I use Comets along with the Westone Bluetooth dongle as my 5x5 gym companion and twice weekly mountain biking earbuds. They're great! They sound deep and rich and give my workout tracks enough body but also have some fair bit of sparkle up top. I wear them down rather than over ear. My only complaint—and it also holds true with the Atlas—is that no matter what, these don't seal nearly as well as my SE846s did. Meaning, I always hear wind when I'm mountain biking, and I always get a bit of outside noise making its way in. I tried every tip, even bought Comply large size foam tips, and they just don't isolate nearly as well as the SE846s, which pretty much blocked out existence itself. Again, minor quibble, and it's something I never would have thought about, but something I definitely noticed. Complaint aside, they make great exercise earbuds, and when I'm struggling on the squat rack AC/DC's Thunderstruck really sounds motivating out of them.
