This article is nonsense. Fewer teeeters and fewer microphones. So what? We have no idea if they are fewer but much higher quality tweeters. We have no idea if the microphones are better or worse. Spec sheets are not the end of experience.
The only thing we know is that the wifi is worse but given that the data being carried is only music and so small maybe that makes it play better with thread or doesn’t make any difference because of the data. On paper it looks “worse” but might be meaningless.
I don't think the article is nonsense. That's simply MR reporting facts.
What is nonsense are the conclusions drawn by most of the commenters here. Without making an assessment of how it sounds. Apparently many here don't care too much about that.
