SA-iEFRM25 - 25' Headphone Extender Cable 1/4" TRS Male to 1/8" Female
The SA-iEFRM25 headphone extension cable bridges the gap between consumer headphones and professional audio equipment. This 25-foot cable connects standard 1/8" (3.5mm) headphones to mixers, audio interfaces, and amplifiers with 1/4" TRS outputs.
Built with 20-gauge wire, this extension cable maintains signal integrity across its full 25-foot length. The TRS configuration ensures proper stereo signal transmission while minimizing noise and interference that can plague inferior cables.
The cable features a 1/4" TRS male connector on one end and a 1/8" female jack on the other. This design lets you use consumer headphones with studio monitors, mixing consoles, and professional recording equipment. The 20-gauge conductors provide reliable signal transfer without degradation, while the durable construction handles regular studio and live sound use.
Recording engineers use this cable to extend headphone reach in control rooms and live rooms. DJs rely on it to connect personal headphones to booth monitors and mixers positioned away from the performance area. Home studio producers appreciate the freedom to move around while tracking without being tethered to their audio interface.
The cable connects any device with 1/8" headphone output to equipment with 1/4" headphone jacks. No adapters needed—just plug in and monitor. Each cable includes Seismic Audio's one-year warranty and ships ready for immediate use in professional and home studio environments.
