It’s not so much the bass in Howard’s voice, it’s everything between the bass and the treble that sounds like it has been reduced (mids). So it’s deep and clear but also very thin, where any little noise in the real world can be heard over it (more than normal on the AirPods). Because it’s thin you have to turn it up a bit, and then you hear more bass than you used to because it is louder, but the extra treble is what gets tiring to the ear.
By more bass, microphone thumps on Howard are much more prevalent now. You can hear every little adjustment people make to the mics.
That same megaphone bit is when I really had to take the AirPods out of my ears! The treble was really hitting my Hein.
I'm still on iOS 12.1.4 and I just checked that my AirPods were on firmware 3.7.2. I then listened to some music to memorize how they sound. About a minute into the music the AirPods stuttered and stopped and then resumed playing music mid-song, and it sounded different. When I checked it was on 6.3.2 now. I should have put my iPhone into airplane mode to prevent the update.
My problem is they won't stay that tight unless I hold them in place, so when I let go and they loosen their fit, then the sound becomes thinner sounding. With the firmware 3.7.2 this was not a problem, and due to my poor fit it prevented the mids from being too forward.
But now the midrange is definitely more sucked out sounding, and I have to push the EarPods harder against my ears for a tighter seal to get them to sound more like they used to. I use AirDots applied to my AirPods to make them stick in my ears better, but it's not a prefect fix.
They now sound more fatiguing and grainier with some compressed AAC and MP3 music. Brad Paisley "American Saturday Night" the song "Welcome to the Future" in 256 AAC is
absolutely unlistenable. No joke.
However, this isn't a consistent finding. Camilla Cabello album "Camila" in 256 AAC isn't nearly as fatiguing like Brad. With Dave Matthews and Tim Reynolds "Live at Radio City" in 256 AAC it's actually nicer sounding, where the ambience of the live audience is enhanced. I actually listened to dave's album for several songs as I enjoyed it so much.
When I listen to some lossless music, like Amanda Palmer "Performs the Popular Hits of Radiohead on Her Magical Ukulele", it becomes slightly less fatiguing sounding. And the air and ambience in lossless live recordings, such as Bill Evans "Waltz with Debbie", is noticeably improved.
Thanks Apple - now instead of being able to enjoy anything via Airpods, I have to pick and choose music that the tuning of the AirPods will complement each other.
I absolutely have to get a better fit somehow, as that makes them sound better. I have some silicone AirPod condoms that hook into the inside of my ears to try but I can't charge them with these on and they are a pain to install and remove each time. I also have some new over-the-ear hooks to try, before I give up.
What I like about AirPods is that they don't block sound, so I feel safe walking around with them in place, and can hear outside noises that I need to be aware of when I'm out in public (can't run or be active or they fly right out). I have several high end in-ear monitors with a BT cable that all seal out about 20-25 dB of outside noises, and so I feel like I'm walking around in a vacuum but can hear my footsteps via bone conduction. I don't feel like it's safe to walk around and run errands with those in my ears.
