Good sound quality; comfortable fit and good seal to prevent water intrusion.

I've tried several different fits via the supplies they provide but nothing works

The sound is really good, they are comfortable and stay in my ear and the assortment of tips allows you a chance to get the perfect fit.

The fit isn't very good and they often fall out or allow water into your ear canal.

My recommend is to make sure you use the correct Eartips to ensure a good fit

Also appreciate the fit.

The different ear bugs allow you to choose the right fit

excellent sound and comfortable fit

Good fit

The fit on these isn’t great, had a lot of problems with water in my ears until I started using Vaseline (something called swim goo which came with my underwater iPod.

The sound is great and I have found that the fit, while using the recommended "fitgoo", is just perfect for a really enjoyable swimming experience

Together with 'half moon' fitting pieces a very good and secure fit was possible

Various earplug sizes included to find the best fit for your ears

These sound GREAT, and with the many choices of eartips I am able to get a comfortable, leak-proof fit in my ears (I use the "puffy" tips.

Solid quality sound, easy fit...happy!

I experimented my first two uses with it and did not have a good fit in 1 ear.

I assume anyone would be able to find the right fit for them included.

The headset works well, but as others have said, take the time to make sure you have a good fit.
