Frequently Asked Questions

The S50 band is more compact, so it’s best suited for environments with less RF congestion; a wider band would be preferable for very crowded spaces.
The SB900 is a proprietary lithium-ion battery, and while it offers extended runtime, replacements require ordering through Shure or authorized dealers – not something you’ll find at a convenience store.
The KSM8B offers a slightly more modern, defined sound with a tighter low-end compared to the Beta 87A’s warmer, more vintage character – both are excellent, but cater to different tonal preferences.
