LOKUKA USB-C to Dual 3.5mm TRRS Headphone Splitter

LOKUKA's USB‑C to dual 3.5mm TRRS splitter is a compact audio adapter that lets two headphones or TRRS microphones share one USB‑C port with Hi‑Res DAC sound.

Designed for modern phones, tablets, laptops and gaming devices that lack a dedicated audio jack, this Type‑C to 2×3.5mm adapter combines a 24‑bit/96kHz DAC chip and an amplifier to preserve clarity, depth and bass while supporting simultaneous listening or microphone use when both connected cables are TRRS. The rugged metal housing, gold‑plated connectors and crystal nylon braided cable make it travel‑ready and durable for everyday use.

How does this adapter keep audio quality when splitting to two headphones?

The adapter integrates a KT0210 high‑resolution DAC and an amplifier to maintain sonic detail across two outputs. Instead of simply splitting an analog signal, it converts and processes digital audio to deliver clear mids, defined highs and strengthened bass to both connected devices.

• 24‑bit/96kHz DAC ensures accurate digital‑to‑analog conversion.
• Built‑in amplifier improves volume and dynamic response.
• Gold‑plated 3.5mm jacks reduce corrosion and signal loss.
• Works reliably with both headphones and passive speakers.

Will the mic function work for two people at once?

Mic sharing is supported only when both connected headsets or microphones use TRRS plugs (three black rings). If either accessory is TRS or uses separate stereo and mic plugs, the shared microphone or inline controls will not function.

• Requires TRRS plugs on both sides for microphone and inline controls.
• Not compatible with dual‑TRS combos or devices with an existing 3.5mm jack that disables USB‑C audio controls.
• Ideal for simultaneous online classes, calls, or co‑listening when both users have TRRS headsets.

Is the adapter durable enough for daily travel and frequent plugging?

The design focuses on longevity: a matte metal housing for heat dissipation and scratch resistance, a reinforced USB‑C connector rated for 20,000+ swings, and a crystal nylon braided cable that resists tangles and abrasion.

• Metal casing minimizes fingerprints and improves cooling.
• Gold plating on audio jacks for stable long‑term contact.
• Crystal nylon braid prevents fraying and reduces tangling.

What should I check before buying to ensure full functionality?

Confirm your headset and microphone plugs are TRRS if you need microphone sharing. Also note some phones with a separate 3.5mm jack may not support mic or remote controls through the USB‑C port—check your device compatibility to avoid disappointment.

• Ensure both headphones/mics use TRRS (three black rings) for mic support.
• Not compatible with dual‑TRS microphone setups (two‑plug designs).
• Contact LOKUKA support if you’re unsure about a specific phone model’s behavior.

Who is this for: Musicians, students, travelers and families who need to share audio from a modern USB‑C device without sacrificing sound quality will benefit most. It’s also suited to podcasters, streamers and remote workers who want a durable, portable splitter with improved audio fidelity compared with passive splitters. If you require microphone sharing, make sure both accessories are TRRS‑compatible; for pure listening and dual speaker setups the adapter is plug‑and‑play and delivers high‑resolution audio on the go.
