I have a collection of headphones and iems that is probably unhealthy, but we are not here to talk about that. Instead, I came into work and realized I've been using the same KZ-zs10 pros for a few years of zoom (has a mic on the wire), music, and whatever else at work with no complaint.

Given all the other options out there, or that I own, it surprises me that such a humble iem has performed so well. Which brings me to my question: what is your old reliable? Your everyday workhorse? What headphone or iem do you reach for over and over again?
