I compare this product to another one I use in the pool. The other product comes with the "classic" earbuds and the usual troubles one can encounter using it: no matter how fit they are to your ears, eventually the water will protrude under the plugs and you'll need to stop to re-fit them. Finis duo eliminates the problem by using a so-called "bone conduction audio method". The speakers are held pressed on the temple bones by the goggles' strap. On the left speaker are the controls, very easy to reach and to use, once you get accustomed to them. The sound is clear and loud enough, even louder when both the player and the ears are immersed. Risking to repeat myself I have to emphasize that the sound quality (or intensity) doesn't suffer if some water enters into your ears. The memory is large enough to store hours and hours of audio content in mp3 and wma formats. Those were the "plus-es" of the Finis Duo; as for the "minus" parts, I'd mention two: 1. You can't make a playlist; it would be useful to organize your music according to the training routine: let's say you'd want to listen to some slower tunes during warm-up and cool-down and a more alerte/motivating ones during peak effort. You'll have to make do with whatever songs you loaded, played in a row or randomly. 2. The battery is advertised to last up to 7 hours; however, I never got mine to last past 3 and a half. I can tell that because I swim precisely 90 minutes daily and - if I forget to recharge the Finis Duo for two consecutive days - the third swimming session will be veeeery noiseless :). Overall: a very good to excellent product.Read full review
