Both cables (3.5 audio jack & USB charging cable) are 48-inches in length. I'm not sure about the frequency response rate but the freq range is 80Hz-20KHz and the speaker is rated 3W. The Bluetooth is v2.1 +EDR. I bought 3 different portable speakers from 3 different manufacturers and this one is by far the best value and sound quality for the money. It beats others selling in the $100 range.
