Audio-Technica ATH-CKD30C - Black - White

Description

Direct USB-C connection and built-in DAC

Wired listening eliminates the friction of pairing routines and battery dependency. The ATH-CKD30C plugs directly into the USB-C port of a smartphone, tablet or computer. The raw digital signal is handled by a digital-to-analog converter built into the connector, natively decoding files up to 24-bit / 96 kHz. This onboard conversion ensures a lossless audio transmission from source to driver, without relying on the variable quality of the host device's integrated audio circuits.

10 mm wide-band dynamic drivers

Sound reproduction is anchored by two 10 mm dynamic drivers delivering an extended frequency response from 5 Hz to 25,000 Hz with a low 17 Ω impedance. This combination enables detailed reproduction across the entire audible spectrum, from deep bass to airy treble, while remaining very easy to drive directly from the host device's USB-C port without external amplification..

Omnidirectional microphone for clear calls

The control module houses an omnidirectional MEMS condenser microphone. Capturing the voice with a sensitivity of −42 dB, it provides clear transmission during meetings, phone calls and video conferences. Pairing this microphone with the Clear Voice EQ mode optimizes conversation intelligibility without requiring any software configuration on the host computer or phone.

Tangle-resistant cable and hygienic comfort

The 1.2 m Y-type cable combines a tangle-resistant wave texture with a soft fabric-wrapped finish to prevent knots in a bag or pocket. The lightweight housings (about 5 g each) sit discreetly in the ear canal, providing passive acoustic isolation that limits sound leakage on the go. Four sizes of silicone eartips with antibacterial treatment (XS, S, M, L, M pre-installed) maintain hygiene and secure the fit for every ear canal. 

Frequently Asked Questions (FAQ)

Are they compatible with laptop and desktop computers?

Yes, they operate universally. The USB-C connection is supported by Mac and Windows systems without requiring additional drivers. The in-line remote with omnidirectional microphone handles calls and video conferences, and the Clear Voice mode optimizes vocal intelligibility.

Do they work with recent iPhones and iPads?

Yes, with models that have a USB-C port (iPhone 15 and later, USB-C iPad) without adapter or driver. On older iPhones with a Lightning port, a USB-C to Lightning adapter (not included) would be required, but we recommend a native Lightning-plug model for those devices instead.

How does sound mode selection work?

The sound profile is changed directly from the in-line remote. You can instantly toggle between Bass Boost mode, designed to maximize bass impact for music and movies, and Clear Voice mode, optimized for voice communication. No app required: the profile is processed by the DAC built into the earphones.

Do they need to be charged?

No. That's one of the main advantages of this form factor: the ATH-CKD30C contain no battery and draw the very low power needed to operate directly from the host device's USB-C port. No charging, no battery life to manage, no battery degradation over time.
