The IPX4 rating means it can be used outdoors and in the rain.

The Philips BT6000B/37 Splash-proof Wireless Portable Speaker drops from $149.99 to $47.99 at Newegg. Even better, the shipping is free. This is the lowest price we could find for one of these speakers by $7. They have Bluetooth and NFC, an eight-hour rechargeable battery life, a splash-proof outer casing that's IPX4 rated, and two 6W speakers that can produce 360 degrees of sound. Sales tax is charged in most states.
