Audio-Technica ATH-CKS50TW2 True Wireless Bluetooth Noise-Cancelling In-Ear Earphone with Mic - Beige

Ultra-Portable Headphones—Leave the Case at Home  

New Magnetic Switch™️ (PAT.P) feature preserves power on the move  

The headphones can be connected via a magnet when you’re out of the house, enabling you to turn them OFF without placing them back in their case. This makes it easier to preserve power and saves space, as you can store the connected headphones without a case when out of the house.  

Thanks to the long-lasting battery life, the headphones can be used on the move all day on one charge.   

Best-in-Class*1 Battery That Can Be Used All Day Long  

Long-lasting battery with up to 25 hours*2 of continuous playback  

With noise-cancelling turned off, the headphones alone can provide continuous playback for up to 25 hours*2 so you can enjoy music, videos, and calls all day long without worrying about running out of battery. Even with noise-cancelling turned on, you will get up to 15 hours of continuous playback, and up to 65 hours*2 of continuous playback with the charging case.  

*1 As of October 2024 according to in-house figures. Based on use of headphones only with noise-cancelling disabled.  

*2 When playing music. Results may vary depending on usage conditions.  

Place-and-charge Qi wireless charging  

To charge the headphones, simply place the charging case on a Qi wireless charger (sold separately). Or charge it by connecting the included USB charging cable.　  

• The Qi mark is a trademark of the Wireless Power Consortium.  

Fast-charging support  

Charging for just 5 minutes (approx.) provides about 90 minutes of use (with noise-cancelling turned OFF).* Simply place the headphones in the case for a quick charge before you head out.  

*Results may vary depending on usage conditions.  

Heavy Bass Sound + Noise-Cancelling to Immerse Yourself in Music  

Deep bass from 9 mm SOLID BASS HD TWS drivers  

The large-diameter drivers deliver deep, powerful bass while ensuring a comfortable fit—an important factor for truly wireless headphones. The airtight fit prevents the bass from escaping and, combined with the high-precision hybrid noise-cancelling function, you can enjoy your favorite music to your heart’s content.  

Hybrid digital noise-cancelling technology to create your very own sound space*  

The noise-cancelling function, which allows you to be immersed in music and to enjoy bass even in noisy places, has been further enhanced. Combined with an excellent fit, you can immerse yourself in music no matter where you are.  

Two small noise-cancelling MEMS microphones* on each of the headphones capture environmental noise for high-accuracy digital signal processing with proprietary filters, maximizing noise-cancelling performance and eliminating unwanted noises.  

*Two microphones are located on the inner and outer sections of the headphones to detect ambient noise. This technology uses integrated feedforward and feedback systems for high-precision processing to cancel noise.  

Acoustic ducts for rich low-frequency sounds  

Ducts on the back of the drivers control airflow to create a detailed acoustic space. This design allows for ideal movement of the drivers to deliver rich low-frequency sounds.  

Hear Only the Sounds You Want  

Listen to music while maintaining awareness of your surroundings*  

The hear-through function is useful for listening to music while walking, playing sports, doing housework, working remotely, or using public transportation.  

*Use the Connect app to switch between the two environmental sound capture levels.  

Easy capture of voices with talk-through function*  

The talk-through function is perfect for tuning in or out of your surroundings by allowing you to hear announcements or listen to those around you.  

*Use the Connect app to customize the talk-through background volume level.  

Speak Naturally, as Usual  

Noise-reduction function for clear calls  

Crystal-clear hands-free calls with one or both headphones. The noise-reduction function clearly delivers just your voice to the other party during online meetings and calls. Unnecessary noise is eliminated to ensure smooth communication. Optimal microphone placement also suppresses noise (wind noise), allowing you to talk comfortably indoors or out.  

Beamforming microphone clearly captures voices, even in noisy environments  

Small, high-performance MEMS (micro-electromechanical systems) microphones are strategically placed in two locations on each headphone. These two microphones use beamforming technology* for clear transmission of your voice even in noisy environments.  

*This technology allows for directional capture toward the speaker’s mouth for enhanced call quality.  

In-call noise-cancelling and hear-through for improved clarity in any situation  

Just as with music playback, the noise-cancelling and hear-through functions can be turned on or off during calls to suit any environment and situation.  

Up to 10 hours of continuous calling time, even for all-day online meetings  

Up to 10 hours of talk time with noise-cancelling disabled.* Use even during long online meetings, without having to worry about battery power.  

*Results may vary depending on usage conditions.  

Waterproof and Dustproof  

Washable waterproof and dustproof performance lets you enjoy bass anywhere  

JIS/IEC protection rating: IP55-equivalent (headphones only).* The headphones are highly waterproof so you can safely use them almost anywhere in your daily life, and they are dustproof so you can use them in environments with dust and sand. You don’t need to worry about getting them wet in the rain or if you sweat when exercising. They can be rinsed off with water when you’re finished using them.  

*IP5X rating indicates protection against dust that can interfere with functions. IPX5 rating indicates protection against water jets. This rating does not ensure protection in hot and humid locations such as baths and showers. The product is not completely waterproof. The main body of the headphones is waterproof and dustproof equivalent to IP55, except for the openings where sound comes out.  

Solid, Stable Construction  

Headphone design that keeps the bass intact  

The tragus hold design avoids the protrusion (tragus) outside of the ear canal and allows the headphones to be worn naturally, maintaining a strong hold. The headphones fit snugly in the ear to prevent gaps, keeping bass from escaping.  

Hybrid eartip structure combining hard and soft silicone material  

The headphones’ eartips are soft and pliable for a gentle fit. Meanwhile, the parts of the shaft that transmit sound are stiff to reduce adverse impacts on sound quality and noise-cancelling. The hybrid structure utilizes the varying hardness of the two silicone materials to create a comfortable fit with superior sound performance.  

The tactile umbrella fits naturally in the ear canal for enhanced airtightness, an essential factor for the noise-cancelling function. The high-strength shaft also minimizes sound transmission loss to bring detailed audio directly to the eardrum.  

App Enhanced for Better Enjoyment  

Enrich your daily life with the dedicated Connect app  

Soundscape function for improved focus or relaxation  

Use the Connect app to listen to the relaxing sounds of nature carefully recorded using Audio-Technica microphones and designed to promote relaxation and calmness, or use masking noise to enhance concentration and healing sounds for rejuvenation and meditation. This function offers soothing mental soundscapes.  

Advanced personal time management with Private Timer function  

The Private Timer function ensures that notifications are only heard by the person wearing the headphones. The headphones can also be used to help manage your time during work or when taking a break with a quick nap.  

Out of Range Alert to prevent headphone loss  

The Out of Range Alert notifies you when the Bluetooth® connection signal is weak, so you’ll know you’re getting too far away from the headphones before the connection is lost.  

Product Locator displays a map showing where the headphones are located  

The last location where the headphones were disconnected from your Bluetooth® device is displayed on a map in the Connect app. You can explore possible locations where you may have lost your headphones.  

Other Convenient Features  

Multipoint support for two simultaneous Bluetooth® connections  

You can connect to both your smartphone and computer or tablet at the same time, so you’ll never need to worry about switching Bluetooth® devices again. Respond immediately to incoming calls on your smartphone while enjoying videos on your tablet without having to reconnect.
