Stellar review, being complete, detailed and spot-on. Congratulations! After some time with the Pistons I find your review to coincide with my thoughts entirely. They seem a special value to become an all around IEM, you can lug around daily. Maybe the magic is that they don't offend much, they fit in without discomfort and have no blaring sound flaws. I look forward to your review on the Piston 4.
