    Overall the headphones are an improvement over non-cancelling headphones. The buzz when the music is off can be annoying. This makes it difficult to listen to music and voice over when using the headphones. These headphones are for just listening to music; we bought these just for music. I am disappointed that the cable is not a universal one; this alone will make my next purchase for a better headphone, one that can replace the wear and tear components. Overall the headphones work very well for the value, 1/3 the cost of retail. For the retail cost of the headphones, the cord could have been more robust, 1/8 jack both ends, and lightweight at the same time. I have a pair of headphones, non-noise cancelling, bluetooth, that I like much better for fit, sound and quality build for the same retail price.



    Good Product, Great Service


    Great product, while it worked. They stopped working about 6 months after buying them and it ended up being a problem with the cord. After a quick talk to the service department they sent a new cord completely free. After attaching the new cord they work perfectly again.

    Exceptional Sound AND Noise Cancellation


    I purchased a pair of ATNC27s approximately 20 months ago and they are still going strong! I have not had any issues with the cord( as you may read in other reviews ) but as it is very thin I take extreme care not yank or snag when in use. I keep it wound around the phones when not in use. Music/Sound: These headphones sound very good with any genre of music. I have listened to Choral-Polyphonic Classical to Hardcore Electronic Dance music, Acoustic( Flamenco Guitar for example), Pop-Rock, Metal, Big Band, Swing, Cinema Soundtrack, Piano( Baroque to American AM Radio Standards) and etc. The point being these headphones are suitable for all Music Tastes. In my opinion there is a SLIGHT Bass Boost but I must stress it does not adversely affect the Middle Range and Treble(High) parts of the Music. Note: If Active Noise Cancellation is engaged when listening to music--it serves to slightly amplify the sound. This said, I usually listen with it off unless blocking unwanted noise. Either way the headphones sound very good. Noise Cancellation: Excellent to Superior. My litmus test is not air plane engines but listening in a laundromat with 10 or MORE SpeedQueen Washers and Dryers running simultaneously in Spin Cycle. When this occurs the floor literally shakes. I am serious! The Noise Cancellation reduces that level of noise to a barely audible and very remote sounding whisper esp when used with music yet I can feel the floor vibrating. Sometimes, I take them off to sample the ambient noise level and after nearly 2 years I an still astounded at the amount of noise/sound reduction. Wear and Tear: I take care of my headphones. I do not throw them around , sit on them or handle them roughly. This said they have fallen on a hard wood floor on a couple of occasions and suffered no damage. I sometimes carry them in my backpack and are jostled and bumped. No harm has been done. The ear pads look as they did when the set was brand new. Point being, take of the headphones and they will last and perform well. Summary: Simply Very Good Headphones. Good Sound. Good Noise reduction. I am satisfied.

    Great set, better Noise Cancelation than SOUL!


    I love these! My big issue is the cord, it's rather stiff & not a universal size. The ends are different sizes. The cord broke after 6 months of constant use the cord broke inside somewhere. I started using my husband's SOUL noise Cancelation Headphones & they don't work at all compared to this set! I need to purchase the cord again, I just hope it's a better quality one. Great on blocking noise once turned on! The ear piece could be bigger but over all worth the $$

  • Q & A

    Can you use the headphones while noise cancellation is off to not use battery?




    can ath-anc33 be linked to fm radio


    You may connect to any standard headphone output connection.


    How do you replace the battery... When i turn on the headphones the small light is red does that mean the battery needs to be replaced


    Please see instructions for replacing the battery in the manual:

    On a recent United Airlines flight my wife's ATH-ANC27x headphones only had one active audio channel. My ATH-ANC33iS earbuds worked perfectly in the same audio jack. Her ATH-ANC27x headphones have a 3 conductor plug (TRS?), whereas my ATH-ANC33iS has a four conductor plug (TRRS?). I assume that for headphones to work I probably need an adapter that has a TRS jack to a TRRS plug. Is this correct. Do you sell one?

    Thank you fro your inquiry. I was not aware of airlines using the TRRS connector. Please verify that her headphones work on other devices. Even plugging into a TRRS input the headphone portion should still line up and work.


    Is there anyway to purchase the headphone cord separately and if so where can I buy it?

    Thank you for your inquiry. You may contact our Parts Department at or call (330) 686-2600 ext 5002. to inquire about a replacement if you are located in the US.


    Does this model come with a microphone to make calls? If not, which of your over the ear, active noise cancelling headphones are wired (not Bluetooth) and use AAA batteries instead of rechargeable batteries and come with a microphone? These are the most important things I am looking for. Thanks. BL


    Thank you for your inquiry. No this model does not. You will want to look into these models: ATH-ANC9, ATH-ANC70, ATH-ANC50is. The ANC9 and ANC50iS have inline cables and the ANC70 have the controls in the left ear cup.


    I purchased the headphones last month from Amazon, for my long haul flight. As I took it out to use, the ear left ear ear cover snapped inside the swivel connector. I am pretty disappointed that this product is so fragile. Unfortunately I was out of the country for over a month and cannot return this back to Amazon. I want to find out if there is any way the warranty covers this failure. Thanks

    I recently purchases quiet point ATH-ANC27 noise cancelling headphones and they work great!! However they are too tight even after adjusting them to their largest setting and are giving me a headache due to the pressure they are putting on my head. Do you make larger sizes? and if so how do I order one?
