Rockville ROCKBOX 6.5" 100 Watt Portable Rechargable Bluetooth Speaker w USB/SD

Rockville designers engineers and product development managers spent 6 months developing the all-new ROCKBOX. We developed what we consider to be the best combination of portability and sound. The ROCKBOX is an extremely light-weight and portable Bluetooth speaker that has amazing sound and an amazing battery life. Pure sound! The ROCKBOX has 100 watts of power! The most impressive thing to me about this speaker is the sound quality! The bass is incredible! I compared this against a $300 home theater speaker and this had way better bass! The highs are also crystal clear. To really test this speaker hard I turned the volume up 100% to the max turned the bass up 100% to the max and played some bass-heavy rap songs and all I can say is wow! There was no distortion at all! Even when maxing this thing out the music is loud and clear with no distortion! When I say loud I am not exaggerating. At top volume you are likely to hear complaints from your neighbors. The ROCKBOX has a top of the line Bluetooth module built in. The Bluetooth range is around 65 feet. Once paired for the first time it will auto pair to your phone in under 5 seconds from when you turn the unit on. The Bluetooth volume level is excellent and the sound quality is excellent in Bluetooth mode or any other mode. The USB input allows you to play back your songs stored on a thumb drive. You can also connect an MP3 player or other USB device to the speaker through the USB. The SD card slot allows you to play back songs stored on an SD card. There is also a 3.5MM auxiliary input to connect a phone or other audio device. You can also use the aux input to connect this to your computer or laptop. We also added an FM radio. The radio will only work when you plug an aux cable into the aux input. The aux cable acts as an antenna to get you radio reception.
