Bose QuietComfort 2's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component produces low frequencies that can be heard, and if it makes any changes to the signal on its way through. The Bose QuietComfort 2's highest frequency is at 20,000Hz, high-frequency response measures if and how well a particular audio device makes high audible frequencies and if it makes any changes to the signal on its way through.
The Bose QuietComfort 2's battery life is 6 hours, these last longer than 5 hours of listening which is considered average before recharge. A device's battery life is given by the manufacturer, and with more battery hours, you get to use it for longer and requires fewer chargings.
