Bose has recently introduced the QuietComfort 15, which is a successor to the QC2 model. The noise-canceling headphones boast new sound-reduction technology that is claimed to provide improved attenuation even in loud environments. The QuietComfort 15 also adopts TriPort venting to increase low-frequency output without artificially boosting the audio signal. Users can also remove the cable to take advantage of the noise cancellation without listening to audio. The headphones require one AAA battery that will last for up to 35-hours. The Bose QuietComfort 15 will retail for $300 when it is available this August 20th onwards. [iPodNN]
