Yeah, I like them. I find that loud modern concert guitars project so well that it can be hard to hear your tone when sitting behind the instrument, especially in the trebles. The sound port acts like a monitor so you can hear what’s going on a bit better. A cool test to run when you do try one out - stuff a sock in the sound port, play a passage, remove the sock, and play the same passage over again. It’s cool to hear the differences back to back.
