IMPORTANT SAFETY RECALL

There has been a recall issued on the ATH-CK3TW charging case. Please see here for more information.

The Consumer Product Safety Commission press release pdf can be seen here.

The ATH-CK3TW truly wireless in-ear headphones with Bluetooth® 5.0 technology are ready to go whenever – and wherever – you are, empowering you to “explore and connect.” Remove them from their small, portable charging case and they automatically turn on. Put them back in the case and they turn off and start charging. The headphones are even equipped with smart sensors that detect when you remove the headphones from ears and when you put them back in, automatically pausing and playing the audio again so you never miss a beat.

The headphones are equipped with specially designed 5.8 mm drivers that reproduce powerful, detailed audio from an ultra-compact design. These ergonomic, minimalist earbuds fit naturally in ears of all sizes and come with four sizes of thin, flexible silicone eartips (XS/S/M/L) that further customize the fit, providing excellent isolation and improved sound delivery.

The compact earbud housings include a built-in mic and touch controls that are easy to find with the fingertip, making management of your music and phone calls a snap. Call quality is greatly improved by Qualcomm cVc™ (Clear Voice Capture) technology. Call audio also plays in both headphones, making conversations even clearer.

The headphones have an IPX2 water-resistance rating, which means they are protected from dripping water, such as rain and sweat. They are compatible with the high-quality Qualcomm® aptXTM audio codec and with Qualcomm TrueWireless™ Stereo Plus, a special low-latency function that allows you to stream the latest releases with no audio disruption and a stable connection.*

The ATH-CK3TW earbuds offer six hours of continuous use on a full charge, with 24 hours of additional power available from the charging case. Both the earbuds and the charging case have LED indicators to display the charging status, and the charging case is equipped with a USB-C battery jack to improve charging time.

Available in black (ATH-CK3TWBK), blue (ATH-CK3TWBL), and white (ATH-CK3TWWH).

*Requires a smartphone/device that is compatible with Qualcomm TrueWireless Stereo Plus functionality. Qualcomm TrueWireless is a product of Qualcomm Technologies, Inc. and/or its subsidiaries.
