UGREEN 3.5mm Jack to 3.5mm Jack Cable 1.5m — UGR550BLK, black

UGREEN 3.5mm Jack to 3.5mm Jack Cable 1.5m (black) is a straightforward analog stereo audio cable designed for wired audio transmission between devices with 3.5mm TRS ports. With 1.5 meters of length and male 3.5mm connectors on both ends, the cable supports line-out to line-in connections such as smartphone to car stereo, laptop to powered speakers, or portable music player to headphones with an auxiliary input. The cable offers a simple, no-configuration solution for transferring stereo audio signals.

Advantages

The UGREEN 3.5mm cable provides universal compatibility with most devices that use a standard 3.5mm stereo jack. Its 1.5 m length allows flexible placement of connected devices without excessive slack. Gold-plated connectors ensure reliable contact and corrosion resistance for consistent audio transmission. The cable's construction is intended to reduce signal interference and preserve stereo separation for clear playback of music and voice content.

Suitable for

• Connecting smartphones, tablets or laptops to car stereos with AUX input
• Linking portable audio players to powered speakers or home stereo systems
• Using as an auxiliary cable for headphones, external sound cards, or mixing consoles with 3.5mm inputs
• Temporary or permanent wired audio connections in offices, classrooms, or travel setups

When it may not be suitable

This cable carries analog stereo signals and does not support digital audio formats, microphone-specific TRRS wiring, or inline remote functions. It may not be suitable where a balanced connection, optical/digital audio, or specialized microphone wiring is required. For devices that use USB-C, Lightning, or wireless connections exclusively, a different adapter or cable will be needed.

Key specifications

• Connector type: 3.5mm TRS male to 3.5mm TRS male (stereo)
• Cable length: 1.5 m
• Conductor: stranded copper (standard audio grade)
• Connector plating: gold-plated contacts for corrosion resistance
• Cable color: black

How to use

Insert one 3.5mm male connector into the headphone or line-out socket of the source device and insert the other end into the AUX or line-in socket of the receiving device. Ensure both devices are powered and volume levels are set to an appropriate level before playback. For best results, route the cable away from power adapters and large electrical appliances to minimise potential interference. Disconnect by gently pulling the connector, not the cable, to avoid damaging the termination.

What to consider before purchase

• Verify both devices have standard 3.5mm stereo (TRS) female sockets
• Confirm whether microphone or remote control functionality is required (this cable is TRS stereo only)
• Check if a longer or shorter cable length would better suit your setup
• Consider device compatibility if your equipment uses USB-C, Lightning, or digital/optical audio

Usage recommendations

For reliable audio quality, keep the cable untangled and avoid tight bends near the connectors. If using in a vehicle, route the cable so it does not interfere with controls or pedals. For stationary setups, secure the cable with clips or cable ties to reduce strain on connector ends.
