Awesome Alex I love customs over universals, they do take some getting used to at first.

Cool! I've heard ACS also make great ones like these.

Thanks for the review! Do you have any experience with how they react to perspiration? I use my W40s for (light) gym workouts. And with any non-foam tips I have tried so far, they become "vacuum sealed" after a bit... sounding bad and feeling bad. So I am constantly having to take them out and put them in again Right now, I am relatively happy with Comply. But I have an asymmetry that makes one ear prone to falling out... so would love to find a better solution. Thanks again for the great review! This is a product that has been on my mind since I learned of it.
