Letshuoer S12 In-Ear Headphones Silver — 14.8mm Planar Driver, Detachable 3.5mm Cable

Letshuoer S12 are wired in‑ear headphones with a 14.8mm planar magnetic driver built to deliver high-resolution detail, controlled bass, and effortless volume from phones, tablets, and PCs.

The Letshuoer S12 pairs a large planar magnetic diaphragm with a precisely machined aluminum chassis and an ergonomic shell to offer comfortable, portable high‑fidelity listening. With high sensitivity and a detachable silver‑plated cable, the S12 is designed to be easy to drive from both mobile devices and dedicated DAC/amp setups, while the included tips and vents help maintain comfort during extended sessions.

How does the 14.8mm planar driver change the sound compared with dynamic drivers?

The S12’s 14.8mm planar magnetic element moves air more evenly across the audio band, producing detailed mids and treble with tight, controlled bass without the bloom some dynamic drivers show. Planar drivers often yield lower distortion at similar listening levels, which translates into clearer instrument separation and vocal clarity.

• Large 14.8mm planar diaphragm for uniform response and fine detail retrieval.
• High sensitivity (~102 dB/mW) allows louder playback from smartphones and tablets.
• Balanced tonal presentation: precise mids, crisp highs, and controlled bass.

What makes the S12 comfortable for long listening sessions?

The shell is CNC‑milled with smooth curves and a matte finish to sit naturally in the concha without sharp edges or hotspots. Two side vents reduce internal ear pressure, and multiple ear tip materials and sizes are included so you can tailor the fit and seal for fatigue‑free wear.

• Five‑axis milled aluminum chassis with rounded edges for a secure, smooth fit.
• Side vents reduce in‑ear pressure for comfort during long playback.
• Included foam, standard, and clear tips in S/M/L let you optimize seal and comfort.

How does the stock cable and connector affect real‑world use?

The S12 ships with a detachable 0.78mm dual‑pin cable braided from 128 strands of silver‑plated monocrystalline copper for low impedance and good noise rejection. The cable is available with either a 3.5mm or 4.4mm plug, enabling direct connection to most phones or balanced-capable players without extra adapters.

• Detachable 0.78mm dual‑pin cable for easy replacement and upgrades.
• 128‑strand silver‑plated monocrystalline copper braid for clarity and durability.
• Choose 3.5mm or 4.4mm plug for compatibility with common devices and balanced outputs.

What build details and accessories come with the S12?

The S12’s body is CNC‑milled and finished for a premium look that resists wear while staying lightweight for everyday carry. The package includes multiple tip types and sizes plus documentation and a warranty card so you can start using the earphones straight away.

• 5‑axis milled aluminum chassis with matte finish for durability and refined aesthetics.
• Accessory set: foam, standard, and clear tips (S/M/L), manual, and warranty card.
