FAQ

What's the difference between EM-9001M and EM-9001M-E?

Same electronics and Bluetooth feature set; EM-9001M-E is a compact/low-profile shell variant of the same design — check the separate EM-9001M-E product page for its specific published numbers.

How is this different from EM-9001C?

EM-9001M actively compresses/amplifies ambient sound in addition to Bluetooth; EM-9001C is described by the manufacturer as an "electronic earmuff with compression" with a similar but separately-rated shell (SNR 28dB / NRR 22dB) — see the EM-9001C product page for its own numbers.
