  • 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.
