This question already has an answer here:
I have gone to an electronics store and have tried on Bose and Beats headphones, both of them have a pretty annoying sound delay which is insanely apparent and anyone who says it’s imperceptible must be deaf.
While listening to music it doesn’t matter and for videos it wouldn’t be that bad, for phone calls especially slower or international VOIP which already have the delay, it is absolutely horrible.
I noticed that the more expensive the receiver - the lesser is the sound delay, I also noticed that it is some sort of low power garbage which causes that delay to happen.
Example: streaming Bluetooth music to my PC one time is super snappy almost perfectly in sync without any perceived delay, some other time there’s like a half a second delay (distance would be irrelevant) although I am tempted to try to force high power by moving too far from the receiver, and then seeing if that has forced high power low latency
Example 2: I have these cheap $25 bluetooth earphones for running, they have a really bad half a second delay.
Considering radio waves travel with the speed of light, I am very tempted to deposit a log of blame on the “low power” protocols and inability to force high power low latency protocols for this issue.
Low power protocol is fine for synchronizing irrelevant garbage to/from your watch, music, file transfers, I strongly disagree how it is being used for media and calls.
That said, I wonder how is the delay on AirPods in comparison to latest (2k17/18) Bose. Bose delay isn’t that bad, but still would add an annoying delay for phone calls.
