Detail 01
Extendable length

1/3
Independent shopping perspective
The Korena take
Extendable boom arm in black, for mic setups where the reach needs to change — studio, broadcast, or a shared console position.
Strong match
Who this is for
- Studio desks where mic distance changes between sources or sessions
- Reaching over a console or drum kit from a fixed mount point
- Setups shared by people of different heights and seating positions
Consider the trade-offs
When to look elsewhere
- Anyone wanting a complete stand out of the box
- Fixed single-position setups where extension adds no value
- Chrome or lighter-colored rigs where black would stand out
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
No counterweight
Balance comes from your mount and mic clip. Extended far out, a heavy mic will pull the arm down.
Detail 03
Ebony (black) finish
Stays visually invisible on camera and under stage lights.
Detail 04
Boom arm only
Needs a compatible base, desk mount, or stand — this is the horizontal section.
Detail 05
Longer reach than the mini boom
Lets the base sit off to the side, out of the player's or host's way.
Final check
Know before you order
- 01No base, mount, or mic clip in the box — plan for those
- 02Fully extended, a heavy mic needs a solid, weighted base to stay upright
- 03Confirm the thread size matches your mount and mic clip
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is a base included?
No. This is the boom arm alone. You'll need a base, desk mount, or stand for it to attach to.
02How far does it extend?
It telescopes to change reach. Extended fully, it puts the mic well away from the mount point; retracted, it works close in.
03What is the difference between the ebony and chrome versions?
Finish only. Ebony is black and stays visually discreet; chrome is bright and matches polished hardware.
04Does it hold a heavy mic?
There's no counterweight, so a heavy mic extended far out will want to droop. Use a heavy base and keep the arm shorter with big mics.
