Hello everyone, I got few questions about M40, I just got mine today. I'll just add that I'm using Sound Blaster X-Fi Surround Pro 5.1 audio card. What I wanted to know is if they will be working okay with Jack to Optical audio cable ? I would like to buy one, as I have that port in my audio card and PS4. Also, while testing them I noticed one thing, when I try them out with some BlueRay movie and i turn on ANC I can see that sound is improving a lot, is louder and more detailed. The problem stats when I try to listen to music(mp3, flac) with ANC on, bass is is cracking on 100% audio and it stops when I go to 50%. Any solution to that or just my audio card is not good enough ? Greetings Jacob
