Audio cable Hosa CMM-103R 1 m, 3.5mm TRS male-to-male, oxygen-free copper, magnetically shielded, black

Hosa CMM-103R is a 1 m 3.5mm TRS male-to-male audio cable designed for balanced or stereo line-level connections between portable devices and audio equipment. The cable uses oxygen-free copper (OFC) conductors and a magnetically shielded construction to minimise interference and maintain clear signal transmission. Its black jacket and right-angle connector configuration make it suitable for tight spaces and typical consumer audio setups, providing a compact and reliable connection between headphone outputs, portable players, laptops, mixers and line inputs that accept a 3.5mm TRS plug.

Advantages

The oxygen-free copper conductors offer improved conductivity and reduced signal degradation compared with standard copper, while the magnetic shielding helps suppress hum and radio-frequency interference for clearer audio. The 1 m length balances flexibility and reach for desktop and portable use, and the right-angle connector reduces strain in confined mounting situations. The cable's build focuses on consistent stereo or balanced line performance and compatibility with a wide range of consumer and pro-audio devices that use a 3.5mm TRS interface.

Suitable for

• Connecting portable media players or smartphones to powered speakers or car audio auxiliary inputs
• Linking laptop headphone outputs to audio interfaces, mixers or recorders with 3.5mm TRS inputs
• Interfacing headphone outputs to small mixers, monitor controllers or portable recorders
• Temporary studio setups where a compact, shielded 1 m interconnect is required

Key specifications

• Connector type: 3.5mm TRS male-to-male
• Cable length: 1 metre
• Conductor material: oxygen-free copper (OFC)
• Shielding: magnetic shielding to reduce EMI/RFI
• Color: black
• Intended signal: stereo or balanced line-level audio

How to use

Insert each 3.5mm TRS male plug firmly into the corresponding headphone or line input/output jacks on your devices. Ensure connectors are fully seated to avoid intermittent contacts. For balanced operation, confirm both connected devices support balanced 3.5mm TRS wiring; otherwise use the cable for standard stereo line-level connections. Avoid sharp bends near the connectors and route the cable away from power transformers or fluorescent lighting to minimise potential interference.

Usage recommendations

For best performance, use the cable at its 1 m length without excessive tension, keep connectors clean, and avoid running the cable parallel to mains power cables. When connecting mobile devices, use a snug-fit on jacks to prevent accidental disconnection; for permanent installations consider strain relief or securing the cable to reduce connector stress.
