The Cablexpert CCA-417W is a compact audio splitter designed to separate a combined headset signal into two distinct channels. It features a 3.5mm 4-pin male connector that plugs into a single TRRS port, splitting the audio into two 3.5mm 3-pin female sockets. To help you easily identify the connections, the female ends are color-coded with one green and one red port. Measuring just 0.2 meters in length, this white analog adaptor is small enough to keep your workspace tidy without excess cabling. It is a practical choice for users who want to connect a standalone microphone and a pair of headphones to a device that only has a single combined audio jack.
