Sony's new waterproof wireless speaker will hit store shelves in Japan on June 21, just in time for the summer pool season. Using Bluetooth wireless technology, the round SRS-X1 can play music and sounds recorded in smartphones and personal computers for up to 12 hours.

At poolside or in the bathroom, the SRS-X1 portable speaker functions even if it is submerged for 30 minutes at a depth of 1 meter. Water temperature must be no higher than 45 degrees for the speaker to function.

The speaker weighs 185 grams and will be priced around 8,500 yen ($83), excluding tax.
