Dual-driver USB-C in-ear headphones

The jechan CB08-800 combines a balanced armature and a 10 millimetre dynamic coil driver in a brown in-ear shell. A USB-C connector with an integrated DAC and a 3.5 millimetre plug give wired compatibility across phones, laptops and tablets. The 32 ohm impedance suits portable sources without extra amplification. Touch controls on the cable handle playback and calls.

Capacity and headroom

The dual-driver arrangement extends response from 5 Hz to 20 kHz, so sub-bass notes and high harmonics both remain audible. Total harmonic distortion stays low for in-ear use, keeping vocals clean at moderate volumes. At very high output levels the 32 ohm load can draw more current than some phone ports supply, so peak loudness may be limited by the source device.

Thermals noise and power

Passive ear-tip sealing in three sizes blocks roughly 80 percent of ambient sound before any electronics engage. The USB-C plug carries an ENC microphone circuit that suppresses background noise during calls without active noise cancellation on the earpieces themselves. No battery is required; the headphones draw all power from the host port and remain cool during extended listening.

Questions about this item

Will the USB-C DAC work with my older phone that only has a 3.5 mm jack?

The earbuds include both a USB-C connector and a 3.5 mm plug, so you can use the 3.5 mm connection directly with your phone without the USB-C adapter.

How can I confirm the ENC microphone is cancelling background noise during a call?

Make a test call in a noisy environment; the built-in ENC function in the USB-C plug should suppress ambient sound so the other party hears your voice clearly.

Which ear-tip sizes are included and do I need to buy any cables separately?

The box contains replaceable soft ear tips in three sizes — S, M and L — and both the USB-C and 3.5 mm connectors are integrated, so no extra cables are required.
