Too much tension
I've had a Blue Yeti microphone for a while, and I've been quite satisfied with it. When I was looking for a boom arm, I was concerned that the Yeti would be too heavy, so I thought I would be safe with a Blue arm. Unfortunately, the tension spring inside the arm was WAY too tight and the arm would drift upward from whatever position I put it in. There is an adjustment screw at the base that allows you to adjust the spring tension, but even at the least tense, the arm still wouldn't stay in place. I ended up returning it. I also agree with some other reviews about this arm that the tension knobs at the joints also required significant tightening and i didn't think they felt particularly sturdy. I was worried they would break at some point.
Fantastic!
This boom is fantastic. Great quality and easy to setup.
Love It!
Blue is a quality company and this boom is fantastic.
Disappointed
Looks good, price is attractive, easy to install but can't support more than a lightweight (nominal 12 oz) microphone. If a heavier mic is installed there isn't sufficient tightening available and the knobs break off! So, no big dynamics, ribbons of condensers: just toy electrets and cheapies, please. I know, I have three of these booms and they've all ended up with epoxied lower joints and broken knobs.
Too stiff
Was provided as a Kit with the Shure MV7. I think this arm may be expecting the heavier mic from Blue - With the adjusting knobs all the way tight, it was really awkward to position. I ended up using a small desktop stand.
Needs extension tube to work with SM7B
I purchased this arm because of its handsome construction and cable management, which I intended to pair with a Shure SM7B to give a more professional sound and appearance in zoom meetings. Unfortunately, the mount for the SM7B places the XLR port so close to the final knuck of the Blue stand that the XLR cable interferes with full range of motion of the microphone. In the attached picture, you can see that microphone is rotated about 30 degrees out of parallel with the boom arm and the XLR cable is touching the knuckle. The solution? A Shure Extenstion Tube, also available at B&H: https://www.bhphotovideo.com/c/product/68615-REG Some people complain that the boom arm, while handsome, doesn't hold it's position because the tension adjustment of the knuckles isn't strong enough. Experimentally, this is true; I can contort it into extreme positions and it wants to recoil into a more medium position, but practically, it hasn't been an issue for the zoom meetings in which I participate. I wanted a sturdy, handsome boom arm with discrete cable management and it's done what I need.
Ok Boom Arm
I'm using a Shure SM7B. The boom arm is very good looking and versatile. However, for some reason the one I got kept on rotating by itself to the right with any tiny movement. So when typing it'll rotating by itself which is very annoying.
Best arms for podcasting
