  • Overview

    The ATH-CKS55XBT takes the Solid Bass experience wireless. Featuring Bluetooth® wireless technology along with an in-line mic and controls, the ATH-CKS55XBT lets you answer calls, adjust volume and handle playback (play, pause, fast-forward and rewind) of music and video on compatible smartphones and other portable devices. The headphones remember up to eight devices and automatically connect with the last paired device.

    Like the other in-ear Solid Bass models, the ATH-CKS55XBT features Audio-Technica's direct-diaphragm driver design for increased fidelity and dynamic impact. The headphones also incorporate a high-quality headphone amplifier along with Audio-Technica’s innovative Double Air Chamber System, which focuses the natural airflow produced by the driver movement to expand its bass output. The result is expansive, rich bass that doesn’t sacrifice mids and highs.

    The ATH-CKS55XBT is equipped with an internal lithium polymer rechargeable battery that provides five hours of continuous use and up to 200 hours in standby mode. A 1.0 m (3.3') USB charging cable is included. The ATH-CKS55XBT also comes with four sizes (XS, S, M, L) of interchangeable silicone eartips to ensure a custom fit, and the unique two-position post on each headphone lets you position the eartips for better sound isolation.

    In my top 5 headphones.


    Very good overall headphone. Great feel. Very stylish. Great battery life and charge time. After about 7 months of use the wire on each headphone started loosning and sound would cut out. Used mainly on bus rides and during school. Only complaint.



    Highly recommend


    I generally use the product while cutting the grass or even while exercising. The sound is superb!!

    How to get this earphones? I cannot buy it on this website right now.

    What do I do if my headphones won't charge


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


    How can I sync with a MacBook? All Apple documentation says to check the documentation that comes with your wireless headphones. :(


    See page 8 of the manual.


    Hello. I'd like to know which country they are manufactured in.

    Vlad the newbie

    These headphones are made in China.


    Are they sweatproof?


    These ones are not sweat-proof. You are looking for our SPORT Series.


    One issue I've had with several Bluetooth headsets is a 1-2 second sync delay on sound when watching videos or movies. Does this headset (or other A-T models) have technology that manages or eliminates this issue?


    The latency (delay) is standard with any analog to digital (or vise versa) system. The delay is inherent with the Bluetooth technology. Additional helpful information here:


    Are these compatible with a windows phone?


    Provided that your Windows Phone supports a Bluetooth audio connection (most Windows phones do), then it should work fine! If you have any further questions, please contact the Audio-Technica United States (ATUS) Audio Solutions Team at: Thanks!


    Are they waterproof?


    No, the headphones are not waterproof.


    Does this model allow control volume or pause playing track on iPod (nano) which is not Bluetooth?


    The controls are controlled via Bluetooth.
