The iSplash floating speaker has made it possible to listen to music almost anywhere.
Although this is a tech gadget, it can survive in water, so you won't have to worry about another one of your devices getting water damaged. A great feature with this speaker is there is volume control on it. At your next pool party, you won't have to keep exiting the water to control the noise. Simply swim on over to the speaker and blast the tunes from any Bluetooth device; it can even be as far as 30 feet away.
If you're looking for a more relaxing (and possibly romantic) atmosphere, you can even use this speaker in the bath and keep the volume low. The iSplash floating speaker even has a light feature that emits a light blue for an extra calming tone.
