Arrowmax APM250-K2 Waterproof Shoulder Speaker Microphone - 4 Pack

In this review the Arrowmax APM250-K2 shoulder speaker microphone kit is judged as a practical, workhorse accessory for teams who use Kenwood two-way radios with a 2-pin universal connector. The bottom line: this 4 pack is for crews that need loud, clear transmission and a weather-proof clip mic without fuss; the review finds the microphones deliver immediate, intelligible audio and a sturdy 360 tightened lapel/shoulder clip that holds up in rough conditions. If compatibility with specific Kenwood and NEXEDGE models is met, the value per unit is notable.

Key Features

• Wide compatibility: Works with Kenwood radios that use the 2-pin universal connector including many NX series models, making deployment across mixed fleets simple.
• Clear, loud transmission: The microphone is designed for crystal clear, LOUD and instantaneous voice transmission so messages come through on first push.
• Weather-proof design: The IP56-style, extreme duty construction protects the mic in wet or dusty environments so it survives outdoor and industrial use.
• Secure clip: A 360 tightened lapel and shoulder clip keeps the microphone positioned reliably during movement and active shifts.
• Built-in 3.5mm jack: Accepts a 1-way earpiece so users can add discreet listening when privacy or noise reduction is required.

Who It's For

The APM250-K2 4 pack is aimed at security teams, event staff, construction crews, and any group that uses compatible Kenwood or NEXEDGE radios and needs a simple, rugged remote microphone. Buying four at once suits small teams or organizations outfitting multiple radios at a time.

Users who should look elsewhere include owners of Kenwood models with the 14-pin universal connector or other proprietary plugs, and those who require a two-way earpiece with inline PTT and full duplex audio instead of a one-way earpiece option. Also check compatibility carefully for NX-3200, NX-3300 and similarly numbered models which are not supported.

Pros & Cons

Pros

• Robust, weather-proof construction suitable for outdoor and industrial work.
• Strong, clear audio output that reduces the need for repeated transmissions.
• Convenient 3.5mm jack for adding a professional 1-way earpiece when needed.
• Cost-effective 4 pack simplifies outfitting multiple users at once.

Cons

• Not compatible with Kenwood models that use the 14-pin connector, so exact model matching is required.
• The product is a one-way earpiece setup; users wanting two-way earpieces must source different accessories.
