Customer Review Summary

The Heil Sound PR37

The build quality is robust, housed in durable metal, and it comes in environmentally friendly packaging, which is a nice touch. Upon first use, the microphone elicited a ‘WOW’ response, showcasing its superior performance compared to other well-known brands.

For those transitioning from other microphones, the PR37 represents a significant upgrade. It offers a clearer and more voluminous sound, making voices more intelligible and airy. The microphone’s design is particularly effective in smaller venues, reducing bleed from other sound sources.

While the included clip may feel a bit cheap, it serves its purpose, and replacing it is straightforward if needed. The microphone’s handling noise is minimal, with excellent plosive management when used with a pop filter, although the windscreen provided could be improved.

In terms of versatility, the PR37 performs admirably not just for vocals but also for recording acoustic instruments, making it a valuable addition to any setup. The high output level, crisp sound, and punchy low-mid response make it suitable for both live performances and studio recordings.

Overall, the Heil Sound PR37 has proven to be a top-tier microphone, highly recommended for anyone looking to elevate their sound quality. It stands out in a market filled with standard options and truly deserves recognition.
