Feel free to take the Outdoor Tech Big Turtle Shell Wireless Boom Box wherever you roam. Its IPX 5 housing provides water resistant, dustproof, and shock resistant protection so you don't have to worry about it in parties, beaches, and bathtubs. Bluetooth compatibility lets you connect the Big Turtle to Bluetooth compatible devices without any wires, and the stereo input allows cords if you're behind the times. A built in microphone lets you talk to the Turtle too, so you can change the volume, tracks, or answer a phone call with the sound of your voice. The Big Turtle also features a big battery that'll keep the music blasting for sixteen hours of playtime and 325 hours of standby. This battery also charges smartphones up to four times and your GoPro camera six times.
