Hetai Tech 3.5mm TRRS Y Splitter Male to 2 Female 20cm

3.5 mm TRRS Y Splitter

This adapter separates a single 3.5 mm combo audio port into distinct headphone and microphone jacks. It enables older headsets with separate plugs to work with newer laptops, tablets or phones that only provide a combined socket. The gold-plated connectors and TPE jacket aim to preserve signal quality in daily use. It is a compact accessory for anyone needing dual audio connections from one port.

Build integration and portability

The 20 cm cable plugs directly into the device's 3.5 mm TRRS jack and presents two female sockets for standard 3.5 mm plugs. No external power or software drivers are required, so it fits into any setup without consuming USB ports or adding bulk. Its short length keeps cable clutter low on a desk or inside a laptop bag. It works with any portable device that uses a four-position 3.5 mm jack.

Capacity and headroom

The splitter handles stereo headphone output and mono microphone input simultaneously through the two female ports. It resolves the issue where certain condenser microphones fail to become the default input on Apple devices, allowing automatic switching. The adapter does not amplify signals or convert digital audio; it only routes the existing analogue connections. Users needing longer reach or additional ports will need a different solution.
