The Cablexpert CCA-417M is a practical audio adaptor cable designed to split a single 3.5mm 4-pin TRRS plug into two separate 3.5mm 3-pin TRS sockets. This allows you to connect a standard headset and a separate microphone to devices like tablets, netbooks, or ultrabooks that feature a combined audio and microphone port. Measuring 0.2 meters in length, this black analog cable provides a compact and tidy connection without excess wiring. It is a useful tool for users who want to use their existing standalone audio peripherals with modern hardware that only offers a single integrated jack.
