These worked a treat on my long flights. They reduced the roar of the 777 to a dull hum that you barely notice once you have music or other audio playing. Only negatives is the size (they dont fold) and the battery being hard to remove from the batt..

This is very good product, I have used them and they are fabulous, the sound is crystal clear. Only one drawback and that is that there is no rechargeable battery, that would be big win.

The headphones are good, overall sound-quality is average and the noise-cancelling works, there noise cancelling is just average (not that great as Bose QC25). If your a audiophile like me I would recommend the 'Audio-Technica ATH-M70x', it around the same price and the audio sound great.

I used this for the office, to work quietly and it performs great. The only sad part consumes battery power as crazy it last just 2 days on. just be aware to turn it off when you are not using it and done. :)

has long admired Audio-Technica's ATH-ANC7 and ATH-ANC7b noise-cancelling ‘phones and now the ATH-ANC9 ($349.95) has raised the bar higher still, both in terms of sound quality and flexibility.

Audio Technica's ATH-ANC9 Over-the-Ear Headphones don't have an overly heavy duty look to them, which makes them unassuming and clean looking. But, of course, headphones are about functionality.

We very much enjoyed the fit and performance of the Audio-Technica ATH-ANC9 noise cancelling headphones. The tri-level noise cancellation made these adaptable to nearly any environment or situation in which we would want to use these in.

In the unlikely event I ever again decide to pick a fight, it'll be with someone who looks weaker than me. Obviously, Audio-Technica has a lot more guts than I do.

Unzipping the hard case to check out Audio Technica's new ATH-ANC9 QuietPoint headphones, you expect no less bang for buck performance and value from the Japanese audio company's latest version of its excellent noise cancelling cans.
