I expected more for the price point. I?ve been thinking a memory foam tip was my answer to keeping the pod from falling out of my ear, but maybe I don?t. They do a REALLY good job of producing multiple layers of sound. Then I turn on both speakers, and let them connect/sync to each other. Got these for my son as a present , he is a 7. This is a great pair of cheap headphones for someone who1. It looks awesome. I do wish wheels were included as an option. Las caracteristicas físicas y funcionalidad son excelentes. Very disappointed got double of the same spice and some were not even labeled so who knows what they are like the shelving it came with that?s all
