Stereo 3.5mm Adapter ShiverPeaks 57114-M — stereo audio connectivity

The ShiverPeaks Stereo 3.5mm Adapter 57114-M is a compact stereo audio coupling designed to join two 3.5mm TRS male-terminated cables or extend existing headphone and line-level connections. Built with a metal housing, it provides a simple mechanical and electrical connection for portable audio devices, headphones, speakers and other consumer audio equipment that use standard 3.5mm stereo jacks.

Advantages

This adapter offers a compact, durable metal construction that resists wear from repeated insertion and movement. It enables straightforward stereo signal continuity without active electronics, supporting line-level and headphone-level signals with minimal added bulk. The gender-coupling format makes it convenient for temporarily joining cables or replacing a short broken cable segment when a full replacement is not available.

Suitable for

• Connecting two 3.5mm stereo cables to extend reach
• Linking portable players, smartphones or tablets to external speakers or amplification
• Repairing or bypassing a damaged cable end for temporary use
• Connecting headphones with detachable 3.5mm plugs

Key specifications

• Connector type: 3.5mm TRS stereo female coupling
• Contact configuration: stereo (left, right, common ground)
• Housing material: metal
• Intended signals: headphone-level and line-level audio
• Form factor: compact inline coupler for two 3.5mm plugs

How to use

Insert each 3.5mm male plug into the adapter’s female ends until they click or seat firmly. Ensure plugs are fully inserted to maintain reliable stereo contact and avoid intermittent audio. For best results, connect source and playback devices while both are powered down or volume is low to prevent sudden loud output when establishing the connection. The adapter requires no power or drivers and functions immediately after physical connection.

Usage recommendations

Use the adapter for short-term extensions and temporary repairs rather than long-term routing through high-traffic areas. Avoid excessive bending or pulling at the joined junction to reduce stress on cable terminations. If a permanent, high-quality extension is required, consider a single continuous cable with the required length and shielding.
