The Bag of Riddim Bluetooth offers the same portability and astonishing sound quality as the original Bag of Riddim, but adds Bluetooth compatibility. The Bag of Riddim now also uses REWIND materials (made from organic cotton, hemp, and recycled plastic) instead of canvas. The universal 3.5 mm line-in audio input provides an easy connection option for hundreds of smartphones, mobile phones, and MP3 players. Additionally, the built-in USB port offers a charging option for smartphones, mobile phones, and MP3 players. The Bag of Riddim delivers enough bass to fill a room, backyard, or beach party with powerful and vibrant sound.
