Apple Releases New Firmware for AirPods Max With Lossless Audio Support (2025)

This new build was published in the original URLs that macOS and iOS were failing to access, so these updates are no longer gated based on OS version (macOS 15.4, iOS 18.4).

Quickest way to “force” an update check:

1. ⁠Make sure you’re not wearing them and they’re charging out of their case (no need for 2s/30s listening sessions)
2. ⁠Go to Bluetooth settings
3. ⁠Click Disconnect (on Mac), or the More info (i) button and scroll to the bottom & click Disconnect (on iPhone)
4. ⁠Click Connect (on Mac), or tap on their name (on iPhone) once disconnected.

It immediately triggers an update check.

Seems like the whole OS-specific update channel strategy backfired.

So, here’s my thought on Bluetooth vs USBC listening. 1st of I have ASD & ADHD and part of my particular flavour of neuro spicy comes with auditory processing disorder and mild synaesthesia, which lets me hear down to 2Hz (tested by audiologist) and “see” the music as a sort of cross between a lava lamp and iTunes visualiser but this doesn’t affect my vision at all because it doesn’t use my eyes so it’s not really seeing it per se. Anyhoo, ADHD ramble over and to the point… for my particular ears and brain,
Atmos tracks, usb sounds marginally better via USB than Bluetooth
AAC sound exactly the same on both
Lossless sounds fuller on USB, (and the magic brain pictures are clearer and bigger even if I can’t hear much difference because I’m male, getting older and top hearing range is down to just below 16KHz, used to be much higher when I was younger, remember spicy brain)
High res lossless, night and day difference, soundstage has room to breathe and is just bigger and fuller on usb. Was listening to take five and the sub base (which in this track was a greenish wiggly line blob) moved from behind my neck on Bluetooth to below my shoulder blades (told you, spicy brain pictures, it’s weird)

Admittedly the AirPods Max still don’t hold a candle to the performance I get on my Mac hooked up to a proper DAC and headphone amp with balanced output to either my HiFiMan HE4xx or Beyerdynamic DT770 PRO 250ohm, but for out and about, Gym, commute, listening in bed etc where I can’t lug all that gear, or be bothered with wired, I prefer my AirPods max and Pro2 to any other wireless headphones I’ve tried and I’m glad the Mrs gave me the Max last Xmas. Ok I’m going to take the last of today’s adhd meds and go to bed now

I tried it a little bit ago and just my initial impressions is that it didn’t sound ‘different’…it sounded fuller or richer? For example, I was listening to prime mover from Rush…in the break section, you can hear the echo of the vocals without issue. When I connected the cable to the headphones and iPhone, you definitely hear it even more pronounced. It wasn’t like new worlds opening up, but more like you don’t have to focus so hard to listen for the details, they are more pronounced you could say.

I’m used to having simple earbuds and the AirPods Max are probably the nicest headphones I’ve listened to aside from a pair of STAX electrostatic headphones…but those were an entirely different league. Literally felt like I was sitting next to Jimi Hendrix while he played live about 3 ft away.

The science behind speakers and earphones is quite amazing. I think the Max sound great but...far from high end speakers which can reproduce some really amazing sound when the source is well engineered and lossless or near lossless. If someone wants that "open stage" feeling, they should get some good open back earphones. It is quite a different experience than what most of us are used to with closed back headphones. I say this as someone who grew up with the middle higher line of Sennheiser offerings. Presently, I am listening to some speakers that use folded ribbon tweeters. They have a sound a bit different than the usual cone speakers. Headphones, like the STAX you mention are atypical to the design most of us expect from headphones. All great science and we get the benefit of it all.
