Professional headphone extension cables designed for recording studios, DJ booths, and live sound engineers who need reliable 25-foot reach without signal degradation. This 4-pack of SA-iEFRM25 cables connects standard 1/8" (3.5mm) headphones to professional mixing consoles and audio interfaces with 1/4" TRS outputs.

Each cable extends your headphone connection by 25 feet while maintaining full stereo signal integrity through heavy-duty 20-gauge wire construction. The TRS 1/4" male connector fits standard professional audio equipment, while the 1/8" female jack accepts any consumer or pro headphone with a standard mini plug.

The 20-gauge wire gauge provides low resistance signal transmission that preserves frequency response across the entire audio spectrum. At 25 feet, these cables give sound engineers the mobility to move around control rooms, stages, or recording spaces without losing connection. The robust construction handles repeated plugging, unplugging, and cable runs typical in professional environments.

Recording engineers use these for tracking sessions where musicians need headphone monitoring away from the control room. DJ setups benefit when the mixing position is separated from booth monitors. Live sound applications include connecting headphones to monitor consoles positioned away from the mixing board.

Each cable terminates in gold-plated connectors that resist corrosion and ensure reliable signal contact. The pack includes four identical 25-foot cables, providing backup connections or multiple monitoring positions from a single source.

Seismic Audio backs these headphone extenders with a one-year warranty against manufacturing defects.

Frequently Asked Questions

What type of headphones work with these extension cables?

These cables work with any headphones that have a standard 1/8" (3.5mm) plug, including most consumer headphones, studio monitoring headphones, and professional DJ headphones. The female 1/8" connector accepts both stereo and mono plugs, making them compatible with virtually all standard headphone models.

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

Yes, the 1/4" TRS male connector plugs directly into headphone outputs on mixing consoles, audio interfaces, and professional recording equipment. This connection provides full stereo signal from professional gear to your headphones without requiring additional adapters.

Will 25 feet of cable cause signal loss or audio quality problems?

The 20-gauge wire construction minimizes signal degradation over the 25-foot length, maintaining frequency response suitable for professional monitoring applications. While some minimal high-frequency rolloff occurs with any extension, these cables preserve signal integrity for critical listening in recording and live sound environments.

How many people can monitor simultaneously with this 4-pack?

This 4-pack allows four separate headphone monitoring positions from four different sources, or you can daisy-chain multiple cables for longer runs. Each cable requires its own headphone output, so you'll need a mixing console or distribution system with multiple headphone sends for simultaneous multi-person monitoring.

Do these work for extending instrument cables or just headphones?

These are specifically designed for headphone extension and stereo audio signals. While the connectors are compatible with instrument cables, the impedance and signal characteristics are optimized for headphone loads rather than instrument pickups or line-level signals.
