Our take on the Sennheiser MD 421-II
The Sennheiser MD 421-II is a large-diaphragm dynamic XLR mic, suited to streamers with an audio interface.
The tracked price is $429, the top of a $395.12 to $429 range across nine points from August 26 to October 19, 2026. That is nearly $34 above the low, so a sale is worth waiting for. The listing gives a five-position bass roll-off switch and a large dynamic element that handles high sound levels. The description says it has been used for guitars and drums for over 35 years. It is wired through XLR, so you need an interface or mixer. Rated 4.5 across 140 retailer ratings.
