|Logitech UE Boom Bluetooth Speaker|
|Connection||Bluetooth 2.1 & wired 3.5mm|
|Communication Range||15m (50ft)|
|Frequency Response||90Hz - 20KHz|
The Speaker charges via USB (it takes about 3 hours to charge-up) and is rated at 15 hours of battery-life, which is more than decent for a portable Bluetooth speaker. I used it for an entire day from 9AM until 11PM, and another 2 hours the next day, before it went dark. Overall, this makes the UE Boom one of the very few wireless devices that has a battery life matching the rating given by the company.
