Hosa CMM-103 3.5mm TRS to 3.5mm TRS Stereo Interconnect Cable — 3 Feet

Hosa CMM-103: The Short 3.5mm Aux Cable for Desktop Recording and Mixing Rigs

The Hosa CMM-103 is a 3-foot stereo interconnect cable terminated with 3.5mm (1/8") TRS male plugs on both ends — the cable you reach for when two devices share the same 1/8" stereo jack format and you need to bridge them without a coiled mess of slack. Oxygen-free copper conductors and an OFC spiral shield handle the signal, nickel-plated plugs handle the wear, and the 3-foot run is sized for desktop work, podcast tables, mobile rigs, and any setup where a longer cable would just create cable management problems.

What the 3.5mm TRS to 3.5mm TRS Format Actually Solves

This is an unbalanced stereo cable — not a microphone cable, not a balanced TRS, not a Y-cable. It carries left and right channels between two stereo-output or stereo-input devices that both use the 1/8" jack: phone or laptop headphone output to a mixer aux input, computer audio out to a portable speaker, recorder line out to a headphone amplifier, media player to a powered monitor system. If both devices have the same stereo 3.5mm jack, this is the cable that connects them.

3-Foot Length, OFC Construction, and Why Hosa Specs Matter

The 3-foot length matters: too long and the cable coils on the desk, too short and you can't route around a screen. Three feet is the sweet spot for most desktop runs and small mobile rigs. The oxygen-free copper conductors deliver cleaner signal transfer than standard copper, and the spiral OFC shield rejects EMI and RFI bleed from computer monitors, USB hubs, and wireless gear nearby. Nickel-plated plugs resist corrosion over hundreds of plug-and-unplug cycles — the kind of wear a road kit, a remote recording rig, or a daily podcast setup actually puts on a cable.

Where the CMM-103 Belongs in Your Recording Workflow

Use the CMM-103 anywhere two 3.5mm stereo jacks need a short bridge: laptop headphone output to a mixer aux return for music playback during a podcast, recorder headphone monitor send to a backup recorder for safety, phone audio into a livestream mixer for caller interviews, or as a short patch cable in a portable rig. The 3-foot length keeps the workspace clean while delivering the same OFC build quality Hosa uses across its full cable line.
