More than 30ms of delay is noticable. My old screen + mouse had a delay of ~50 crudely tested. My old bluetooth headset was over 400ms!
I totally believe you that delay is noticable. I haven't used iPhone, but Android has terrible UI lag virtually everywhere (pointless animations don't help, pro tip you can turn these off in developer options)
I bought the HyperX CloudX Flight (what a name) wireless gaming headset about three months ago, and I was shocked at how much latency I could feel in something that was supposed to be a dedicated gaming headset.
There's no inherent reason that a wireless headset has to have more latency than a wired headset, analog wireless being the extreme example of no added latency, but a purpose-built wireless headset seems like it would use some digital wireless protocol that is optimized for low latency, instead of buffering something like 100ms of audio in the channel. That ~100ms to ~150ms of latency really impacts reaction times.
So, I could switch to a wired headset... I just wish I could find a wireless headset that didn't suck. Microsoft just recently introduced their new "Xbox Wireless Headset", which looks awesome, but... the absence of any latency specification is not encouraging.
Gaming headsets are generally all low delay. HyperX stuff is all 50ms or less. The biggest thing is just don't use bluetooth which has terrible notorious delay.
Proprietary USB dongles for low delay headelsets is standard for foreseeable future.
Don't switch to wired, there's no point. Chances are, your HyperX headset has same latency as a wired connection.
How do you actually test screen and mouse delay? Is there some good software for testing each in isolation? I know of Is It Snappy? for iOS bu that only measures end-to-end latency.
Newer studies have shown recognition of events as fast as 13ms. https://news.mit.edu/2014/in-the-blink-of-an-eye-0116
