Cavo adattatore audio Vention 2×3,5 mm maschio a jack 3,5 mm a 4 poli femmina, 0,3 m, nero

The Vention 2 in 1 3.5mm Audio Cable converts a single 4-pole (TRRS) 3.5mm female jack into two 3.5mm male plugs for separate earphone and microphone connections. This 0.3 m black cable is made with cotton-braided insulation, enameled copper conductors, gold-plated connectors and an aluminum alloy shell with an adjustable ring for length control. It lets you connect headsets that use separate mic and headphone jacks to devices with a combined TRRS socket, improving private listening and enabling headset microphone use when the headset supports microphone signal transmission.

Advantages

The cable provides stable signal transmission through enameled copper conductors and corrosion-resistant gold-plated connectors, while the cotton-braided exterior increases flexibility and hand comfort. The aluminum alloy frosted shell reduces interference and the movable ring allows slight adjustment of the exposed cable length. At 0.3 m it is compact for desktop or laptop setups and supports using Hi‑Fi earphones in place of built-in laptop speakers.

Suitable for

• Connecting a headset with separate headphone and microphone plugs to a laptop or phone with a 3.5 mm TRRS jack
• Using earphones with microphone support for gaming, online meetings and internet calls
• Replacing laptop speakers with earphones for private listening

Key specifications

• Connector 1: 2 × 3.5 mm male (headphone + microphone)
• Connector 2: 3.5 mm female 4‑pole (TRRS)
• Colour: Black

How to use

Insert the 3.5 mm TRRS female end into the device with the combined headset jack. Plug the two 3.5 mm male connectors into the corresponding headphone and microphone ports of your headset. Ensure the headset supports microphone signal transmission; if the headset lacks a microphone function or uses a different pin standard (for example some Apple/Beats or CTIA variants), the microphone may not work. Adjust the movable ring to set the desired exposed cable length.

Recommendations

Use caution if your headset is an Apple, Beats or CTIA-specific model — pin definitions may differ and cause microphone incompatibility. Only earphones/headsets that support voice/microphone transmission will pass audio to the microphone line.
