Audio-Technica ATH-CKS50TW Wireless In-Ear Headphones

A pair of true wireless buds that don't skimp on acoustics, Audio-Technica ATH-CKS50TW earphones deliver balanced sound with plenty of low-end punch.

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 response is enhanced by acoustic ducts on the back of the drivers.

But 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-cancelling 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 read more in the left or right ear. The hybrid eartip structure, fashioned from soft silicone for the eartip 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.
