I'm thinking of getting a pair of these RF wireless headphones for gaming. Latency is my primary concern and I haven't been able to find any solid information on how much latency these headphones have. In the course of my Google research I've read 30 ms, I've read 1 ms, and I've read essentially zero. They take (only) analog input which is certainly a good sign, but I don't know if a substantial delay could nonetheless be caused by some part of the process of getting that signal from the aux line to the headphone speakers. In particular, they use noise reduction, which I understand involves compressing and decompressing the audio before and after transmission. I don't know how that's done, but it seems like the kind of thing that would cause latency.

I don't touch Wireless/BT headsets but I understand what you need, 30 ms?? I don't think so, They use BT 4.0 which i guess you already know,So I'd say consider an alternative, If I were you I'd consider aptx , In this case you'd add $15 more and get the best rounded BT headphones which are the Mee Audio air-fi matrix 2. Although I am not sure about the latency of both, Don't want to get you in trouble just trying to help

 But I know most of them range from 30 (aptx) -150 ms, And tbh I don't think you can get lower unless you go Sennheiser.

30 ms would be far too much latency. It's nearly 2 frames in a game that runs at 60 Hz. Really anything on or above the order of ms is going to be unacceptable. Even if I can't detect a 10 ms lag, my reaction is nonetheless going to be 10 ms slower, which will cause it to be 1 frame later more than half the time, which of course can make a huge difference in many games.
 
Actually these headphones don't use bluetooth. Here's a link to them on Amazon. They use RF. Analog. Which, based on my limited understanding, should have latency much less than 1 ms at reasonable distances. But the transmitter and the headphones are both basically black boxes to me, and I have no idea what is done in terms of processing the signal before and after transmission, or how long that processing takes. Hence my uncertainty as to the latency.
 
However, I did buy a pair just because I happened to find them at an excellent price, and my amateur ears cannot detect any sound lag, so that's at least not a bad sign.
