On-Stage HA4000 Reviews

It does the job

By Federico
Rated 4 out of 5

It does exactly what's expected. Two issues relating to my use: 1) Most of my headphones and earphones have 1/8 jacks. I need adapters for all of them. 2) I put this on the edge of my desk and when cables are plugged in, the cables' weight makes the unit topple over because it's so light.

Works perfectly

I use this for my live streaming business and works great.
