What this adapter does

The Defendwe splitter turns a single 3.5mm combo headset jack into separate 3.5mm headphone and microphone ports. It lets you connect legacy headsets that use distinct plugs to modern laptops, tablets or phones that only provide one four-position socket. The 20cm cable adds minimal bulk and fits easily in a laptop bag.

The connector layout that matters

Connector A is a 3.5mm male plug that inserts into the combined audio port. Connector B provides two 3.5mm female sockets, one labelled for headphones and one for a microphone. Gold-plated contacts and a TPE jacket are used for the connections. No other interface or connector type is present on this adapter.

Behaviour with continuous use

The short 20cm length keeps signal paths short during extended calls or recording sessions. The TPE cable resists tangling when the adapter stays plugged in for long periods. Passive wiring means there is no active circuitry to overheat or draw power from the host device.

Questions about this item

What does the 20cm length mean when the splitter is plugged into a laptop?

The 20cm cable lets the two 3.5mm female ports sit on your desk while the male plug stays in the combo jack, so headphone and microphone cables reach comfortably without pulling on the socket.

How does the 3.5mm 4‑position connector limit what headsets can be used?

The single male plug carries both stereo output and microphone input on a 4‑pole 3.5mm jack, so it only works with headsets that use the same combined connector — separate headphone and mic plugs need this splitter to connect.

What clearance does the gold‑plated male plug and TPE cable need behind the audio port?

The straight 3.5mm male plug plus the 20cm flexible TPE tail require a few centimetres of free space behind the combo jack so the splitter can hang without bending the connector or stressing the port.
