Why Professionals Choose the Hytera Earpiece EAS03
The EAS03 is a discreet earpiece designed for covert use. It consists of a clear acoustic tube that sits in the ear. The earpiece connects to the radio through a remote speaker microphone because it is receive-only. The remote speaker microphone handles the PTT and microphone functions, so the earpiece itself has no microphone or buttons. The EAS03 connects to a remote speaker microphone, such as the Hytera SM26M1, through a 2.5 mm audio jack.
The Hytera EAS03 has a rated power of 10 mW and a maximum power of 30 mW, with an output level of 117 ± 3 dB at 1 kHz. This provides clear audio even in noisy environments. The coiled cord extends up to 36 inches, providing enough length to run it from a lapel-mounted microphone to the ear. Weighing just 0.7 oz, the earpiece is comfortable to wear for extended periods.
The EAS03 acoustic tube is detachable for easy cleaning or replacement, and the connecting cable has a quick-disconnect feature for switching between radios. Using the genuine Hytera EAS03 covert earpiece provides discreet communications and clear audio.

FAQ
Can the EAS03 be connected directly to a two-way radio?
No. The EAS03 is receive-only and plugs into a remote speaker microphone's 2.5 mm jack, such as the SM26M1. The speaker mic connects to the radio and carries the PTT and microphone. Order the earpiece and a compatible speaker mic together for a complete setup.
Will the EAS03 2.5 mm plug work with other brands' speaker mics?
The 2.5 mm plug is set to mate with Hytera remote speaker mics like the SM26M1. A 2.5 mm jack is common, but the audio level and wiring are built for Hytera. Do not assume the EAS03 fits a Motorola or Kenwood speaker mic, even where the jack looks the same.
Is the EAS03 an original Hytera part or an aftermarket copy?
It is the original Hytera EAS03, supplied by AXDIGITAL as an authorized Hytera dealer. The speaker output and 22 Ω load match Hytera's datasheet. An aftermarket tube or driver can change volume and clarity, which matters when audio has to stay quiet and intelligible.
