## Long description

The Retoo E398 is a 1.5 m audio cable with a 3.5 mm stereo jack on one end and two RCA (Cinch) plugs on the other. It is designed to transmit left and right line-level audio signals between portable devices and home audio equipment. The black cable provides a straightforward wired connection for smartphones, tablets, laptops, portable music players and similar sources to AV receivers, amplifiers, powered speakers or televisions with RCA inputs.
Advantages
This cable offers a simple and reliable analog connection for stereo audio transfer. Its 3.5 mm to dual RCA configuration makes it compatible with a wide range of consumer electronics without the need for adapters. The 1.5 m length gives moderate reach suitable for typical home setups, allowing convenient placement of source devices near listening equipment. The black outer jacket provides a neutral appearance that blends with most home entertainment setups.
Suitable for
Connecting a smartphone, tablet or laptop headphone output to an AV receiver or amplifier
Linking portable music players to powered speakers or stereo systems with RCA inputs
Feeding audio from a TV headphone or auxiliary output into recording devices or external amplifiers
When it may not be suitable
The Retoo E398 is intended for line-level analog stereo signals and is not suitable for digital audio connections, multi-channel surround formats, or speaker-level wiring. It is not designed as a professional studio cable where balanced connections or very low noise and shielding specifications are required. For very long runs beyond 1.5 m, or installations requiring in-wall cabling or higher durability, a different cable type may be preferable.
Key specifications
Cable type: 3.5 mm stereo jack to 2×RCA (Cinch)
Length: 1.5 m
Color: black
Signal: analog stereo, line-level (left and right)
Typical use: consumer audio connections between portable sources and RCA-equipped equipment
How to use
Insert the 3.5 mm stereo plug into the headphone or line output of the source device, ensuring a secure connection. Plug the red and white RCA connectors into the corresponding right and left RCA input sockets on the receiver, amplifier or powered speakers; match colors to maintain correct channel orientation. Set source and receiver volumes to low levels before playback, then adjust levels to the desired listening volume. If the connected device has a selectable output mode, choose the line or headphone output for optimal signal matching.
What to consider before purchase
Ensure your source device has a 3.5 mm stereo output and the target equipment accepts RCA (Cinch) inputs
Verify that a 1.5 m length is sufficient for your intended setup and placement of devices
Consider whether you need a cable with higher shielding or professional-grade connectors for noisy environments
Usage recommendations
Use the Retoo E398 for straightforward, short-range analog stereo connections between portable devices and home audio equipment. Keep cables away from power cords to reduce potential interference and avoid excessive bending or strain at connector ends to preserve longevity.
