In a perfect world, everyone would have great headphones—the would fit perfectly, have great sound, and, most importantly, they would all be the same.
But that's not reality for me and many other podcasters. Most of the time, we each have our own headphones that fit our ears best (or else our budgets). You can use a simple headphone splitter, like I shared yesterday, but I recommend something like the Behringer HA400.
A headphone amplifier like this is not subject to signal-weakening when you add more headphones. But more importantly, this gives each output channel its own volume controls.
So now everyone can wear their favorite pair of headphones and
eat their cake control their volume, too!
