Socket Mobile CX4528-3769 vs Socket Mobile CX4438-3627: Specification Comparison
Both the Socket Mobile CX4528-3769 and CX4438-3627 are Bluetooth LE, IP67-rated handheld 1D/2D barcode scanners positioned for retail point-of-sale, warehouse, and field inventory use. They share the same scan engine class, wireless interface, ingress protection rating, one-year warranty, and RoHS compliance standard. This comparison examines where their documented specifications diverge across symbology breadth, platform compatibility, and included accessories to help buyers select the right unit for their deployment.
In This Guide
Which scanner covers a broader range of barcode symbologies out of the box?
The CX4528-3769 lists an explicit set of supported symbologies: QR Code, Data Matrix, PDF417, Code 128, and Code 39. This covers the most common 2D formats used in retail, logistics, and document workflows, as well as two widely deployed 1D linear codes.
The CX4438-3627 lists only UPC under its symbologies specification. While its marketing description references '1D/2D barcode symbologies,' the structured specification field documents only UPC. Buyers requiring verified support for QR Code, Data Matrix, PDF417, Code 128, or Code 39 cannot confirm coverage from the provided spec data for this model.
For deployments that must scan mixed-label environments including 2D matrix codes or PDF417 shipping labels, the CX4528-3769 provides documented multi-symbology support. The CX4438-3627's spec sheet does not substantiate equivalent coverage.
Which scanner offers documented platform and device compatibility?
The CX4528-3769 explicitly lists iPhone 16 as a compatible device and designates its scan range as mid-range. It also documents both USB and Bluetooth LE interfaces, with a note that no specialized drivers are required for most deployments — a relevant operational detail for IT and POS administrators managing rollouts across mixed hardware.
The CX4438-3627 lists no specific compatible device in its specification data. It shares the same USB and Bluetooth LE interface set and the same 'no specialized drivers' characteristic as implied by its interface listing, but the absence of a named compatible platform leaves host-device compatibility unverified from the provided specs.
For organizations standardizing on iPhone 16 or requiring pre-validated mobile pairing, the CX4528-3769 carries explicit documentation. The CX4438-3627's compatible device field is not populated in the provided specification set.
Which scanner includes accessories relevant to depot or counter deployments?
The CX4438-3627 documents a charging dock in its package contents, included alongside the scanner itself. A charging dock is a meaningful operational inclusion for counter or depot deployments where the scanner sits idle between uses and must maintain charge without manual cable management.
The CX4528-3769 does not list a charging dock or any bundled accessory in its specification data. Whether a dock is available as a separate purchase is not addressed in the provided specs.
For stationary or semi-stationary deployments — such as a staffed POS counter — the CX4438-3627's included dock reduces day-one accessory procurement. For mobile or roving use cases where a dock is unnecessary, the dock's absence in the CX4528-3769 package has no practical impact.
Which should you choose: the CX4528-3769 or the CX4438-3627?
Our take: The CX4528-3769 is the stronger choice when verified multi-symbology coverage and named device compatibility are non-negotiable deployment requirements. It documents five distinct symbologies (QR Code, Data Matrix, PDF417, Code 128, Code 39) versus the CX4438-3627's single documented symbology (UPC), and explicitly names iPhone 16 as a validated compatible device — a specification the CX4438-3627 does not provide. Both units share IP67 ingress protection, Bluetooth LE, USB, one-year warranty, and EN 50581 RoHS compliance. The CX4438-3627 differentiates itself by including a charging dock in the package, which the CX4528-3769 does not list. Buyers deploying at staffed POS counters who need a ready-to-charge cradle and whose label mix is primarily UPC may find the CX4438-3627 sufficient; those scanning mixed 1D/2D label environments or deploying on iPhone 16 should select the CX4528-3769.

Frequently Asked Questions
Which should you choose: the CX4528-3769 or the CX4438-3627?
The CX4528-3769 is the stronger choice when verified multi-symbology coverage and named device compatibility are non-negotiable deployment requirements. It documents five distinct symbologies (QR Code, Data Matrix, PDF417, Code 128, Code 39) versus the CX4438-3627's single documented symbology (UPC), and explicitly names iPhone 16 as a validated compatible device — a specification the CX4438-3627 does not provide. Both units share IP67 ingress protection, Bluetooth LE, USB, one-year warranty, and EN 50581 RoHS compliance. The CX4438-3627 differentiates itself by including a charging dock in the package, which the CX4528-3769 does not list. Buyers deploying at staffed POS counters who need a ready-to-charge cradle and whose label mix is primarily UPC may find the CX4438-3627 sufficient; those scanning mixed 1D/2D label environments or deploying on iPhone 16 should select the CX4528-3769.
Is the CX4528-3769 or CX4438-3627 better for scanning shipping labels with QR codes or PDF417 barcodes?
Based on the provided specifications, the CX4528-3769 is the documented choice. It explicitly lists QR Code, Data Matrix, and PDF417 among its supported symbologies. The CX4438-3627 lists only UPC in its symbology specification, so support for 2D matrix and stacked linear formats cannot be confirmed from the available spec data.
Does either scanner come with a charging dock included?
Yes — the CX4438-3627 lists a charging dock under its package contents. The CX4528-3769 does not include a charging dock in its documented package contents. Buyers who need a dock for the CX4528-3769 should verify separately whether one is available for purchase.
Which scanner is confirmed compatible with iPhone 16?
The CX4528-3769 explicitly lists iPhone 16 as a compatible device in its specifications. The CX4438-3627 does not list a specific compatible device in the provided spec data, so iPhone 16 compatibility for that model cannot be confirmed from the available specifications.
