## Description

## How it fits
If you need to connect a compatible HyperX microphone to a boom arm, this SUNMON adapter is made for that mounting task. It fits the HyperX QuadCast, QuadCast S, and DuoCast. Its 3/8-inch connector is designed for use with most microphone boom arms that use a 3/8-inch thread. That gives you a practical replacement when the original mounting adapter is missing or needs to be replaced.

For setup, attach the adapter between the microphone and a compatible 3/8-inch boom arm. The adapter is the connecting piece, the microphone and boom arm are separate components. Confirm that your arm uses the specified thread size before installation, then rotate the adapter into place to make the connection.

## Benefits
The adapter helps restore a boom-arm mounting setup without requiring a different microphone. Its stated compatibility covers three HyperX microphone models, making it useful for a QuadCast, QuadCast S, or DuoCast setup. If you already have a 3/8-inch boom arm, this adapter provides the connection point those microphones need for that arrangement.

The body is made from hard plastic, with a metal nut in the center. The metal nut is intended to help prevent wear to the plastic during rotating installation. This combination keeps the mounting component focused on its role: connecting the microphone to the arm while supporting repeated attachment and removal.

Buyers describe the adapter as a useful replacement and mention that it works with the QuadCast. That feedback may help when choosing a replacement part, while compatibility for your own setup depends on using one of the listed microphones and a matching 3/8-inch boom arm.

## Practical questions
Which microphones does this adapter fit? It is designed for the HyperX QuadCast, HyperX QuadCast S, and HyperX DuoCast, so it can serve as a replacement mounting adapter for any of those models.

What boom arm thread does it use? The adapter has a 3/8-inch connector and is intended for microphone boom arms with a matching 3/8-inch thread. Check the arm’s thread size as part of setting up the connection.

What comes with the adapter? One QuadCast adapter is included. The microphone and boom arm are not included, so use it with the compatible microphone and boom arm you already have.

## When it makes sense
Choose this adapter when your HyperX QuadCast, QuadCast S, or DuoCast needs a mounting connection for a 3/8-inch boom arm, particularly if you are replacing a missing adapter. It is a focused alternative to replacing the microphone or changing your mounting setup: the adapter supplies the connection between the listed microphone and a compatible arm. For a desk setup where the boom arm is already in place, it provides a straightforward way to complete that mounting arrangement.
