So I'm back at my other place and long story short, my OG HP's are working flawlessly.
- Full-strength signal to my Unifi WiFi 6 AP, with no connectivity issues unlike before.
- AirPlay works perfectly. I would struggle to stream from my MBP M1, iPhone works great, as does the iPad.
- Apple TV connects with no issues (and also seamlessly while I AirPlay from my MBP). I've not tried the voice enhancement yet, but I'll give it a go later.
- No stereo pairing issues.
- No lag. Really, this part is quite impressive. There would always be a 1-3 second delay when making a change such as playing, pausing, skipping, etc....from another device. There is about a 0.5 sec delay now. It's noticeably much faster.
This is what the HP OG's should have been from the start.
Well done Apple. Just don't break it in 17.2!!!!
