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.
