HYTERA EHS24 C-style earbud with inline microphone, PTT and 3.5mm 4-section single pin for PDM680/PNC460/PNC550/PNC560

Wired C-style earbud HYTERA EHS24 provides discreet audio monitoring and push-to-talk control for compatible two-way radios. The accessory combines an earbud speaker, an inline microphone and a PTT button with a 3.5 mm 4-section single-pin connector designed to interface with HYTERA models PDM680, PNC460, PNC550 and PNC560. The compact C-style design sits comfortably behind the ear for extended wear and enables private communications in professional environments such as security, events and retail.

Advantages

The HYTERA EHS24 integrates listening, speaking and transmit control in a single wired unit that minimizes handling of the radio. The inline microphone captures voice close to the user for clear transmission while the dedicated PTT button allows fast, reliable control of the radio without reaching for the main device. Its 3.5 mm 4-section single-pin connector ensures compatibility with the listed HYTERA models and provides a secure electrical connection for audio and PTT functions.

Suitable for

• Security personnel and guards requiring discreet communications
• Event staff, ushers and stage crews coordinating activity on site
• Retail staff and hospitality teams needing hands-free call handling
• Field technicians and delivery personnel working in noisy or crowded environments

When it may not be suitable

The EHS24 is a wired accessory intended specifically for compatible HYTERA radios; it will not function with devices that lack the 3.5 mm 4-section single-pin interface or with generic 3.5 mm audio jacks. It is not a noise-cancelling headset and may be less effective in extremely loud environments where specialized noise-reduction headsets are required.

Key specifications

• Form factor: C-style single earbud with behind-the-ear fit
• Microphone: inline microphone integrated into cable
• Control: inline push-to-talk (PTT) button on cable
• Connector: 3.5 mm 4-section single-pin connector for compatible HYTERA radios
• Cable: fixed wired cable for audio and control signals

How to use

Connect the 3.5 mm 4-section single-pin connector to the accessory port of a compatible HYTERA radio (PDM680, PNC460, PNC550 or PNC560). Place the C-style earbud behind the ear and adjust for comfort; position the inline microphone near the mouth but not directly against the skin to avoid breath noise. Use the inline PTT button to transmit; release it to return to monitoring. Store the earbud in a protective pouch when not in use and avoid pulling on the cable to prolong service life.

What to consider before purchase

• Confirm radio compatibility: intended for HYTERA models PDM680, PNC460, PNC550 and PNC560
• Wired connection: ensure a wired accessory meets your mobility needs
• Single-ear design: suitable for one-ear monitoring, not stereo listening
• Environment: not optimized for very high-noise settings requiring active noise cancellation

Usage recommendations

For reliable, discreet communications, route the cable to avoid tangles, keep the inline microphone clear of clothing friction, and test PTT operation before starting a shift. Replace the ear tip if worn and store the accessory protected from moisture and extreme temperatures.
