I use these headphones exclusively in my back yard hot tub. Speakers don't cut it because you have to crank up the volume too loud to hear over the drone of jets, pumps and motors. With these headphones coupled with an Otter Box I can groove to my favorite tunes without disturbing the neighbors.
Waterproof sound quality, good frequency response and dependability make me very pleased with my purchase. I don't know about swimming but they work great around the spa.

I was a little disappointed with this product. With all of the info on your site I never was able to find out what kind of jack the head phones had. So when I tried to use them with my waterproof player they did not work. The delivery time was great though so I cannot be upset with Amazon fully.

I've tried a lot of different waterproof headphones and these are by far the best. ANY earphone will fall out while swimming unless you wear either a headband or an over-the-ear swim cap (I use the excellent Aqua Sphere silicone swim cap).

Once you get a feel for how to place the earphones under the cap, they are pretty fail-safe (I'd say only once in every 30 to 40 swims I get a little water getting between the earphone and my ear canal--no big deal). And the sound quality (under water) is truly spectacular.

(And btw, I use them with a waterproofed Ipod Shuffle from Swimman.net -- really great solution that clips onto the back of your swim cap.)

There is definitely a little bit of a learning curve to get started with these, but once you get a feel for putting them in right, they add about one minute to your pre-swim routine and are definitely worth it.

I've used these for 3 swims now in combination with the H20 Audio waterproof case. I'm not a fan of them at all. As soon as any water gets into the ear the sound basically goes mute. The seal of the headphones is not very good, so this happens often. You can turn the sound up extremely loud and still hear slightly, but then as you turn your head to breathe and the water moves within the ear the sound turns from blasting to mute over and over.

All in all I would say these are a lousy set of headphones for swimming unless you can find some way to seal your ear so no water gets in.

These waterproof earbuds are great! They fit nicely in the ears and are great when wearing a cap. To use them without a cap, I might want the larger size, since they can slip out easily. Great with a cap - no discomfort, etc.
