EarHugger 2.5mm Listen-Only Acoustic Tube Earpiece for Two-Way Radio Speaker Mic Jacks. Receive-only Headset with Earbud, Open Ear Inserts, Extra Tubes, and Frame. Black Long EH-EPT-1003

100% compatible with all OEM speaker mics ^^ Includes a complete accessory kit with 2 extra eartubes (one clear, one black), 2 EarHugger over ear frames, and medium open-ear inserts (OPE) ^^ Premium Speaker, Gold Plated Connector, High Quality Acoustic Tube, Reinforced earphone clip ^^ Check your radio or speaker mic headphone jack type before ordering to ensure correct plug. 2.5 mm is smaller than standard headphone plug - common on Harris, Otto, and some other speaker mics. But if a standard headphone plug fits in your earpiece jack, you probably need a larger plug (also available - select 3.5 mm long style) ^^

If the OPEs do not fit, contact us at earhugger. com and we will help you find the right size and send them to you at no cost ^^ Ruggedized design - not just words. Field-repairable / replaceable everything - cable, speaker, tubes, inserts. One-year, no-hassle Warranty
