HYTERA EAS03 receive-only acoustic tube earpiece with 2.5 mm jack for BD5, PD4, PD5, PD6, PD78X, X1 series

HYTERA EAS03 is a receive-only acoustic tube earpiece designed for use with HYTERA BD5, PD4, PD5, PD6, PD78X and X1 radio series. The accessory connects to compatible radios via a 2.5 mm jack and delivers discreet audio through a flexible acoustic tube and in-ear bud. It provides a non-transmitting, low-profile option for personnel who need to monitor radio channels without using a microphone or push-to-talk on the earpiece itself.

Advantages

The receive-only design removes transmit functionality, reducing complexity and ensuring the earpiece is lightweight and simple to use. The flexible acoustic tube routes audio to the ear while keeping the microphone area clear, which supports covert or uniformed operations where visible equipment should be minimised. The 2.5 mm jack offers broad compatibility with the listed HYTERA radio series and allows quick connect/disconnect.

Suitable for

• Security staff and guards who only need to monitor communications
• Event personnel and ushers requiring discreet audio reception
• Retail and hospitality staff using HYTERA BD5, PD4, PD5, PD6, PD78X or X1 radios
• Surveillance and covert operations where transmission from the earpiece is not required

When it may not be suitable

This earpiece does not include a microphone or push-to-talk button and therefore is not suitable when the user needs to transmit voice from the earpiece. It is intended solely for audio reception; users who require two-way communication should select a model with integrated microphone and PTT functionality compatible with their radio.

How to use

Insert the 2.5 mm jack into the corresponding audio port on the compatible HYTERA radio. Place the acoustic tube so the earbud sits comfortably in the ear canal and route the tube along clothing to keep it concealed. Adjust radio volume to a comfortable listening level before use. Remove the earpiece by gently pulling the jack from the radio when finished and store the tube and earbud in a clean, dry place to prevent damage.

What to consider before purchase

• Confirm that receive-only functionality meets your communication needs

Usage recommendations

For reliable performance, test the earpiece audio at different volume levels and inspect the acoustic tube and earbud for wear before each shift. Clean the earbud according to hygiene guidelines and replace it if damaged. Avoid exposing the connector and tube to moisture and extreme temperatures to prolong service life.
