The UGREEN 3.5mm 4-Pole Audio Extension Cable (40672) adds 0.5m 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.

Gold-plated contacts in threaded metal housings give a consistent connection.

Copper conductors inside a braided nylon jacket for clean sound and long life.

The braid resists tangles and kinks in pockets and bags.

Keep the phone on the bedside table and the earphones comfortably on.
