Narwhal is perfect for all outdoor activities like the lake, pool, beach, fishing, golfing, tailgating, or just for your front porch while enjoying some tunes and a tasty beverage. You can now enjoy your music with the convenience of carrying nothing more than your favorite cup with your favorite lid. When you really want to impress your friends, sync any two Narwhal Speaker Lids together to immerse yourself in stereo sound. You can even make or take phone calls or change your playlist through the built in microphone. Now that's the genius of NARWHAL.
