USB-C Wired In-Ear Earbuds with Mic

The Koajim BASS 710C connects directly to USB-C smartphones, tablets and laptops without Bluetooth, batteries or adapters. Dual 6mm dynamic drivers and a high-performance DAC chip deliver lossless audio up to 24-bit/192kHz resolution. An inline remote handles playback and calls without touching the device.

Sound isolation and lightweight build

Ergonomic design with self-adapting ear fins and 45A silicone tips in three sizes forms a seal that isolates ambient noise effectively. The bulletproof fibre core cable adds flexibility and durability while the aluminium alloy casing protects the plug. Total weight is 20 grams for extended comfort.

What the accessories and controls change

Three tip sizes let most users secure a stable fit, though very small ear canals may not suit the design. The push-button remote provides hands-free mic use for calls and voice commands with 16-ohm microphone impedance and 40Hz-20kHz response. A user manual is included for setup guidance.

Questions about this item

How do I install the Koajim BASS 710C earbuds and which step do people often miss?

Plug the USB-C connector directly into your device; the step many skip is selecting the correct silicone tip size from the three included to achieve a proper seal for sound isolation.

What maintenance or replacement will the Koajim BASS 710C earbuds need over time?

The 45A silicone ear tips in three sizes are the only wear items; replace them when they lose elasticity or no longer seal, and clean the 6 mm driver meshes if debris builds up.

What limit appears first during sustained high-volume use of the Koajim BASS 710C earbuds?

The 16-ohm impedance combined with 106 dB/mW sensitivity means the earbuds reach high output at low source voltage; prolonged maximum volume can overdrive the dual 6 mm dynamic drivers.
