Silver-braided 3.5mm TRRS balanced headphone cable, 150cm

Geekria

Geekria Apollo 3.5mm TRRS Balanced Cable 150cm

SKU CH-1SFM-YRQHM

A 150 cm balanced headphone cable with 3.5 mm TRRS plug, four 24 AWG silver-plated OCC conductors and gold-plated contacts for compatible HIFIMAN, Denon and FiiO models

  • Balanced TRRS 3.5mm pinout (L+, R+, L-, R-) ensures true balanced signal
  • Four-strand 6N OCC and silver-plated copper conductors reduce corrosion and interference
  • Cryogenic annealing on copper and silver-plated copper refines conductor grain structure
  • High-transparency SoftFlex PVC outer jacket adds flexibility and durability
  • 150 cm length and 45 g weight suit portable and desktop use

Balanced TRRS upgrade cable

The Geekria Apollo cable replaces the stock lead on compatible HIFIMAN, Denon and FiiO headphones with a 3.5 mm balanced TRRS connector. Four conductors use cryogenically annealed single-crystal copper and silver-plated copper in a 24 AWG braided structure. The 150 cm length suits desktop listening positions.

Thermals noise and power

Passive copper and silver-plated conductors generate no heat and draw no power, so the cable adds no thermal load or audible noise to the signal chain. Gold-plated contacts resist corrosion for consistent conductivity over time. The transparent SoftFlex PVC jacket remains flexible during extended sessions.

Build fit and clearance

The 3.5 mm TRRS plug fits only sources with a dedicated balanced output; it will not work with standard TRS stereo jacks. The 45 g weight adds minimal strain to headphone sockets. The braided 0.08 mm strand construction keeps the cable supple for easy routing around desktop equipment.

Questions about this item

How do I connect the 3.5mm TRRS balanced plug to my HIFIMAN Edition XS without damaging the pins?

Align the keyed 3.5mm TRRS connector with the headphone socket using the L+, R+, L-, R- pin configuration, then push straight in until the gold-plated plug seats fully; do not twist or force it, as the balanced wiring only works with compatible 3.5mm balanced outputs.

What part of the cable is most likely to wear out first and can it be replaced?

The SoftFlex PVC outer jacket and gold-plated 3.5mm connector endure daily flexing, but the four 24AWG conductors inside are not user-serviceable; if the braid frays or a channel cuts out, the whole 150cm cable must be replaced.

At what point does the 24AWG four-strand construction limit performance during long listening sessions?

The 45g cable handles typical headphone currents without heating, so the practical limit is mechanical — repeated bending at the plug or Y-split can fatigue the 0.08mm strands before any electrical bottleneck appears.
