These are by far the best underwater ear plugs for listening to your tunes.  The set includes several different sizes of plugs to give you the best fit.  I am a small female so I ended up using the x-small size.  I have not found any plugs that work all the time, but these do a good job and the sound quality is quite good.  I give a thumbs up on these and will buy them again when the time comes.

My wife has the life proof case for here IPhone so she wanted to get a set of waterproof ear buds. As soon as she opened this set she went right to the tub to test them out. And guess what? they work great!!! I would get this set for anyone with a life proof case.

I've used these headphones about 5 or 6 times in the pool for lap swimming with the H20 waterproof iPod armband.  I really like them.  My only issue with these is that you have to have a swim cap to keep them in place.  They have great sound quality, and inter-changeable silicone buds.  They come with medium buds installed but I needed the extra small buds to be comfortable for my ears.  I did find the best way to insert these so that they don't leak water is to pull up on the top of your ear and then press them inside.  Works great!

They are truly waterproof! Love them! Would buy other products!

I have only used these earbuds a few times with my waterproof iPod nano from Waterfi but absolutely love the quality sounds while I'm swimming! I have swam a few miles with these earbuds in and have not had any problems. They were definitely worth the extra bucks! The varying sizes of earbuds assures a perfect fit and the cord/jack attaches perfectly to my waterproof iPod nano. I would definitely buy these again, but I don't think I will have to for a long while!
