These things can’t handle anything, and that’s why I love them
I can hear any problems with my mix immediately when I listen to it on these puppies. They can handle only the bare minimum of bass, they accentuate any honk or boxiness that any instrument may have, and all around are great at catching problems.
This is how a lot of people are going to hear your music for the first time.
Unless you have a multimillion dollar marketing budget, a lot of people are going to hear your tracks on crappy computer speakers. Get an idea of what it will sound like to them and adjust your mix accordingly.
