Allow me to say that this is a brilliant review, very well done and you have fantastic hair. I hear very good things about Audio-Technica and feel that I should switch to their headphones from my current ones.
I have a question, if someone can please answer it. I have the Astro A40 headset and really want to do an upgrade (probably shouldn't but still want to). I'm leaning heavily towards the AD900X and wonder if the switch will be an "up" grade or a "lateral" grade.
Thank you! I never know what to think when people comment on the hair lol.
I'm afraid I haven't heard the headphone that you have at the moment. They will definitely sound different since the AD900X is open. What are you looking for in a sound?
