Hello! Thanks for reading and for the reply!
I’d love to give you a comparison between the two Pioneers…but I still haven’t had the chance to listen to the HRM-6. I’m sorry! I can say that the HRM-5 is a very good value, and if you asked me whether I’d want to mix with that or the M40X, I’d pick the HRM-5 every time for its slightly flatter response and its superior comfort for long sessions.
I’m sorry again that I can’t provide more info. The HRM-6 has been on my wishlist for a while, but it’s not the easiest pair to come by! They sell out on Amazon pretty quickly.
Thanks again for your time!
