Is it really safe to have electronics in water? Audio Unlimited has released a wireless floating speaker called the SPK-POOL. The speaker floats itself on water, so you can enjoy your music while in the pool or a bathtub. It provides a 150 foot clear signal which is able due to the 900MHz PLL circuitry. The speaker is beneficial for anyone who has a lot of pool parties. Hopefully, it was tested to make sure it was safe enough for it to be in water with people. The Audio Unlimited SPK-POOL is sold for $99.99.
