Audio-Technica ATH-CKS50TW Wireless Earbuds Headphones

Unlike many companies that produce truly wireless headphones, Audio-Technica places an emphasis on sound quality, not just convenience. The ATH-CKS50TW earphones are no exception. Featuring specially designed 9 mm drivers, these earbuds deliver clear, full-range audio with deep, powerful bass – low frequency is enhanced by acoustic ducts on the back of the drivers.

But while exceptional sound quality may be at their core, we certainly don’t skimp on the convenience, either. For starters, the ATH-CKS50TW earbuds provide best-in-class battery life, with up to 20 hours of continuous use on a full charge. There’s also a fast-charge option that gives you roughly 90 minutes of use from a quick, 10-minute charge. The multifunction buttons on each earbud let you easily control music playback, volume and calls, plus select noise-cancelling and hear-through functions to block out and hear ambient noise, respectively.

Make your voice heard with Qualcomm® cVc™ Generation 8.0

Enjoy improved microphone performance in calls, whether in the office, working from home or in an online class. The sidetone function of the CKS50TW also allows you to hear your own voice during calls for more natural-sounding conversations, feeling almost as if you weren’t wearing headphones at all.

Built-in button design for on-the-go operation

Audio-Technica’s ATH-CKS50TW wireless earbuds are designed for reliable, stress-free operation for a more enjoyable truly wireless listening experience. The left button adjusts the volume and switches between hear-through and noise-cancelling functions, while the right button lets you easily start/stop playback, skip between songs, or enable quick hear-through.

Rain and splash-proof design

The CKS50TW wireless earbuds boast an IPX4*-equivalent JIS protection rating. The splash-proof design means you never have to worry about keeping your truly wireless earbuds dry in sudden rain showers or when exercising.

*An IPX4-equivalent rating signifies the product will not be adversely affected by water splashing from any direction. This rating does not ensure protection in hot and humid locations such as baths and showers. The product is not completely waterproof.

Greater customization

Personalize the operation of your Audio-Technica earbuds via Audio-Technica’s Connect app, available from both Apple and Google Play. Take full control of your sound, switching between codecs, experimenting with equalizer pre-sets or adjusting your volume levels. You can even use the app to help locate your earbuds, so you’ll always have a stunning soundscape to accompany your day to day.

Interruption-free listening

Packed full of useful functions, the CKS50TW earbuds are compact, with a unique antenna structure designed to ensure stable connectivity while fitting in limited space. This helps prevent sound from being interrupted even in train stations or other crowded locations.

The ATH-CKS50TW earbuds also feature Qualcomm® TrueWireless Mirroring.

Independent transmission to the left and right sides reduces sound interruptions and delays for videos on all devices, including Android and iOS smartphones.

Automatic power-on and fast pair convenience

Once paired with your device, Audio-Technica’s CKS50TW wireless headphones automatically turn on and connect to your Android or Google device** when they are removed from the case for quick usability. When the truly wireless earbuds are put back in the case, they power down and begin charging. The power can also be turned on/off directly from the headphones.

** Only one Android device can be paired by using Fast Pair. Google and Android are trademarks of Google LLC.

Check up on your charge with LED indicators

The CKS50TW’s four LED indicators light up or flash whenever the charging case is opened or closed, so the user can see the charging status or remaining charging case battery power at a glance.

Sony’s 360 Reality Audio certified

The combination of 360 Reality Audio and Audio-Technica’s long-cultivated acoustic technology allows listeners to fully experience the world of sound envisioned by the creators.

A perpetual quest for superior sound
A Revolutionary Music Experience

The newly developed large-diameter drivers (9mm Solid Bass HD TWS drivers) deliver deep, powerful bass while the CKS50TW shape provides a secure and comfortable fit – an important factor for truly wireless headphones. The airtight fit prevents the bass from escaping to deliver a unique and intimate music experience.

Best-in-class Battery Life
Up to 20 hours* of Power on a Single Charge

Using the ATH-CKS50TW earbuds with the charging case allows for as much as 50 hours of playback (20 hours in the earbuds + an additional 30 hours with the charging case)**, so you can enjoy 1.5 hours of music every day for a whole month without needing to recharge. Plus, gain 90 minutes of power from just 10 minutes of charge time.

* As of September 2021 according to in-house figures, with noise-cancelling disabled. Playback for around 15 hours is possible with noise-cancelling enabled. Results may vary depending on usage conditions.

** Results may vary depending on usage conditions.

Get lost in music
Noise-Cancelling Mode

Simply press the built-in button on the left earbud or activate noise-cancelling via the Audio-Technica Connect App. A handy hear-through function can be activated with one tap of the button on the right earbud, for a momentary return to your surrounding environment before getting lost in music again.

Long-lasting comfort
Innovative, Comfortable, Earbud Design

The newly developed earbud design ensures a secure and stable fit that prevents the earbuds from falling out of the ears, even during intensive workouts. CKS50TW comes with four pairs of soft silicone eartips, allowing for a deeper audio performance and superior, long-lasting comfort.

Audio-sync for gaming
Minimise Audio Lag with Low Latency Mode

Enjoy a more immersive experience with minimal sound delay while playing games or watching videos on your smartphone or tablet with Low Latency Mode.

*Low Latency Mode can also be turned on/off from the Connect app. Bluetooth® connections may be affected by obstacles and ambient radio wave conditions.

Connect Simultaneously to Multiple Devices
Multi-point Support for Two Simultaneous Bluetooth® Connections
