The UGREEN 3.5mm 4-Pole Audio Extension Cable (40673) adds 1m of reach to your headphones, earphones or AUX connection, so you can move freely from your phone, laptop, TV or car audio. Its 4-pole plug carries stereo sound and the headset microphone, so calls work through it too. Gold-plated contacts and a nylon-braided cable keep the sound clean, and plugging into the extension instead of the device saves wear on your device's jack.

The 4-pole design carries stereo sound and the headset microphone, and works with ordinary 3-pole headphones too.

Enamelled copper conductors and gold-plated contacts carry clear, hi-fi sound.

Metal shells protect the joints and the slim plug fits through phone cases.

Move away from your phone or laptop and keep listening and talking.
