After getting my second KM184 my steel pan recordings just opened up. I really enjoy these. Thanks to Jeremy for all the great customer support

Rig. Acoustic Guitar-neumann-mogami gold cable-beringer phantom power-mogami gold cable- fishman solo amp. I NEEDED this mic! So when sweetwater announced their fantastic financing I jumped on it. All the sweetwater reviews are pretty much on target. It's far and away the best mic I've ever owned (and the most costly) I look at this mic as an instrument unto itself. An investment quality mic. If you want the sound of your guitar and nothing but and are uber critical of your sound, take the plunge.Sure enough, it came in a cardboard box. Two reasons why this might be. 1. Neumann figured this mic would go into a studio mic locker or something similar and there would be no need for a cheap bag. 2. Nothing about the Neumann company is cheap, so to include a protective case would certainly add to the cost.Ryan Sloan my sales rep got it delivered to my door in 24 hrs, and I received it on my birthday! How cool is that. Sweetwater rocks!

Neumann KM 184

I purchased this mic after buying my first instincts couldn't have been better. This is by far the best pencil style condenser I've ever used. I love it on the Hi-Hat, Acoustic Guitar, and recently used in recording a church choir. Don't think twice on this one.

Cardboard case? Really?

I just received my KM 184 and I was shocked that it comes in a cardboard box. I bought a Blue mic for around $200 and it had a wooden case. I guess I can be thankful it didn't come in a paper bag, but I really expected more from Neumann for an $850 mic.

Love my KM 184's

Absolutely magical on acoustic guitar. The clarity will blow you away. Good for overheads, great for hat.

Sweetwater Advice

Paul Lea

Look no further if you are in search of a solid and reliably great sounding mic for your acoustic guitar. It also works great on classic "blackface" guitar amps.

Stuart Niven

The Neumann KM 184 is an essential microphone for any recording engineer's microphone cabinet. Simply wonderful on acoustic guitars with a very detailed and clear articulation. On cymbals it shines, bringing out the natural presence and shimmer, making you think that you are right there in the room as it was recorded! Wow! Pick up a pair of these and you have a killer pair of overhead microphones!

Jeff Barnett

A classic. The KM 184 is a standard fixture in any serious mic collection. It's the quintessential mic that other small-diaphragm microphones seek to emulate.

Kyle Manship

A first physical encounter of the KM 184 can be deceiving. It's a small and lightweight microphone, unlike its sound. Based on the legendary KM 84 from 30+ years ago, the KM184 continues the legacy of Neumann's professional and ear-pleasing products. Based on the same capsule design and size as the KM 84, the KM 184 is a perfect addition to any home or professional recording studio, as well as the touring musician. This microphone is renowned for drum overhead and hi-hat applications. The frequency response is flat and smooth. Despite being a +48V Phantom-powered tubeless microphone, it still retains tube warmth and fullness. It is detailed and clear across its frequency spectrum. Hearing this microphone for the first time on acoustic guitar just flat out blew me away. It sounded so huge and warm, yet accurate and detailed. It requires little to no EQ, even on a less than stellar instrument. As a stereo pair in an X/Y application on drum overheads, the KM 184 reproduces an outstanding stereo image and clarity to a drum set, capturing every nuance of the slightest crash and accent. The KM 184 is an outstanding upgrade at an even better price point for the home studio owner. This will definitely take your tracking and finished products up exponentially in quality. The KM 184 is a standard in all professional recording studios and is a must for any audiophile.
