Socket Mobile CX4681-3964 vs Socket Mobile CX4438-3627: Specification Comparison
Both the Socket Mobile CX4681-3964 and CX4438-3627 are handheld 1D/2D Bluetooth barcode scanners bundled with a charging dock, targeting retail, warehouse, and field inventory workflows. This comparison examines the three dimensions most likely to drive purchase decisions for mobile scanning deployments: ingress protection and environmental durability, Bluetooth radio technology, and package contents and compliance. Buyers choosing between these two models are trading off ruggedness level against wireless protocol generation, with meaningful operational consequences for each axis.
In This Guide
Which scanner handles harsher physical environments?
The CX4438-3627 carries an IP67 rating, meaning it is fully dust-tight and withstands water immersion up to 1 meter for 30 minutes per the IEC 60529 standard. This makes it suitable for environments with wash-down exposure, rain ingress, or submersion risk such as outdoor receiving docks or food-service warehouses.
The CX4681-3964 is rated IP54, which provides protection against dust ingress sufficient to prevent operational interference and against water splashing from any direction. IP54 is appropriate for general warehouse, loading dock, and light industrial use where the device may encounter splashes but is unlikely to be submerged.
For deployments where accidental drops into water, high-humidity cold storage, or wet processing areas are plausible scenarios, the CX4438-3627's IP67 rating provides a materially higher margin of safety. For standard dry-warehouse or retail floor use, IP54 is typically adequate.
Does the Bluetooth version matter for pairing and battery impact?
The CX4681-3964 uses Bluetooth Classic, the long-established wireless protocol widely supported across POS terminals, legacy Android handhelds, and Windows PC hosts. Bluetooth Classic offers robust, high-throughput connections and broad device compatibility across older host hardware.
The CX4438-3627 uses Bluetooth LE (Low Energy), a newer protocol designed to reduce power consumption on both the scanner and the host device. Bluetooth LE is natively supported on modern iOS, Android, and Windows platforms, but compatibility with legacy POS terminals or older Bluetooth 2.x hosts is not guaranteed without adapter support.
The choice of Bluetooth protocol is primarily a host-compatibility decision. Deployments anchored to modern mobile devices or tablets benefit from LE's lower power draw; installations built around legacy fixed POS terminals should verify host-side LE support before specifying the CX4438-3627. Neither scanner's spec sheet provides explicit battery capacity figures—both list 'Battery Life: Information' without a quantified runtime value.
Are there regulatory compliance or package differences to consider?
The CX4438-3627 explicitly lists RoHS compliance to EN 50581, the EU standard for restriction of hazardous substances in electrical equipment. This certification is relevant for deployments in EU member states or for customers with environmental procurement policies requiring RoHS-documented compliance.
The CX4681-3964 does not list a RoHS certification in the provided specifications. This does not confirm non-compliance, but buyers requiring documented RoHS certification for procurement purposes cannot confirm it from the available spec data and would need to request documentation from the manufacturer.
Both models are specified with identical package contents—scanner plus charging dock—and share the same 1-year warranty, USB and Bluetooth interface listing, and 1D/2D scan engine capability including UPC symbologies. No specification differences in package contents or warranty terms are present between the two units.
Which should you choose: the CX4681-3964 or the CX4438-3627?
Our take: The CX4438-3627 is the stronger choice when the deployment environment involves water exposure risk or when host devices are modern Bluetooth LE-capable platforms. Its IP67 rating versus the CX4681-3964's IP54 provides full dust-tightness and 1-meter water immersion tolerance compared to splash resistance only—a concrete durability delta that matters in cold storage, outdoor receiving, or food-service settings. Its Bluetooth LE radio reduces power overhead on both scanner and host relative to the CX4681-3964's Bluetooth Classic, and it carries documented RoHS compliance to EN 50581 where the CX4681-3964 spec sheet does not list this certification. The CX4681-3964 remains the appropriate pick where host hardware is limited to Bluetooth Classic—legacy POS terminals or older PC adapters—since LE compatibility cannot be assumed on those platforms. Both scanners share a 1-year warranty, identical package contents, and equivalent 1D/2D scan engine coverage.

Frequently Asked Questions
Which should you choose: the CX4681-3964 or the CX4438-3627?
The CX4438-3627 is the stronger choice when the deployment environment involves water exposure risk or when host devices are modern Bluetooth LE-capable platforms. Its IP67 rating versus the CX4681-3964's IP54 provides full dust-tightness and 1-meter water immersion tolerance compared to splash resistance only—a concrete durability delta that matters in cold storage, outdoor receiving, or food-service settings. Its Bluetooth LE radio reduces power overhead on both scanner and host relative to the CX4681-3964's Bluetooth Classic, and it carries documented RoHS compliance to EN 50581 where the CX4681-3964 spec sheet does not list this certification. The CX4681-3964 remains the appropriate pick where host hardware is limited to Bluetooth Classic—legacy POS terminals or older PC adapters—since LE compatibility cannot be assumed on those platforms. Both scanners share a 1-year warranty, identical package contents, and equivalent 1D/2D scan engine coverage.
Can I pair either scanner with an older Windows POS terminal?
The CX4681-3964 uses Bluetooth Classic, which is compatible with the widest range of legacy POS terminals and older Bluetooth adapters. The CX4438-3627 uses Bluetooth LE, which requires the host to support Bluetooth 4.0 or later with LE capability. Before deploying the CX4438-3627 with older fixed POS hardware, verify that the terminal's Bluetooth stack supports LE connections—this is not guaranteed on pre-2012 hardware.
Is the CX4438-3627 worth the upgrade for warehouse use?
If the warehouse environment involves wet floors, rain exposure, wash-down procedures, or potential drops near water, yes—the CX4438-3627's IP67 rating withstands full dust ingress and water immersion up to 1 meter for 30 minutes, versus the CX4681-3964's IP54 rating which covers dust interference protection and splash resistance only. For a dry, climate-controlled warehouse, the IP54 of the CX4681-3964 is typically sufficient and Bluetooth Classic may offer broader compatibility with existing infrastructure.
Do both scanners include a charging dock in the box?
Yes. Both the CX4681-3964 and the CX4438-3627 specify a charging dock as part of the package contents. Neither unit requires a separately purchased dock for basic charging, and both list USB and Bluetooth as interface options.
