Shure SM58 vs Audix OM5 Canada 2026
The Shure RPW112 is $205 CAD for Shure wireless users who want the familiar SM58 vocal sound on a compatible handheld transmitter. The Audix CAOM5 is $269 CAD for performers using an Audix H60 transmitter who need an OM5 capsule for that system. The main difference is system compatibility, not a minor upgrade choice. These capsule heads fit different wireless platforms, so your transmitter determines which one you can use.
Quick Verdict
Choose the Shure RPW112 if you own a compatible Shure handheld wireless transmitter and want the established SM58 element in your wireless mic. At $205 CAD, it is the practical replacement or spare for that setup. Choose the Audix CAOM5 if your system uses the Audix H60 transmitter and you specifically need its OM5 dynamic VLM capsule. It costs $269 CAD, but it is not interchangeable with Shure wireless hardware. Buy for transmitter compatibility first, then for your preferred capsule.

Sound and Performance
The RPW112 has a clear identity because Shure specifies that it uses the SM58 element. Its cardioid dynamic design is built around live vocal use, focusing on the singer while reducing pickup from sound arriving off axis. For performers and engineers familiar with the wired SM58, this is the useful part: the capsule is intended to bring that known vocal starting point to a compatible Shure wireless handheld.
The CAOM5 uses an OM5 dynamic VLM capsule in a modular adapter for the Audix H60. The supplied product information does not list its polar pattern, output level, frequency response, grille design, or feedback performance. As a result, it would be inaccurate to rank its vocal character against the RPW112 on paper. If you are already invested in the Audix H60 platform, the CAOM5 is the relevant OM5 capsule option. If you are comparing complete wireless systems, test both with your own voice, monitor level, and stage volume before treating the $64 CAD difference as a sound-quality verdict.
For working musicians, familiarity can matter as much as a stated specification. A singer who has used an SM58 for years may prefer the confidence of the RPW112's known element. An Audix H60 owner has a much simpler decision: the CAOM5 is designed for that transmitter. Neither product is a universal handheld microphone head.
Design and Build
Both products are replacement capsule heads, not complete wireless microphones. That distinction matters before you add either one to your cart. The RPW112 threads directly onto compatible Shure handheld wireless transmitters. It has an integrated grille with a built-in pop filter and capsule protection, useful for close vocal work and regular handling on stage.
The CAOM5 is a modular capsule adapter for the Audix H60 wireless transmitter. Its purpose is direct and system-specific: it lets an H60 user fit the OM5 dynamic VLM capsule to that transmitter. It is not a standalone microphone, and it does not make sense as a purchase for a Shure wireless owner.
Check the exact transmitter you own before ordering. A capsule must fit your wireless handheld to be useful, and these two products are designed for separate systems. For a venue, rental inventory, or touring setup, it can also be sensible to keep a compatible replacement capsule available for quick swaps.
Who Should Buy Each
- Buy the Shure RPW112 at $205 CAD if you use a compatible Shure handheld wireless transmitter and want the SM58 element in your wireless vocal setup. It suits singers, engineers, venues, and production teams that already know the SM58 sound and need a direct replacement capsule or spare.
- Buy the Audix CAOM5 at $269 CAD if you own an Audix H60 transmitter and want its OM5 dynamic VLM capsule. This is for performers committed to the Audix H60 platform. Confirm that you have the H60 before buying, because this capsule adapter is built for that system.
Alternatives Worth Considering
The alternatives below are complete wired vocal microphones, so they serve a different job than the RPW112 and CAOM5 capsule heads. They are worth considering if you need a dependable live vocal mic and do not need to attach a capsule to a wireless transmitter.
- Shure BETA 58A: At $245 CAD, this is for vocalists on loud stages who need a tighter supercardioid pattern and greater gain before feedback than a standard cardioid vocal mic.
- Audix OM7: At $359 CAD, this is aimed at very loud concert stages and performers who need strong feedback resistance. Its low output level requires a high-quality mixing console or preamp with sufficient gain.
- Shure SM58: At $149 CAD, this is the straightforward wired option for singers, rehearsal spaces, venues, and engineers who want the familiar SM58 vocal response and durable build.
The Bottom Line
For the Shure SM58 vs Audix OM5 Canada comparison, compatibility makes the decision. The RPW112 is the right purchase for a compatible Shure handheld wireless transmitter and costs $205 CAD. The CAOM5 is the correct option for an Audix H60 transmitter and costs $269 CAD. The Shure gives you the specified SM58 element, while the Audix provides the specified OM5 dynamic VLM capsule for its own platform. Match the capsule to your transmitter first. If you need a complete wired vocal microphone instead, the $149 CAD Shure SM58 is the lower-cost starting point.
