Well I got my M100 two days ago, and they are absolutely gorgeous. The only concern I have is the reason I bought the headphone was because I'm a huge EDM fan and bass head, hoping to get some really good beats from it. Being a beginner, I don't really know how long it takes for headphones to burn in. The amount of hours played would be over 24 hours, and I'm not satisfied. My Astro A50's sound extremely better with bass. It's brain melting and very punchy, making me very disappointed when I listen to the M100's. I have one or two songs that sound decent when is comes to bass, but 60+ songs I have sound flat compared to the giant bass sound the Astros give me. Am I being impatient? Will the bass quality get better over time? If it doesn't, I'm afraid that I'm going to have to refund the M100's and get something to satisfy my needs. I'm praying that I'm just being impatient and that the full burn in hasn't happened. They are really good looking headphones and I'd hate to refund them. Thanks!
