Freedom to Move

Secure and Comfortable Fit

With one of the longest battery lives available in any truly wireless earbuds, it was important that the CKS5TW feel light in the ear, and are comfortable to wear with a secure fit when moving around. Included with the CKS5TW, you’ll find 8 differently sized earbud silicone tips for a truly customised and comfortable fit, whilst the additional 3D loop provides excellent security. Enjoy up to 15 hours of uninterrupted and comfortable playback with a pocked-sized charging case.

High Quality Truly Wireless Audio

Beautiful Soundscape that Brings the Bass

We wanted to ensure the compact size of the CKS5TW could still celebrate the subtle tones and notes in your favourite music, whilst also bringing out the punchy bass and dynamism of those high-energy workout tracks. With a crystal-clear soundscape, perfected with almost 60 years of Japanese sound engineering, you’ll enjoy detailed and dynamic sound on-the-go - from the timbre of voices in audiobooks to the live reactions of your go-to streamers.

Clear Communications

Qualcomm cVc™ Clear Voice Call Quality

When paired easily with your smartphone or PC/Mac through advanced Bluetooth® 5.0 technology, the CKS5TW wireless earbuds ensure you’re always heard on calls, even in noisy and unpredictable environments. Whether working from home or on-the-go, built-in Qualcomm cVc™ Clear Voice Quality detects background sounds and suppresses them, so that you can always be heard clearly - no clattering of keyboards or doorbells mid-call.
