  • Overview

    With exclusive Solid Bass dual phase push-pull drivers (12.5 mm x 2), the ATH-CKS1100iS in-ear headphones give you premium sound reproduction with Hi-Res Audio and incredible bass. The specially designed drivers reduce intermodulation distortion for amazing wide-range audio reproduction, from deep, rich bass to crystal-clear high-frequency sounds. Audio-Technica’s new Dual Bass Venting System also contributes to the high-resolution audio reproduction by positioning two vents in each housing for optimal control of diaphragm movement. The housings themselves are constructed of machined aluminum to reduce unwanted resonance and extend mid-to-high frequency response.

    The detachable 1.2 m (3. 9') cable, with newly developed A2DC (Audio Designed Detachable Coaxial) connectors, is comprised of two separate star-quad cables, one dedicated to the left channel, the other to the right, which improves isolation from external noise and channel cross talk. The cable also includes an in-line mic and control that lets you answer calls and control music and video on your smartphone or other portable device. The ATH-CKS1100iS comes with four sizes of silicone eartips (XS/S/M/L) that fit onto the headphones’ two-position posts, supplying a custom fit with outstanding sound isolation. A convenient carrying case is also included.

    These are amazing


    So let me just say this it only falls out if you are moving a lot so don't use them for running or workouts. But lets get to the good part i have been using my Asus rog headset for gaming anyways i had to use my Asus headset cord for something so i couldn't use them so i tried my Audiotechnica earbuds 1100is for gaming and music and the first sounds i heard put a smile on my face these things blew my headphones out of the water. They are so good for earbuds its amazing definitely worth the price.

    With all 5 STAR rating, need I say more? AT should includes FOAM TIP or XL, XXL silicon tips due to the design and weight the could drop off easily. I replaced with FOAM tip and it sit snugly even when i went jogging. All things pros. A good investment or X'mas gift for your love ones. STOP reading, go and get yourself a pair.


    Impressive sound quality but comfort level could be better


    Look for sound quality? Look no further, these bad boys kill it! Classic pop bass all sound awesome. But it'll be better if foam buds are included besides silicon ones, which are not very comfortable compared to how good they sound.



    Amazing Value


    I bought these as well as the Bose Acoustic Noise Cancelling Earphones (for newest ones as of Nov. 2016), which by the way were $50 more than these, and although the Bose had the noise cancellation technology that these lacked, these go deeper into the ear and in effect cancels out more noise than the Bose when the Bose's noise cancellation is turned to off. HOWEVER, what truly surprised me is that, with or without the noise cancellation on, these really deliver solid bass like its naming conferred. And the clarity is very good, too. They honestly sound way better than the Bose I bought to compare. Overall, very satisfied!

  • Q & A

    Is there a 2.5 balanced cable available for these?


    Thank you for your inquiry. Yes, the HDC-212a and the HDC-214A will work.


    Can I able to control volume, take calls using iPod, iPhone.. and also able to control music(start and stop)




    Does the in-line control allow track skipping and /or volume control on Samsung Galaxy Note 5 android cellphone? Do these headphones have any noise-cancelling or noise-isolation features?


    Thank you for your inquiry. The controls should work if you are using the stock music app. There is no active noise cancellation on these.


    The cable of my ATH-CKS1100IS headphone is broken so one side of my headphone does not function. Is their a individual cable for ATH-CKS1100IS I can buy and is there any upgrade cable as well?


    Thank you for your inquiry. Please contact the Parts Department at 330-686-2600 option 4. They will be happy to help with this.


    Couldn't find an appropriate category. Would like to ask if the detachable cable is replaceable if it is damaged.


    Please contact our Service Department at (330) 686-2600 ext 5003 or at for assistance with this.


    Is the microphone quality good enough to use on my PlayStation 4? As you may know about PS4 is that you can directly plug in headphones into the controller to use it as a mic (if it has one on it) and I know many headphones out there that have terrible mic quality over PlayStation network. Specifically iPhone headphones have this very annoying buzz or very high pitched tone that's constantly going off while the user speaks. So what I want to know is that if I were to buy these to use over PSN, would the mic quality be tolerable. You see the reason I'd like to know this rather then just going with a headset is because I find In-Ear Headphones more comfortable and useful. So again, if anyone has an answer, it'd be greatly appreciated. :) thank you for your time.


    Thank you for your inquiry. That is hard to say. The microphone is designed for telephone use and really for gaming.


    Most other headphone manufacturers specify with with smartphones their headphone remote controls are supposed to work and my understanding is no headphones work with both iPhone and Android at the same time. So with which smartphones will the remote controls of this model work?


    The cable included with the ATH-CKS1100iS includes an in-line mic and control that lets you answer calls and control music and video on an Android/iOS smartphone. The control allows you to play/pause music, or answer/hang-up a call. If you have any further questions, please contact the Audio-Technica United States (ATUS) Audio Solutions Team at: Thanks!


    Is 50 ohms a typo? That's to high for most cell phones or portable devices to power. That would definitely require a separate amp? The Japan version has 12ohms and the ckr10 has 12ohms. Also, what does the IS at the end stand for?


    The "iS" means that there is an in-line microphone and controller. The specification listed by Audio-Technica United States is correct; we cannot account for specifications on an import version. 50 Ohm headphones will be fine to use with most current mobile phones and tablets, as the specified impedance would be within proper range. Any "iS" headphone may also be used with a mobile headphone amplifier (like the AT-PHA100), but might lose its in-line functions.
