Top critical review
Only suitable for the heads-always out of the water wimmer.

Don't get this is you swim seriously (as in head-down, tumble turns etc.).
If you swim breast stroke and don't get your head very wet, it's great.
Sound quality is one of the best for this type of product, loud enough and well defined high frequencies.
I swim front-crawl with me head down, this would last about 20 minutes and them one channel (ear) would stop working.
Recovered 3-times once dried, but on 4th use one side never recovered so returned and obtained full refund.
It's a shame as the sound quality I think is better than the Sony units I use, but the Sony still work after 3-years, these didn't last 2 weeks.
