H HIFIHEAR Obsidian Black IEM Cable — Graphene + 6N OCC

Built for audiophiles who want a measurable upgrade from stock wires, the Obsidian Black combines a hybrid conductor layout, dense 4-strand 196-core braiding and precision 21AWG construction to reduce interference and improve resolution. Durable aircraft-grade aluminum hardware, multiple connector options and both 3.5mm and 4.4mm plug choices make this cable flexible for portable and balanced setups.

How does this cable change the sound of my IEMs?

The Obsidian Black uses a graphene + 6N OCC hybrid conductor to balance frequency performance: graphene enhances treble extension and transient clarity while 6N OCC adds body and smoothness to mids and lows. The result is improved separation, lower distortion and a more airy presentation without thinning the lower register.

• Graphene conductors for extended, detailed highs and faster transients.
• 6N OCC for warm, full mids and controlled bass response.
• Hybrid wiring reduces smearing and improves instrumental separation.

Will this cable hold up to daily use and travel?

Yes — the Obsidian Black is engineered for real-world durability. Its 21AWG precision braid and 4-strand 196-core construction increase tensile strength, resist tangling, and maintain flexibility for everyday handling.

• Aircraft-grade aluminum plugs, splitter and pins for wear resistance.
• Dense braiding resists knots and protects inner conductors from stress.
• Checkerboard outer pattern for grip and a premium feel in hand.

Which earphones and devices are compatible with this cable?

The Obsidian Black supports a wide range of mainstream IEM standards through optional MMCX, 2-pin and QDC connectors and includes both 3.5mm unbalanced and 4.4mm balanced plug options. Gold-plated contacts improve connectivity and reduce oxidation for reliable long-term performance.

• Selectable MMCX / 2-pin / QDC connectors to match most IEMs on the market.
• 3.5mm and 4.4mm plug variants for unbalanced and balanced sources.
• Gold-plated pins and plug for better contact and reduced wear.

How does the cable’s construction affect noise and interference?

The precise 21AWG cross-braid and high-density 196-core layout create a stable, low-noise signal path that minimizes electromagnetic interference. That cleaner electrical environment helps reveal subtle details and keeps the soundstage more stable at different volume levels.

• Cross-braided 21AWG reduces microphonic noise and EMI pickup.
• High-density cores provide consistent impedance and signal integrity.
• Lightweight yet rugged design preserves both portability and performance.

Who is this for: The H HIFIHEAR KBEAR Obsidian Black cable is aimed at listeners who want a tangible sonic upgrade from stock cables — especially those using high-resolution IEMs, portable balanced players, or DAC/amp setups. It’s suitable for audiophiles seeking improved treble clarity and midrange presence, musicians and sound engineers needing accurate monitoring, and everyday users who value durability and versatile connectivity in a premium replacement cable.
