[Elecraft] OT: Wireless Headphone

[Matt Zilmer]

If someone tries the Avantree (thanks, Al!) headset, please estimate or 
measure the latency for receive audio.  The spec sheet says nothing 
about an actual number, even though the banner adindicates Low Latency.  
Without an actual number, that is pretty worthless.  Most consumer 
electronics specs are similar, so no big surprise.

A few years ago, I surveyed the field for BT headsets. Because most 
headsets are designed for high-quality audio, their latency can be 
crazy-high.  There were only a few manufacturers that targeted 
communications (think hands-free phoneor HTheadsets), but their products 
were crazy-expensive>  It's likely thatthe usecases were government / 
law enforcement.

Thanks,
