Audio-Technica ATH-ANC9 QuietPoint Noise-Cancelling Headphones

Audio-Technica's ATH-ANC9 QuietPoint® headphones use proprietary active noise-canceling technology to provide a comfortable listening environment in areas with high ambient noise. Delivering noise cancellation up to a remarkable 95%, the ATH-ANC9 QuietPoint® headphones feature Audio-Technica's new Tri-Level Cancellation™. Mode 1, ideal for use on airplanes, trains and buses, applies maximum noise cancellation to low frequencies. Mode 2, designed especially for use in noisy offices or crowded places, targets the mid-range frequencies, while Mode 3 creates a pristine, peaceful environment ideal for study.

The headphones feature four miniature microphones, two in each earpiece, that pick up ambient noise and create a sound-canceling signal to effectively block the noise. The ATH-ANC9 headphones also offer a cable with an inline microphone and controller for answering calls and controlling music. The mic and controller support select products, including iPhones, iPads, and many iPods. The microphone has an omnidirectional pickup pattern and it is designed for crisp intelligibility, so your voice will be clearly transmitted without having to speak directly into the mic.

These headphones are designed to offer you crystal-clear sound that makes Audio-Technica the choice of leading artists worldwide. Wherever you happen to find yourself - in the comfort of your living room, in a noisy office, or settling in for a long flight - there is no better way to experience audio or immerse yourself in a peaceful environment.

4 out of 5 eggs

Pros: -Great noise cancelling, audio quality, and bass
-Very nice build quality considering the all-plastic construction
-Comfortable! I have worn these non-stop on over a dozen 8-10 hour flights and never had any aches or strains. I also have a big head (7-1/2)
-Nice carrying case and all the accessories you'd ever need are included
-Good battery life, maybe 20-24 hours on regular alkalines

Cons: -The included cords are kind of squirrely and have too much memory.
-The mic cord was $20 to replace from the factory after my cat ate it, but as a major plus the accessories include the non-mic cord as a spare so if you're on a trip there's a backup
-The power switch is loose so I have had to send them in for a warranty repair. Funcionality wasn't impacted but for a $200+ set of headphones it should be right.

Other Thoughts: The flimsy cord is the only conceivable setback of these headphones, in all other respects they are top notch. Get these and skip the Blose

3 out of 5 eggsCan't recommend

Pros: 3 modes of noise cancellation, for whatever that's worth.

Cons: pretty flat sound.

Other Thoughts: I really wanted to like these headphones! I had some of the anc7's ~4 years ago, and loved them! They were half the price of the b0se noise-cancelling headphones, and I figured the anc9's must be amazing; so much so that I returned the B0se phones that I had bought 3 weeks earlier. Turns out that was a poor decision. These phones have very poor bass response compared to the b0se ones, and are quite bulky. If you want a good product, and want to save money, go with the ANC7's, but if you're going to spend three hundred dollars, go with the B0se model.
