Bought SONY Sports MP3 Player NWZ-WS615

Just bought SONY Sports MP3 Player, model number NWZ-WS615, cost 199 SD, it is waterproof with Bluetooth can connect to Smart Phone, today I tried it by wearing it to the swimming pool, waterproof feature is the reason I chose it, I have copied some mp3 song and BBC radio clip into WS615, need to change to the waterproof earbud, and with the waterproof earbud, the sound becomes quite small, you need to turn up the volume, it is okay while outside of the swimming pool, but from my personal experience the music/BBC radio clip effect is not quite good while you are swimming, as you are flapping/stroking the water while you are swimming, I am a free style swimmer, and other swimmers also will do the same thing, it is quite noisy surrounding actually, as I can anticipate this outcome, you cannot expect a good effect while there is so much noise, so I am quite okay with it,  and this model might be perfectly suitable for running/jogging.
