Any idea what the latency might be on these and other Apple ANC earbuds for that matter? I would buy them to use with my PC's Avantree DG80 transmitter and YouTube TV in a web browser. The DG80 supports aptX and apt Low Latency. Most headphones that don't support those codecs or aptX Adaptive give 200+ msec latency, which is unusable. I don't expect Apple to support aptX, but my Sony WH-1000XM4 over-ear headphones don't support aptX either, and somehow they're delivering sub 100 msec latency, which I can live with.
It's a real challenge finding earbuds that have effective ANC, are sufficiently low latency, and don't suffer from comfort issues, high-pitched hissing, range limitations, poor audio quality, etc. I've tried a half dozen from Bose QuietComfort on through lesser brands, and the best ones I've found are EarFun Air Pro 2. Sadly, they are standard (high) latency and lack the gaming mode of their "Free Pro" brothers, but they're otherwise so good, I'm keeping them for use with my iPhone 13 Pro in the gym. iPhone video apps generally compensate for BT latency so don't pose the problem PC web browsers pose.
tl;dr : They're great in every way except resuming paused audio with my Avantree DG80 transmitter, which is a dealbreaker. If anyone is using their Beats Fit Pro with non-Apple devices and has a problem resuming audio after a few minutes of pausing, please reply. ETA: I replaced the Avantree DG80 with an Asus BT500 Bluetooth adapter, and it solved the "resume paused audio" problem. The latency remains good, but the range is worse with this transmitter. It's worse than other Bluetooth headphones and earbuds I have. Also, all my other devices show battery level in Windows Bluetooth settings, but the Beats Fit Pro does not.
After trying my 2nd gen AirPods with the DG80, finding they provide sub 100 msec latency, and verifying the Beats use the same H1 chip, I went ahead and bought a pair of the Fit Pro to try out. Great success! Latency is 80 msec per this test file played in a web browser on my PC, which does nothing to compensate for latency:
This is on par with my Sony WH-1000XM4 over-ears, and the Fit Pro will provide a nice alternative. To get the best sound and noise cancelling, I had to move up to the large tips. The software said I had a good fit with the mediums, but the large provide a substantial improvement. The midrange no longer sounds biting, and the ANC knocks out my central air much better. I find them very acceptable for music. They fit my ears comfortably and securely, and they go in and out of the case easily.
One thing I notice with the Fit Pro is that I'm hearing mouse and keyboard clicks, which I don't hear with my Sony. That's not a function of the ANC, though. It's just the difference in passive isolation between the Sony over-ears and the buds.
On the downside, while writing this message, I paused the music I was playing, and when I resumed it a few minutes later, I had no sound. The buds were still connected, because the volume control still worked (there's a visual display on the PC), but I couldn't get them to play. I re-paired them with my iPhone and verified it doesn't have this problem. I turned off in-ear detection before forgetting them from my iPhone and re-pairing to the DG80. Maybe that'll help. If not, they'll have to go back.
Well, they're going back. After pausing my music for about 7 minutes, when I resumed there was no audio, but I did hear some very faint electrical noise in the background. A few seconds later, the music resumed, but the connection was cutting out. After restoring normal connection, I tried it a third time, and I got no audio at all, just like the first time.
Dammit, I was really liking these, but they're just not gonna work. This is a unique problem. As I said, I've tried earbuds from Bose, 1More, Razer, EarFun, TronSmart, and one more I can't think of, and none of them did what the Beats are doing. I still have the 1More ColorBuds 2, and they definitely don't do this. Apparently the Beats have some kind of sleep mode, and they don't come out of it successfully with my DG80 transmitter.
