I tried out the Dolby Access app from the Windows store with my headphones (Hifiman HE-400i) today on a colleague’s recommendation. It doesn’t seem to make a lot of difference to the sound for my headphones. When it comes to music there is no difference at all, but for gaming, I do feel there is some improvement in positional accuracy. I’ll test this out a bit in in the next few days. They offer a 7-day free trial, and it’s a one-time payment for the app. No subscription. I’ll keep this post updated.
The HE400i is a great pair of headphones btw. I’ll write about it sometime. Music sounds beautiful on these open back cans.
Update: I did not get the subscription. The app improved positional accuracy, and that’s about it. No other benefits on my headphones. It depends a lot on what headphones you’re using. The person who recommended it to me has the Audio Technica ATH-M30x, and what he got is a much better soundstage and better detail in general.
