Hall of Fame Mic

This mic is awesome. I have only used it on vocals. On vocals it knocks them out of the park! You can track vocals on these and hardly need to do any EQ after. I recently tracked on this mic and loved the chain I was able to use this M149 to a BAE 1084 and a EL Distressor (Compressor). Boy did the final product sound incredible. Plain and simple with this mic you get what you pay for!

My desert island mic

This mic is absolutely killer! I've used it on about everything from drum rooms, vocals, claps, gang vox, and ukulele! It brings huge, warm, crisp sounds. It's worth every penny.


All I can say is if GOD needed a microphone to talk to us or sing, this would be itamazing,

Excellent mic from Neumann!

This is my go-to mic for just about everything. Capture every little nuance of vocal performances. I even use a pair as ambient mic'ing above the drum kit for stellar results.

Sweetwater Advice

Kenny Bergle

What can I say? Possibly the 'best' mic on the planet! Sounds GREAT on anything, REALLY! I own a pair and they are worth every penny. The M149 made me a better engineer instantly as it erased a ton of microphone-related issues and eliminated the need for audio band-aids right and left! You will NEVER be sorry you bought an M149, except possibly that you didn't buy a pair! REALLY!

Jeffrey Green

The M149 is the must-have studio microphone for the serious recording engineer or studio. One listen to this mic and you'll hear a unique, smooth, warm, refined quality that is not present in any other microphone.
