Noise Cancellation Audio Technica is no newcomer to noise cancelling headphones. They have released a number in the past including the best-selling ath ANC7b's. So what makes the ANC 9 unique? Well it features a new technology developed by audio Technica known as tri-level noise cancellation.

Very good audio quality; nice accessories; tri-level noise cancellation is quite effective

Still a bit pricey at 200$; Not very portable due to bulky case

Please note that I am not even anywhere close to being an expert in this field but I really enjoy listening to music of all kinds. here are some of my opinions: Noise Cancellation is on point. when listening to music or watching a movie, it does cancel out my sound souroundings.

I just acquire it secondhand, so I give you my opinion hot no recoil. So far I have mostly used small walkman headphones Philips type

Noise-cancelling headphones have become a must for me on long-haul business trips. Oddly, I find them more helpful when I'm not listening to anything; music or film dialogue effectively drowns out engine noise, but while you're reading, eating or sleeping, then noise cancelling really does its bit.

Very clear and comfortable to wear, great price and product. I would recommend these earphones for travel as they didn't miss a beat very easy to fold away when not in use. Not going to paid Excessive prices - that's the number one reason I purchased this product.

Exactly what I was after - peace within a noisy office environment.

I bought it right before a 5-hour flight. I wore it all along and they fit comfortably. I did feel the urge to lift them from time to time to refresh my ears, but I guess that is normal when you enclose them with something for that long.

Comfortable fit, come with nice carrying case. I am extremely sound sensitive and wear these at work to help block out distracting noises. I like that they are able to cancel some background noise while still able to hear some speech.

Of the models I tested, Bose's QuietComfort 15 reigns supreme in noise-canceling performance and sound quality. I rank the Audio-Technica ATH-ANC9 second overall, though I really like the multiple cancelation modes and the ANC9's ability to function without battery power-features that might make it...

Love these headphones! I can wear them for 9 hours straight at work and they are still super comfortable. Noise cancelling works well and makes music sound even better when it is on. I definitely recommend these to anyone and everyone! Definitely a necessity if you work in an office.
