Product Information

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.

While exceptional sound quality may be at their core, Audio-Technica certainly doesn’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-canceling and hear-through functions to block out and hear ambient noise, respectively.

The ATH-CKS50TW wireless earphones work with an array of today’s most advanced codecs, including Qualcomm® aptX™ Adaptive audio, Qualcomm® aptX™ audio, and AAC, ensuring the best sound and performance for a variety of uses. Codecs are selectable through the Audio-Technica Connect app, which also gives you the power to activate the low latency mode, adjust EQ, change L/R volume balance, locate misplaced headphones, and more.

The ATH-CKS50TW earbuds automatically turn on when taken from the charging case and may be used together or as a single earpiece in the left or right ear. The hybrid ear tip structure, fashioned from soft silicone for the ear tip and hard silicone for the sound-delivering shaft, provides a secure, comfortable fit with superior sound performance. Other sound-enhancement features include Qualcomm® cVc™ Generation 8.0 for excellent call quality, sidetone circuitry to let you hear your voice in the headphones for more natural call conversations, and compatibility with Sony’s immersive 360 Reality Audio.

ATH-CKS50TW Wireless In-Ear Headphones
The search for the perfect true wireless earbuds continues. Overall these are solid earbuds. I have tested over 20 brands/models over the last 3 years in search of the perfect buds. The one feature lacking is good battery life. When I saw these had 20 hours and pretty much all the features you could ask for I was hopeful these would be the "perfect" buds. While very solid they are not perfect.

The sound is good but not as great as Anker top end buds or some other way more expensive ones. Solid but didn't blow me away.

The battery life so far I have not ran the battery down and am very pleased with this feature.

The one issue I have had so far is they tend to cut out/static every so often when using to watch TV on my LG OLED using ROKU to stream. This is annoying and at times has me backing up the stream to hear what I missed. I have updated the firmware to the latest and it still does this. Happens about once an hour or maybe a bit more frequently.

The range is not all that great on these either. My other true wireless buds allow me to move around further than these. However, if you don't go more than a room away this is a non issue.

Overall the battery life will have me using these over the other buds I own as I really hate having to switch to another set or wait for them to charge to continue using them.

I have not used them for calls as I find all true wireless earbuds are very lacking in this area, but hey they are little earbuds stuck in your ear, can you really expect great microphone use? Maybe someday but this is lacking in every bud I have tried.
