Driver: 10mm. Impedance: 32Ω. Sensitivity: 92dB. Frequency response: 20Hz–20kHz. Microphone sensitivity: -48±3dB. Cable length: 1.2m. The in-ear design uses a 45° angled fit. Source copy describes the earphones as sweat and splash resistant — no IP or IPX rating is provided in source documentation. No certifications listed. Package: earphones, three pairs of eartips (S, M, L), and English and Chinese user manual. Colour: Black.

The 10mm moving coil driver delivers output across a 20Hz–20kHz frequency range with a sensitivity of 92dB at 32Ω impedance. The built-in microphone (-48±3dB) supports hands-free calls from the cable. The 45° angled in-ear design positions the driver to direct sound into the ear canal while the eartip provides a fitted seal — three eartip sizes (S, M, L) are included to allow adjustment. The aluminium alloy housing and TPE cable form the 1.2m wired design. Source copy describes the earphones as sweat and splash resistant — no IP or IPX rating is provided in source documentation, so a specific waterproof protection level cannot be confirmed. No certifications are listed in source.

The 10mm driver size is standard for wired in-ear earphones and covers the full audible spectrum. At 32Ω impedance, the earphones are compatible with most Type-C devices without requiring a dedicated amplifier. The fitted eartip seal reduces ambient sound reaching the ear through passive isolation — this is a mechanical property of the in-ear form factor, not an active noise cancellation (ANC) function.\u003c\/p\u003e\n\u003ch4\u003eType-C connector — 1.2m cable — aluminium alloy + TPE\u003c\/h4\u003e\n\u003cp\u003eThe Type-C plug connects directly to compatible devices with a standard Type-C audio port. Note that some devices route USB-C audio digitally — analogue audio via Type-C requires the device to have a built-in DAC that supports analogue audio output over the Type-C port; confirm your device's Type-C audio compatibility before purchase. The 1.2m cable is suited to in-pocket use with a device in a jacket or bag pocket. The aluminium alloy housing provides structural rigidity at the driver capsule; the TPE cable sheath provides flexibility and resistance to flexion wear.\u003c\/p\u003e\n\u003ch4\u003eBuilt-in microphone — 45° in-ear design — three eartip sizes\u003c\/h4\u003e\n\u003cp\u003eThe built-in microphone (sensitivity: -48±3dB) is positioned in-line on the cable for hands-free calls. Source copy describes \"intelligent noise reduction\" for the microphone — the earphones are wired and do not contain an ANC chip; this describes the microphone's passive in-line design which positions the capsule away from the speaker driver to reduce driver output entering the mic during calls. The 45° angled in-ear fit directs the driver towards the ear canal and positions the eartip for a stable, conforming seal. Three pairs of eartips (S, M, L) are included — select the size that best seals the ear canal for a secure fit.\u003c\/p\u003e\n\n\u003ch3\u003eBest for\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eType-C wired listening — direct plug-in to compatible smartphones and laptops\u003c\/li\u003e\n  \u003cli\u003eHands-free calls — built-in microphone at -48±3dB\u003c\/li\u003e\n  \u003cli\u003eIn-ear passive isolation — angled 45° fit with fitted eartip seal\u003c\/li\u003e\n  \u003cli\u003eMulti-fit use — three eartip sizes (S, M, L) for different ear shapes\u003c\/li\u003e\n  \u003cli\u003eCompact wired audio — aluminium alloy build, 1.2m cable, Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × USAMS EP-43 Earphones (Type-C, 1.2m)\u003c\/li\u003e\n  \u003cli\u003e2 × Small eartips (S)\u003c\/li\u003e\n  \u003cli\u003e2 × Medium eartips (M)\u003c\/li\u003e\n  \u003cli\u003e2 × Large eartips (L)\u003c\/li\u003e\n  \u003cli\u003e1 × English and Chinese User Manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility and setup\u003c\/h3\u003e\n\u003cp\u003eMaterial: Aluminium alloy + TPE.
