Headphones — Audio-Technica ATH-CKS50TW2

The ATH-CKS50TW2 is the second-generation update to Audio-Technica's CKS50TW true wireless in-ear, keeping the same bass-forward tuning with a revised playback-time structure. As a direct successor to the CKS50TW, this model likely represents Audio-Technica's incremental refinement of an already well-received platform rather than a wholesale redesign.

Position in line

It sits alongside the CKS50TW in the CKS range, effectively superseding it with the same driver specification but a different battery reporting split between earpiece and case. Buyers should confirm with a dealer whether the original CKS50TW remains in active production alongside this newer model, or whether it has been fully phased out in favour of the TW2 update.

Key specs that matter

Rated response is 5 Hz to 20 kHz with 110 dB sensitivity into 20 ohms, matching the CKS50TW exactly, confirming the shared driver platform between the two generations. Playback time is quoted as 15-25 hours from the earpieces alone, extending to 25-40 hours with the case - a different reporting convention from the original CKS50TW's single 50-hour figure, making direct comparison dependent on how the figures were measured in each case.

Sound and use context

Expect the same bass-forward closed-driver character that defines the CKS range, unchanged from the CKS50TW on the available specification - anyone who has heard and liked the original CKS50TW should find this update delivers essentially the same listening experience.

Pairing

No external amplification is needed - any phone or wireless source drives the 20 ohm, 110 dB specification fully.

Alternatives

The CKS30TW+ is the smaller, shorter-battery-life model in the same range. The original CKS50TW remains available alongside this generation-two update, worth checking current pricing between the two before assuming the newer model is automatically the better value choice. Because both generations of this model may be sold simultaneously by different retailers, checking the exact product listing and packaging carefully before purchase helps avoid confusion between the original CKS50TW and this TW2 update. Overall the practical listening experience should closely match the original CKS50TW despite the different battery reporting.
