What an awesome mic clip. It holds the mic great - slides and snaps on easy.

Sennheiser MD 421 Mic Stand Adapter

Fit perfectly, even though I had no idea what year production the mic was from. Fits all standard mic stands; single pole, boom stand, amp base, etc. Great price and excellent value. I have purchased items previously from Sweetwater and will continue to do so AND encourage my friends to shop there also.

Sennhieser MD 421 Mic stand adapter (mic clip)

Great piece, however it comes with the mini mic threads & it didn't come with the mini to regular size adapter to mount on a regular size mic holder. Currently I am unable to use it without the mini to regular mic stand adapter. Would be nice it they had identified that in the product listing OR...maybe they can send it to me after they read this review? Otherwise, its a good value & the customer support previously was great.

Sennheiser MD 421 Mic Stand Adapter Review

I know I'm not the first to say this, but I'll go through the motions: How could one of the world's greatest mic companies make such a great mic with such a dumb clip (or "mic stand adapter", as they call it)? This clip is a drag. It's unreliable, cumbersome, and breaks easily. But the mic is so worth it. It's one of the best mics in the world for putting in front of a guitar amp's speaker. But I've gotten great results using it to record acoustic guitar, fiddles, and all kinds of things including (believe it or not) VOCALS. So this clip is crap. Which is NOT Sweetwater's fault I hasten to add. This is just the clip you have to get to use the MD 421. In view of that, I'm frankly glad that Sweetwater carries it.

The MD421 is one of the classic multi use mics of all time. Built like a tank and it sounds great. Too bad that the love and forethought that went into the mic design didn't carry over into the clip. It is the most over engineered clip ever (moving parts!!!) and you STILL need a piece of E-tape on it to keep from accidentally unlocking it and sending the mice to the ground. Oy! You can't even use a regular generic clip to replace it. Oh well. Maybe that was the idea. After 40 years, I guess we are stuck with it.
