Includes: NPB3 Bluetooth Speaker Remote Control Multi-purpose USB Charging Cable with 3.5MM plug to connect to an MP3 player or phone User Manual Warranty Card What makes this item awesome! Amazing Power and Sound Quality This speaker puts out a huge 30 watts of power. It’s extremely loud! I always bring a portable Bluetooth speaker to the courts when I play Basketball. I was frustrated that the speaker was never loud enough. That is why I decided to develop the NPB3. It is portable enough to take with you and it is still loud enough so you can hear it outdoors even if you are not sitting right next to it. I showed off this item to the employees here and everyone loved it! One of our people use this to listen to music at their desk. We have to tell them to keep it down because this goes loud enough to disturb our entire customer service team! LED Lights That Go to the Beat Each of the woofers has an LED light in it that blinks to the beat of the music. They look really cool with the silver woofers. The blue reflects nicely on the woofer! Huge Battery Life We use a high quality original 1200 mAh battery rated for up to 6 hours of playback with a charge time of 3 hours. Amazing Bluetooth Integration This speaker has Bluetooth 2.1 technology with enhanced data rate and a range of 33 feet! This guarantees a crystal clear signal even when you are far away from the unit. Pairing your phone or other Bluetooth enabled device is super easy! There is no password required. Multiple Listening Sources In addition to Bluetooth; the NPB3 features USB/SD playback and you can use the included cable and listen to any devices with a standard 3.5MM headphone jack such as a smartphone or MP3 player. We also added an AM/FM radio that has great reception quality.
