The OTG Cable Matters More Than You Think: KEYSION Dual Type-C, Compared
In the combination of phone + dongle DAC, the OTG cable is often the most compromised part—many people use the generic cable included in the bundle, which has unstable power supply, loose connections, and the DAC occasionally drops out. YCX makes this "digital bridge" to HiFi cable standards: 8 strands of 49-core silver-plated oxygen-free copper wire, aluminum alloy shell, and gold-plated contacts.
| Parameter | YCX Value | What This Means |
|---|---|---|
| Interface | Type C → Type C | Direct connection to mainstream phones, tablets, and dongles |
| Cable Core | 8 strands × (49/0.05mm) silver-plated oxygen-free copper | 392 fine copper wires, ample margin for power and signal |
| Shell | Aluminum alloy | Balance of shielding and durability |
| Contacts | Gold-plated | Anti-oxidation, reduced contact resistance |
| Length | 1m | Reasonable length for pocket-sized DAPs + dongles |
Some say digital cables "transmit 0s and 1s with no sound quality difference" — that's true for the signal itself, but this cable sells on no dropouts, no loose connections, no oxidation. Staying trouble-free after a year of use is its greatest value.
- For: phone/tablet + dongle users; people who experience frequent disconnections with the bundled OTG cable; those who want to equip a decoder like the 02 Pro / 01 with a cable that does it justice.
- Not for: iPhone Lightning models (requires a Lightning OTG adapter solution); those who need 3.5mm analog output (that's the job of the S1/ S2).
FAQ
Does an OTG cable really affect sound quality?
The "sound quality difference" in digital transmission mainly lies in stability: disconnections and pops caused by poor contact and power fluctuations. When the signal is intact, the cable itself does not alter the sound content.
What settings are needed on Android phones?
Most Android devices work plug-and-play; some systems require enabling "USB audio routing" in developer options. For best results, use a player app with USB exclusive output.
Can it power the DAC at the same time?
During OTG connection, it is standard behavior for the phone to power the DAC. YCX's cable specifications provide sufficient power margin; however, the DAC's power consumption will accelerate the phone's battery drain. For extended use, it is recommended to have a power bank ready.
Is the 1m length sufficient?
It is sufficient for pocket and desktop handheld scenarios. If you need longer cable routing on a desktop, it is recommended to choose a powered desktop solution rather than extending the OTG cable (long OTG cables are prone to insufficient power supply).
