  • Overview

    With newly designed drivers and in-line mic and control, the ATH-CKS990iS Solid Bass in-ear headphones give you portable, smartphone-compatible headphones with refined bass reproduction. The powerful 13 mm Dual Magnetic-Field Drivers feature an extra magnet in front of the driver to create a concentrated magnetic field that helps produce full, textured bass without distortion. Audio-Technica’s specially designed Multiple-Transition Diaphragms with a diamond-like carbon coating add to the power and precision of the bass, as does the new Dual Bass Venting System, which utilizes two optimally placed vents in each housing for excellent air damping. The housings themselves are constructed of machined aluminum to reduce unwanted resonance and extend mid-to-high frequency response.

    The 1.2 m (3. 9') cable 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-CKS990iS 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.

    Pretty nice earphones


    When i listened it the first time, i was a little disapointed because the bass wasnt that punchy and the high frecuencies was too crispy, but after a using a while i started to apreciate the sound, the bass is solid and clear, the highs and mids started to sound better with the time and i love the desing, they look great. the only bad thing i found is that they are a little uncomfortable for my ears

    Solid punching bass with nice trebles for the price


    A nice solid bass to the eardrums, very punching bass but doesn't compromise trebles be it mid or high. It sounds very well out of the box without burning it in hours of playback. The potential once burned through couple hundred hours is something to look forward to!



    Excellent sound!


    These are excellent headphones for the price. If you are not impressed with the sound at first, try downloading an Equalizer app in your smartphone and play with the sound settings. After doing this, you will see that these headphones are capable of. Nice bass!

  • Q & A

    Hi, I would want to know how long is the warranty on this product.


    The ATH-CKS990iS have a Two-Year Limited End User Warranty.


    Would this pair or the ATH-CKX9iS SonicFuel ear buds be a better for overall true sound quality? I don't want to hear more bass then what's meant to be there. I'd just prefer a more true, quality sound. Which pair would be a better fit?


    Thanks for your inquiry. All of our headphones or earphones that has microphones are wired in CTIA, and most Android phones are also wired in CTIA. So you do not need to worry about that our product will not work with Android devices. If you are looking for good flat quality earphones, I would not recommend the ATH-CKS990iS and the ATH-CKX9iS. I would recommend ATH-LS70iS, they have really good quality of sound, they do not too much of bass and not too much of high, and has a in-line mic.

    Do these headphones have a volume control?


    No, there is not an inline volume attenuator.


    I would like to know if these headphones with the inline remote works with Android phones


    The inline control will play/pause media as well as pickup/hangup phone calls with stock Android and iOS apps.
