2-Wire Earbud with Clip Microphone & PTT

The Motorola HMN8435 Earbud with Clip Microphone and Push-to-Talk (PTT) provides a lightweight and discreet audio solution for compatible Motorola portable two-way radios.

Featuring a compact single-ear earbud, the HMN8435 delivers incoming radio communications directly to the user's ear. This provides greater privacy than listening through the radio's external speaker and makes the accessory particularly useful in professional environments where radio traffic should remain discreet.

The HMN8435 uses a 2-wire configuration. One wire connects to the earbud for receiving incoming communications, while the second wire contains the clip-mounted microphone and Push-to-Talk control.

The integrated microphone and PTT assembly can be clipped to the user's clothing, allowing the microphone to be positioned conveniently for outgoing communications. Users can initiate transmissions using the accessory's PTT button without repeatedly reaching for or removing the radio.

Separating the receive earpiece from the microphone/PTT assembly also provides greater flexibility when positioning and routing the accessory cables.

Its compact and lightweight design makes the HMN8435 well suited for extended use and provides a practical alternative to larger headsets and remote speaker microphones.

The HMN8435 is ideal for retail, hospitality, security, education, property management, event operations, maintenance, and other professional environments where users need convenient and discreet two-way radio communications.

Important

The HMN8435 is a 2-wire transmit-and-receive audio accessory.

One wire provides received audio through the earbud, while the second wire contains the clip-mounted microphone and Push-to-Talk control.

The HMN8435 is not a receive-only earpiece. The integrated microphone and PTT allow the user to both receive and transmit radio communications.

This accessory should not be confused with the similar HMN9036, which Motorola lists separately as another 2-wire earbud with clip microphone and PTT.

Always verify compatibility with the specific Motorola radio before ordering.
