RUYAGE HB380 Amplified Speaker Microphone for 4G LTE PoC Radios

RUYAGE HB380 Amplified Speaker Microphone for 4G LTE PoC Radios

The RUYAGE HB380 Amplified Speaker Microphone is a wired external PTT microphone designed for selected 4G LTE PoC radios and network walkie talkies with a compatible K-type 2-pin accessory connector.

Featuring a built-in audio amplifier, 8-ohm 1-watt speaker, external microphone, large Push-to-Talk button, rear clothing clip, 1000mAh rechargeable battery, and USB-C charging, the HB380 makes incoming radio messages easier to hear while providing convenient shoulder-mounted PTT operation.

It is suitable for transportation, construction, security, logistics, warehouses, outdoor operations, events, and other working environments where the radio's built-in speaker may be difficult to hear.

Key Features

Amplified Speaker Output

The HB380 includes a built-in amplifier chip and an 8Ω / 1W speaker designed to provide stronger incoming audio than a small radio speaker.

• Amplified incoming voice playback
• 1-watt external speaker output
• Helps improve audibility around vehicles, crowds and machinery
• Suitable for professional and outdoor communication

Perceived volume and clarity depend on the connected radio, audio settings, network quality, message quality, battery level, and surrounding noise. No specific decibel output has been provided, so this product should not be described as hearing protection or guaranteed audible in every environment.

External Push-to-Talk Microphone

The side-mounted PTT button allows users to transmit without repeatedly removing the radio from a belt, pocket, or equipment mount.

• Press and hold the PTT button while speaking
• Release the button to receive incoming communication
• Built-in microphone for outgoing voice transmission
• Radio-style operation for fast team coordination

For clearer transmission, position the speaker microphone near the upper chest or shoulder and speak toward the microphone opening.

Designed for Selected 4G LTE PoC Radios

The HB380 is designed for compatible Push-to-Talk over Cellular radios, 4G LTE network walkie talkies, and PoC communication devices that support an external K-type speaker microphone.

The microphone does not provide its own LTE service, SIM card, PoC platform, or internet connection. All communication functions are supplied by the connected radio.

K-Type 2-Pin Radio Connection

The coiled cable terminates in a K-type two-pin plug, also commonly described as a K plug or Kenwood-style 2-pin connector.

• Direct wired connection
• No Bluetooth pairing required
• Audio, microphone and PTT control through the connected radio
• Approximately 1.2-meter cable length

A similar-looking K-type connector does not always guarantee compatibility. Connector wiring, pin spacing, radio firmware, audio levels and PTT recognition may differ between models.

1000mAh Rechargeable Amplifier Battery

The built-in 1000mAh lithium-ion battery supplies power to the amplified speaker system.

• Rechargeable amplifier battery
• USB Type-C charging port
• Charging status indicator
• Charging cable included

Actual operating time depends on speaker volume, communication frequency, battery condition, temperature, and charging conditions.

Shoulder-Mounted Clip Design

The rear clip allows the HB380 to be attached to a suitable shirt, vest, shoulder strap, belt, or equipment strap.

• Keeps the PTT button within easy reach
• Allows the radio to remain secured on a belt or equipment mount
• Suitable for mobile and hands-busy operations
• Reduces repeated handling of the radio

Coiled Cable for Flexible Movement

The approximately 1.2-meter cable uses a coiled section to provide flexibility while helping reduce excess loose cable during daily work.

How to Use the HB380

1. Charge the HB380 amplifier battery fully through its USB-C charging port.
2. Turn off the PoC radio before connecting the microphone.
3. Insert both pins of the K-type connector completely into the radio accessory port.
4. Attach the rear clip to a suitable shirt, vest, shoulder strap, or equipment strap.
5. Turn on the radio and confirm that incoming audio plays through the HB380 speaker.
6. Press and hold the side PTT button while speaking toward the microphone.
7. Release the PTT button to receive incoming communication.
8. Test the microphone, speaker and PTT function before professional use.

Frequently Asked Questions

Does the USB-C port connect the HB380 to a Type-C PoC radio?

No. On this HB380 version, the USB-C port is used only to charge the built-in amplifier battery. The radio connection uses the K-type two-pin plug.

Does the HB380 work with every K-type radio?

No. K-type connectors can use different wiring, audio levels, and PTT configurations. Compatibility must be confirmed using the exact radio model.

Does the microphone make incoming messages louder?

The HB380 uses a built-in amplifier and an 8Ω / 1W speaker to provide amplified incoming audio. Actual volume depends on the radio's output, volume setting, battery level, and operating environment.

Does the HB380 increase the communication range of my PoC radio?

No. The HB380 only provides external PTT, microphone, and amplified speaker functions. Communication coverage is determined by the connected radio, cellular or WiFi network, SIM service, and PoC platform.

Is the HB380 a Bluetooth speaker microphone?

No. It uses a direct wired K-type connection and does not require Bluetooth pairing.

Can it work without a PoC radio?

No. The HB380 is an external accessory and requires a compatible PoC radio to transmit and receive communication.

Does it work with Zello?

Compatibility with Zello depends on the connected PoC radio, operating system, application, connector wiring, and support for an external wired PTT microphone. Confirm compatibility with the exact radio model before purchasing.
