Audio-Technica's ATH-ANC9 QuietPoint headphones are definitely priced for audiophiles, most casual listeners are not willing to spend ~$300 on headphones whether they have active noise cancellation or not.  40mm drivers and a frequency response range of 10 – 25,000Hz give a hint towards the audio quality and there are three different noise cancellation settings for those who might sometimes want to be able to hear environmental sounds.  When [H]ard|OCP first looked at the headphones they were not sure as to how comfortable they would be after extended periods of time wearing them and were quite surprised that they were not bothered by extended usage at all.  Audio quality was superb, though [H] does point out that this might not be the best gaming headset, for that use you might be better looking to a headset which provides surround sound.  Those looking to enjoy audio without interruption from the outside world will like this product, if they are willing to pay the price.

"Noise-cancelling headphones are very popular with frequent travelers and those who live or work in noisy environments. Audio-Technica's new ATH-ANC9 QuietPoint headphones supply you with three modes of operation that have impressed us to say the least. Now you can get on with grinding in peace."
