Best praise vs top criticism for Technics EAH-AZ40M2
“I just bought a pair of Technics Az40m2s on Amazon for 100 bucks. I lost my Bose Quiet Comfort 2s and didn't really have a budget for a replacement pair. They're pretty solid. The sound is almost as good if not a little better. They're definitely flatter sounding, which I personally like, but with the app in dynamic mode they sound nice. The noise cancelling isn't as good as the quiet comforts but they're not the Az60 or Az80s. I'd recommend them. Not a bad choice for 100 dollars or so.”
“The AZ40 is missing features like wireless charging and has lower battery life. Indeed, the only difference between the AZ80 and AZ60M2 is the size of the driver. At the time of my purchase, there was a $75 difference between the 2. I'm really happy with my purchase though.”
