USB-C In-Ear Earbuds for Wired Listening

These USB-C wired in-ear earbuds connect directly to smartphones, tablets and laptops without Bluetooth, batteries or adapters. Dual 6mm dynamic drivers and a built-in DAC deliver lossless audio up to 24-bit/192kHz with a frequency response of 5Hz-40kHz. An inline microphone and push-button remote handle calls and playback control. The aluminium alloy plug and bulletproof fibre cable add durability.

Fits USB-C Devices with Plug-and-Play Simplicity

No separate DAC, amplifier or power source is required; the earbuds draw power and signal from the host USB-C port. Sound-isolating ear fins and three sizes of 45A silicone tips create a seal that blocks ambient noise. The package includes a user manual but no carry case, replacement cable or desktop stand, so users supply their own storage. Buyers whose devices lack a USB-C port cannot use this product.

Accessories Enable Fit and Immediate Use

Three pairs of eartips let each listener choose the seal that suits their ear canal, though the design may not suit very small canals. The tangle-free cable and inline remote free the user from touching the connected device during calls or track changes. No software installation, companion app or firmware updater is bundled, so the experience remains purely hardware-driven.

Questions about this item

How long can I listen before the inline controls or microphone stop responding during a full-day session?

The earphones draw power directly from the USB-C port with no internal battery, so the controls and microphone remain active as long as the host device supplies power.

Do the earphones get warm or produce audible hiss after several hours of continuous playback?

Passive dynamic drivers and the integrated DAC run cool; no active noise-cancelling circuitry means there is no fan or pump noise, and the 106 dB signal-to-noise ratio keeps background hiss inaudible.

Which devices can I plug these straight into without an extra adapter or driver install?

Any smartphone, tablet or laptop with a USB-C port that supports digital audio output works immediately — no Bluetooth pairing, batteries or separate DAC required.
