Retevis RB37 Bluetooth Walkie Talkies 4-Pack - Ready-Paired Radios

In this review the Retevis RB37 Bluetooth walkie talkies stand out as a practical four-pack for teams that need hands-free, reliable short-range voice communication. The single biggest reason to buy is the factory-paired Bluetooth earpiece and radio pairing that reconnects automatically after power-up, which saves time for busy shifts in schools, hospitals, retail floors, and manufacturing sites. The RB37 pairs quickly within about 6m, offers a robust 2000 mAh battery for long standby, and includes both Type-C and charging base options that suit multi-shift use.

Key Features

• Auto-paired Bluetooth: Each walkie and its wireless earpiece arrive paired so devices typically reconnect automatically after turning on, cutting setup time.
• Long battery life: A 2000 mAh rechargeable cell delivers roughly 120 hours standby and recharges in about 5 hours by Type-C or charging base for flexible charging routines.
• Hands-free VOX: A 0-9 level VOX setting can be enabled so users can operate hands-free without repeatedly pressing PTT, useful during patrols or managing tasks.
• Built-in flashlight: The large-diameter light turns on with a 2 second press of the PF2 button and provides emergency illumination in dark areas.
• PTT on headset: The compact Bluetooth earpiece includes a touch PTT key and separate volume controls, letting users talk or adjust sound without touching the radio.
• Compatibility and channel lock: RB37 directly talks with other Retevis FRS radios on channels 1-5 and supports a channel-lock feature via firmware activation to prevent accidental channel changes.

Who It's For

The RB37 four-pack is aimed at small teams in environments where quick deployment and hands-free communication matter, such as school security teams, retail floor managers, facility maintenance crews, and light manufacturing lines. The ready-paired earpieces and long battery life make these radios especially useful for multi-shift staff who need dependable reconnection and minimal daily setup.

Those who should look elsewhere include users who require very long range professional radios, advanced encryption, or model-specific third-party accessory ecosystems; the RB37 is optimized for short to medium range FRS-style use with Bluetooth headsets and practical on-site features rather than heavy-duty long-range coverage.

Pros & Cons

Pros

• Ready-paired Bluetooth earpieces that auto-reconnect for fast setup.
• Two charging methods (Type-C and charging base) and long standby time support long shifts.
• Hands-free VOX and headset PTT give flexible communication styles.
• Built-in flashlight adds safety value for low-light tasks.

Cons

• Sound and effective range vary with distance, terrain, and weather, so results depend on the environment.
• Channel-Lock requires firmware activation, adding a step for administrators who want to restrict channel changes.
