Professional and Consumer Audio Cables for Every Connection

Connect headphones, speakers, microphones, and audio equipment with our selection of audio cables, part of our cables catalog. We carry 3.5mm, XLR, RCA, and optical audio cables for both professional and consumer applications.

Common Audio Cable Applications

• Headphone and speaker connections — 3.5mm aux cables for connecting headphones, portable speakers, and audio sources
• Professional microphone hookups — XLR cables for studio microphones, PA systems, and live sound equipment
• Stereo audio distribution — RCA cables for connecting amplifiers, receivers, and powered speakers
• Digital audio connections — optical (TOSLINK) cables for soundbars, A/V receivers, and digital audio sources
• Conference room audio — cables for connecting speakerphones, ceiling microphones, and room audio systems

Audio Cable Types

• 3.5mm (aux/headphone) — the universal mini-jack for headphones, portable speakers, and line-level audio. Available in straight and right-angle connectors.
• XLR — the professional standard for microphones and balanced audio. Three-pin design rejects noise over long cable runs in stage, studio, and broadcast environments.
• RCA audio — red and white stereo pair for connecting consumer audio equipment like receivers, turntables, and powered speakers.
• Optical (TOSLINK) — fiber optic digital audio for soundbars, gaming consoles, and A/V receivers. Immune to electrical interference.
• 1/4-inch (6.35mm) — standard connector for guitars, keyboards, studio monitors, and professional audio interfaces.

Choosing the Right Audio Cable

For consumer audio like headphones and Bluetooth speakers, 3.5mm cables are universal and inexpensive. For professional audio in studios, stages, and broadcast, XLR cables are the standard because their balanced design cancels out noise over long runs. For home theater and soundbar connections, optical cables provide clean digital audio without ground loop hum.
