Fostex ET-TH2.0UB2Y is the standard-issue unbalanced Y-cable supplied with the TH910 and TH919, also compatible with the TH1000RPmk2 and TH1100RPmk2. It runs from a single 6.3 mm TRS connector at the source end to two separate 3.5 mm TS plugs at the headphone end — one per earcup. The conductor is high-purity OFC wrapped in a flexible PVC jacket, and all connectors are gold-plated. At 2.0 m, it suits desktop amplifier and near-field listening setups.
Dual 3.5mm TS earcup connections — the engineering rationale
The Y-topology with two independent 3.5 mm TS plugs at the headphone end replaces the rhodium-plated 2-pin system used on earlier TH-series models like the TH900mk2 and TH909. Each earcup gets a dedicated, mechanically independent connection with no shared ground at the split point — this eliminates a potential channel crosstalk source at the connector level. Detachment and reattachment require no tools: both 3.5 mm TS plugs pull directly from the earcup sockets. High-purity OFC in PVC retains flexibility at low temperatures and delivers consistent electrical parameters from first use — there is no break-in period or burn-in behaviour to account for.When replacing the stock cable with ET-TH2.0UB2Y makes sense
The TH910 and TH919 operate at 25 Ω impedance; the TH1000RPmk2 and TH1100RPmk2 at 32 Ω. The ET-TH2.0UB2Y is engineered to match these loads without impedance mismatch or shielding inconsistencies that can accompany budget aftermarket alternatives. If the factory cable sustains mechanical damage at the connector or jacket, this OEM replacement restores the original signal path specification without any acoustic variables introduced by third-party cable construction.KEY FEATURES
