Linsoul Terras 4N Single-Crystal Copper IEM Cable 1.25m

The Linsoul Kiwi Ears Terras is a high-purity 4N single-crystal copper upgrade cable for IEMs, offering flexible Litz construction, interchangeable 3.5mm and 4.4mm plugs, and a durable 400D bulletproof fiber sheath.

If you want clearer detail, improved noise rejection, and a comfortable cable that fits both portable and desktop rigs, the Terras delivers a neutral, natural presentation without changing your earphones’ tuning. Built from 4N single-crystal (OCC) copper in a 4-core, 32AWG Litz-style braid, this 1.25m cable prioritizes conductivity and flexibility while protecting the conductors with a rugged outer layer. The plug system supports single-ended 3.5mm and balanced 4.4mm terminations, so it adapts to a wide range of sources and personal listening setups.

How does the 4N single-crystal copper affect sound quality?

The Terras uses oxygen-free, single-crystal copper to lower resistance and refine signal transfer, which helps reveal more micro-detail and preserves timbral accuracy. It aims to present a clean, balanced sound rather than adding coloration.

• 4N OCC copper improves conductivity for clearer highs and tighter lows.
• Single-crystal construction reduces grain and distortion in complex passages.
• Maintains natural instrument timbre and vocals without artificial warmth.

Will the Litz-type 32AWG design reduce cable noise and microphonics?

Yes — the Litz-style braid with multiple thin strands lowers electromagnetic interference and reduces cable microphonics, making the Terras quieter on the ear during movement. The design balances flexibility with signal integrity for everyday use.

• 32AWG strands braided to decrease inductance and skin-effect losses.
• Reduced handling noise when wearing or adjusting IEMs in daily use.
• Better noise rejection around portable gear and crowded RF environments.

What devices and connectors are compatible with this cable?

The Terras ships with interchangeable terminations for 3.5mm single-ended and 4.4mm balanced outputs, covering the majority of smartphones, DAPs, desktop amps, and headphone amps. Its universal 2-pin or MMCX-style connectors (depending on your IEM) make swaps straightforward for many popular monitor models.

• Interchangeable 3.5mm and 4.4mm plugs for portable and balanced systems.
• Works with most universal and custom-fit IEMs that accept detachable cables.
• 1.25m length suitable for pocketed players and amp-tethered listening.

How durable and comfortable is the cable for daily use?

The Terras combines a 400D bulletproof fiber outer sheath with spring-resistant inner wires to resist fraying and kinking while staying supple. The result is a cable designed to survive commuting, stage use, and long listening sessions without becoming stiff or fragile.

• 400D bulletproof fiber sheath protects against abrasion and wear.
• Flexible Litz braid prevents memory and tangling during storage.
• Lightweight 1.25m length reduces strain on connectors and ears.

Who is this cable for? The Linsoul Kiwi Ears Terras is aimed at audiophiles and serious music listeners who want a neutral, high-resolution upgrade for detachable IEMs. It suits users who switch between portable players and balanced rigs, performers needing reliable stage cabling, and anyone looking to improve clarity without altering their earphones’ voicing. If you value material purity, low handling noise, and a rugged yet flexible cable build, the Terras is engineered to meet those needs while staying broadly compatible with modern audio sources.
