured it wouldn't change with subsequent uses. i was originally considering the Sennheiser MX85 twist to fit, but saw these and decided to give it a shot. i have shure e3c, some cheapo sony in-ear, and they both slip everytime i run. i live in dallas, so heat and sweat during runs are a given.

as other reviews noted, the NEGATIVE aspects i agree on are:

1) the wire material is tacky and does tangle;
2) the case is pretty useless - i had to roll the cord around 3 fingers and stuff it in there - when i pull it out, it's a struggle to untangle;
3) they still slip out of my ear going into my first mile (due to sweat) and i normally run 3-4, so it requires alot of adjustment - i eventually gave up
4) i did get some wire noise (described as the noise from a stethoscope), but it wasn't too annoying

POSITIVE:
1) CLEAN and well-balanced sound - i have to set the bass on my eq to half and still get good punch. highs are crisp
2) very comfortable - i used the smallest adapter
3) can't comment on the rinsing to clean - first day using it
4) wire length didn't bother me as long as i let it run behind my neck - the clip that was included helped

if they stayed in my ear for more than 2 miles, then it would probably get 4-5 stars, b/c that's my MAIN ISSUE about in-ear sport phones - they can't stay in - is it even possible?! i can see how these phones are good for gym and non-agressive workouts, but it doesn't work for me on my runs. i guess i could go for the twist to fit and see how those are. otherwise, i'm still open for suggestions on good sport headphones.
