  • Overview

    With the ATH-CKR55BT’s newly designed 10.7 mm drivers and Bluetooth® wireless technology (including access to the high-quality aptX and AAC codecs) you get powerful, full-range audio that goes wherever you go. The headphones also feature an in-line mic and controls, allowing you to answer calls, adjust volume and handle playback of music and videos on compatible smartphones and other devices, plus a built-in amplifier to enhance the audio’s depth and resolution. Machined brass stabilizers absorb unwanted vibration for clearer mid and high frequencies.

    The neckband design of the ATH-CKR55BT conveniently situates the in-line mic and controls for easy access and places the battery case on the upper back where, if desired, it can be attached to your shirt collar with the included clip. Also included are four sizes (XS, S, M, L) of interchangeable eartips, 30 cm (11.8") USB charging cable and a protective pouch.

    Available in black (ATH-CKR55BTBK) and blue (ATH-CKR55BTBL).

    Great sound but not for wireless.


    I have been using Audi-technica headphones for more than 4 years. I bought this one after I lost my old headphones. So I wanted to try BT headphone because iPhone does not support headphones jack anymore. The sound is great as I expect from AT, but the frequent is not good. The frequent will drop if it range is more than 2 meters. And sometime it drop without reason. The battery is good enough for daily using if you charge it every night. I don't suggest this headphone for someone who is going using it for running or do exercises. Because the clip is easy to break. And if the clip is broken, it easy to slide from side to side.

    Fragile clip and excessive hiss


    1. Clip is so fragile and it did not last long. 2. Excessive amount of hiss when volume is low 3. Cable is too short to wear comfortably 4. Frequent drop of sounds and statics after several months of light use



    Pretty Good


    Recently bought a pair of the crk-55bt's and so far so good. I'm a college student who really appreciates audio quality and having a good set of Bluetooth earbuds. So far the have pretty good audio quality, but are slightly missing the "fullness" or "depth" that I was expecting, but that could simply be the actual buds I have. I would recommend these to anyone who's looking for a good deal, quality built, and clean everyday earbud. A solid suggestion is to download an external app to tune your earbuds to get the perfect sound you like
