Will post some of the conclusions I have come to this far of these two noise cancelors versus the AKG and a Sound blaster portable E5 headphone amp.

May take a while I'm not doing it all in one go.

There's a ton of comparisons on YouTube. Literally loads. But what I will say about the Sony's just hasn't been made so obvious anywhere else I have seen.

Since I literally really don't give a damn the truth will come to the fore. I am not an online headphone reviewer relying on being sent samples.
