The price difference between the two is about 17%, making the Beta 91A the more economical choice for those on a budget.
Design and Build Quality
In terms of design, the Sennheiser E604 is built as a rugged instrument microphone, complete with three drum rim clips, making it versatile for various applications beyond just drums. It also comes with mic pouches and three 20-foot XLR mic cables, adding to its overall value. On the other hand, the Shure Beta 91A features a low-profile design that requires no external mounting hardware, making it easy to use directly inside kick drums. Both microphones are built to withstand high sound pressure levels, but the Beta 91A’s design specifically caters to bass applications.
Sound Quality
When it comes to sound quality, the Sennheiser E604 excels with its ability to capture frequencies between 40 Hz and 18 kHz at sound pressure levels exceeding 160 dB without distortion. This makes it ideal for instruments like drums, percussion, woodwinds, and brass. Conversely, the Shure Beta 91A is designed to deliver superior "attack" and "punch" specifically for kick drums, providing a strong low-end response that is tailored for heavy bass applications. Both microphones offer impressive sound quality, but their effectiveness largely depends on the intended use.
Versatility and Applications
The Sennheiser E604 is notably versatile, making it suitable for a variety of instruments beyond drums, including woodwinds and brass. This adaptability is enhanced by the included drum rim clips, which facilitate easy setup. In contrast, the Shure Beta 91A is specifically optimized for kick drums and similar bass instruments, making it a specialized tool rather than a multipurpose microphone. While the E604 can serve multiple roles, the Beta 91A's design means it excels specifically in bass-heavy environments.

The Sennheiser E604 is priced at $429.00, while the Shure Beta 91A comes in at $242.00, highlighting a significant price advantage for the Beta 91A. This price difference of about $187 makes the Beta 91A a more attractive option for musicians or sound engineers looking to equip themselves without breaking the bank.

On the flip side, the Shure Beta 91A is lauded for its low-profile design and ease of use, as it can be placed directly inside a kick drum. However, its specialization means it might not cater to those looking for a more versatile microphone option.
