The one con i found was that the product is very flimsy. Trying to get the company to replace it! I ordered mine in my normal size after reading all the Reviews and they fit perfect. I sacrificed some sound quality for the features it is providing. They both work well. Slide open, find the Bluetooth connection in phone, DONE! and now its made my airing down more of a headache. But I can’t wait them for longer than 2-3 hours of activities with intermittent walking (church, concert, date night, etc. No pain on break-in, comfortable from the very first time I wore them. The silicone is a good thickness.
