Aqua Soundz gives you tunes in the pool. Plug one end into your music machine via the 3.5mm plug and it will broadcast your music up to 50m (150′). The other end is a receiver and waterproof floating speaker but can’t be submerged. The transmitter needs 3 AAA batteries, the speaker needs 4 AA batteries. €59.50. You can also find them here.
Use it at dinners and gatherings with your friends so you can adjust the music without having to get up from the table. You can also use it to turn your terrace into an outdoor cinema: connect the TV to the transmitter and find a strategic place for the speakers, such as the lawn or the pool. Imagine watching a film while lazing about on a lounge chair?
