Discreet Acoustic Tube Listening Accessory
Low-Profile Surveillance Style Audio for Professional Handheld Transceivers
The Icom SP26 is a genuine factory acoustic tube earphone engineered to provide private, discreet voice reception for team members in high-security, retail, hospitality, and corporate environments. Outfitted with a standard single-pin 2.5mm plug, this professional surveillance earpiece interfaces cleanly with compatible tie-clip microphones and specialized speaker mic assemblies. Shifting audio outputs away from public speaker housings directly into the operator's ear allows teams to manage confidential dispatches without alerting nearby crowds or guests.
Designed to deliver exceptional vocal clarity while remaining virtually invisible to the public, the assembly relies on a clear, medical-grade acoustic sound tube. This flexible tube structure easily routes behind the earlobe, providing complete freedom of physical head movement without pulling or creating skin irritation during extended work shifts. The lightweight acoustic delivery system minimizes ear fatigue, ensuring communication channels remain active, crisp, and comfortable from the initial briefing to the end of the day.
The earphone operates at an optimal thirty-two-ohm electrical resistance profile to ensure efficient audio processing while minimizing energy draw from the host radio battery pack. A resilient plastic clothing clip comes integrated along the black lead wire, enabling users to secure slack cabling flat against their clothing or uniform collars. This structural precaution eliminates snag hazards from loose lines, maintaining total operational safety in fast-moving commercial and public safety operations.

Frequently Asked Questions
How does this acoustic tube earphone attach to my two-way radio?
This accessory doesn't plug directly into the large side ports of most multi-pin radios. Instead, it is built to attach right into the dedicated 2.5mm audio adapter port located on the side or bottom of your tie-clip microphone or lapel microphone housing.
Can the clear acoustic sound tube be replaced if it wears out?
Yes, the clear plastic acoustic tube mechanism uses a convenient twist-lock quick disconnect barb base. If the plastic yellow-tints over years of field use or becomes clogged with dirt, you can twist the pipe off and replace just the tube assembly.
Is the rubber ear bud insert reversible for either the left or right ear?
Yes, the earphone structure is completely symmetrical and universal. You can route the acoustic pipe over the top structure of either your left or right earlobe and rotate the soft rubber tip to sit comfortably on either side of your face.
Does this earphone include an inline push-to-talk microphone button?
No, this specific part number is a listen-only earpiece accessory. To transmit voice dispatches back to your team, you will speak directly into the microphone capsule element on your companion lapel microphone or tie-clip unit.
Can I wash the flexible plastic parts of the surveillance loop?
Yes, you can disconnect the clear acoustic sound pipe from the black wire adapter base and flush it clean with warm water and mild soap. Ensure the internal air chamber is completely dry and free of water drops before snapping it back onto the base.
