Product Information

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.

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!

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
