I went over to Yodobashi Camera, the giant electronics store in Akihabara this afternoon, to try to compare speakers. They have a large Apple corner there. It was noisier there of course, so it wasn't a perfect comparison.
Anyway, I tested on the same model. I didn't have Netflix access there, and of course my music wasn't on their floor model, so I tested with YouTube songs. I played these two:
Forever Young (Joan Baez) -
Both Sides Now (Joni Mitchell) -
They sounded pretty beautiful!
NOTE: The moderator of these forums edited by post and removed the two YouTube links.
It was an unfair comparison of course, because I hadn't done the same test at home. So when I got home I created the same conditions: playing the same songs in Safari. And... they sounded beautiful at home too!
However, using the Boom 3D equalizer app with Vocals setting it sounded more beautiful. So I will probably purchase it. It's under $15 right now with some sort of flash sale. And Siri sounds nicer too. And with Movies setting Netflix movies also sound better.
Anyway, that's apparently just the way they are. And the issue with me might be, as some have suggested, a loss of high frequency hearing with age coupled with the increased bass of the new speakers. That might be why I was left with the impression that the vocals were less clear than on my iPad Pro, which doesn't have the spatial audio and bass of the new MBP.
Side-notes:
I wonder why Boom 3D is so inexpensive compared with the supposedly older and less featured Boom 2, which sells with a subscription model. Boom 3D is currently under $15 right now.
I also tested the free eqMac equalizer app. It's also nice, but when it's on and I use FaceTime the sound cuts out. The developer is looking at it on Discord. That app also have a Pro version that is subscription based, and is actually more expensive than Boom 3D. Boom 3D works fine with FaceTime, and a little indicator in the panel indicates that FaceTime is running. It seems more seamless than eqMac, just sitting there quietly in the menu bar.
Anyway, I guess I'll lay this issue to rest for now, and look for something else to gripe about. :)
