Additional Information

Customer Review Summary

The Warm Audio WA-87 R2B microphone delivers a sound that is truly “larger than life”, offering a beautiful presence that is less nasal than its counterpart, the U87AI, yet retains a similar tonal quality to that of a Neumann. Its versatility is enhanced by multiple polar patterns and a -10dB pad, making it suitable for various recording scenarios.

The microphone boasts excellent build quality, coming with a wooden box, a sturdy suspension mount, and spare elastic bands, although the heavy weight of the mic does necessitate a robust stand. It is noted for its impressive sound on male vocals and acoustic guitars, providing a clean and warm tone that is particularly pleasing for higher vocal ranges, such as alto and soprano, without harshness in the high frequencies.

Despite its larger size and weight, which can make it challenging to balance, the WA-87 R2B’s sound quality is reported to rival that of more expensive microphones, making it an outstanding choice for both beginners and seasoned audio engineers alike. Some users have noted minor issues with the alignment of the switches, but these are seen as negligible compared to the mic’s overall performance.

Overall, this microphone has quickly become a favourite for studio use, praised for its rich, warm sound and high-quality construction, making it a must-have for anyone looking to elevate their recording setup.
