I asked several audio savvy people about Astro A50s and I was recommended to go with more expensive Sennheiser 650 or 600 as their specs are excellent and supposedly way better for music and movies. I mostly game and watch movies. I care for quality a lot but I also care about positioning. I know the whole Dolby Digital is a bit of a gimmick because sound waves are always analogue, so A50s conver digital to analogue as the last step. I still went with Astros because I did not have Asus Xonar or similar card with Dolby Headphone support. I get Dolby Digital Live 5.1 with great positioning. But what advantage do they have over the pro sets like more expensive Sennheiser series headphones?
