Monoprice 35ft 3.5mm to 2-RCA Stereo Audio Cable

This long-run audio cable is built for stable, semi-permanent installs where signal integrity matters. It pairs a 3.5mm stereo male plug with two gold-plated RCA male plugs on a thick, heavy-duty coaxial assembly that reduces noise and preserves clarity across extended distances. Designed with 22AWG conductors and shielding, the cable balances flexibility with robustness so you can route it behind furniture or along baseboards without frequent replacement.

How does this cable keep sound clean over 35 feet?

The Monoprice cable uses shielded 22AWG coaxial conductors to resist electromagnetic and radio-frequency interference that can introduce hums or buzzes. Gold-plated connectors ensure a reliable metal-to-metal contact that resists corrosion over time, maintaining consistent signal transfer even at longer runs.

• 22AWG conductors for lower signal loss than thinner wire
• Individual shielding per conductor to block EMI/RFI
• Gold-plated RCA connectors for corrosion resistance
• Heavy-duty jacket and thicker diameter for durability

Will this cable work with my phone, laptop, or stereo receiver?

Yes — the cable converts a standard 3.5mm stereo output to the left/right RCA pair commonly found on amplifiers, receivers, and powered speakers. It’s ideal for connecting portable sources or computer audio outputs to home audio equipment that lacks a 3.5mm input.

• 3.5mm stereo male to dual RCA male wiring for left/right channels
• Compatible with smartphones, tablets, MP3 players, and PCs that have a headphone jack
• Plugs directly into amplifier or receiver RCA inputs

Is this cable practical for portable use or frequent unplugging?

Because the cable measures 35 feet and uses a relatively thick jacket and connector housings, it’s best suited to more permanent or semi-permanent setups rather than everyday portable use. The weight and size of the connectors make repeated plugging and routing less convenient than lighter, shorter cables intended for mobile use.

• 41mm connector housings are sturdy but not ultra-compact
• 12mm x 6mm cable thickness favors durability over portability
• Recommended for fixed runs behind furniture or AV racks

How should I install and care for this cable for best performance?

Route the cable away from power cords and wireless transmitters to minimize potential interference. Use gentle curves rather than tight bends, secure it with clips or cable ties, and avoid kinking to preserve the shielding and conductor integrity.

• Keep separate from AC power lines to reduce hum
• Avoid sharp bends and repeated flexing at connector ends
• Use cable clips or channels to hide and protect the run

Who is this for? If you need a reliable, long reach connection from a headphone-style output to an amplifier or powered speakers and prefer a durable cable that minimizes interference, the Monoprice 35-foot 3.5mm to dual RCA cable is a practical choice. It suits home audio enthusiasts wiring a living-room system, PC users linking a desktop to hi-fi gear, or anyone installing semi-permanent audio connections where signal quality and build strength matter more than compact portability.
