Professional headphone extension cables for studio monitoring, live sound engineers, and anyone who needs to extend their headphone reach without losing audio quality. The SA-iEFRM25 2-pack delivers 25 feet of reliable extension per cable, connecting your 1/8" (3.5mm) headphones to 1/4" TRS outputs on mixing consoles, audio interfaces, and pro audio equipment.

These cables bridge the gap between consumer headphone connectors and professional audio gear. The 1/4" TRS male connector plugs into your mixer or interface, while the 1/8" female jack accepts any standard headphones, earbuds, or in-ear monitors.

Built with 20-gauge wire for consistent signal transfer, each cable maintains audio integrity across the full 25-foot length. The TRS connection supports stereo audio and is compatible with balanced and unbalanced outputs. Professional-grade connectors ensure secure connections that won't work loose during sessions or performances.

Studio engineers use these for monitoring from control rooms to live rooms. Live sound operators extend their headphone reach to front-of-house positions or monitor splits. Home studio producers connect consumer headphones to professional interfaces and mixers. The 25-foot length covers most studio layouts and small venue requirements.

Each cable features 1/4" TRS male to 1/8" female configuration. No additional adapters needed - just plug your headphones into the female end and connect the male end to your audio source. This 2-pack provides backup cables or simultaneous monitoring setups.

Covered by Seismic Audio's one-year warranty with fast shipping. Professional connectivity that doesn't break the budget, built for daily use in demanding audio environments.

Frequently Asked Questions

What headphones work with these extension cables?

Any headphones or earbuds with a standard 1/8" (3.5mm) plug will work with these cables. This includes most consumer headphones, studio monitors like Audio-Technica ATH-M50x, and professional in-ear monitors. The female connector accepts both TRS (stereo) and TS (mono) plugs.

Can I connect these to my audio interface or mixing console?

Yes, these cables are designed specifically for that purpose. The 1/4" TRS male end plugs directly into headphone outputs on audio interfaces, mixing consoles, monitor controllers, and other pro audio equipment. No adapters needed.

Is 25 feet long enough for studio and live sound work?

25 feet covers most studio control room to live room distances and allows live sound engineers to move around small to medium venues while staying connected. For larger venues or longer runs, you can daisy-chain multiple cables, though signal loss may occur beyond 50 feet total length.

Do these cables work with balanced headphone outputs?

These cables will physically connect to balanced 1/4" outputs, but they carry the signal as unbalanced stereo. Most headphone outputs are unbalanced anyway, so this won't affect performance with typical studio monitors and consumer headphones.

Why would I need two cables instead of just buying one?

The 2-pack provides a backup cable for critical sessions, allows two people to monitor simultaneously from the same source, or lets you set up permanent installations in multiple locations. Having a spare on hand prevents session delays when cables fail.
