It's the perfect utility for making sure when plugging and unplugging headphones that the audio stays centred.

Great solution to a problem which should not exist

I once spent a good couple of hours trying to determine why I had no audio on the left channel of my stereo. I checked cables. I checked speakers. I very nearly came to the conclusion my amplifier was broken. Once I realized that my mac likes to let the balance controls drift until I only have audio in one channel, I was a bit peeved. This is a really silly bug.

The good news is, this application keeps the balance set where you want it. An excellent workaround.

Worth the cost to work around annoying macOS bug

While I really wish Apple would fix this bug in macOS, this tiny little app has saved my sanity for several years and is worth every penny.

Glad I didn't have to make this myself

Exactly what I needed. Been planning on writing an app like this but I'm glad somebody else did first!
