OT: Wireless Headphone

Al Scanandoah
Looking through the archive, I didn’t find much info about what units people are using.  I did, however, notice several caveats about the latency of Bluetooth headphones, especially for CW.

It looks like there are now several BT headphones on the market that claim to have low latency, which may or may not be suitable for amateur radio use. Of course, an external BT transmitter would have to be plugged into the rig’s headphone jack.

One item that looks promising is the Avantree unit:

Has anyone tried this or something similar?

I'm no expert, but getting Bluetooth wireless phones and.or buds to work
with sufficiently low latency is (based on my limited
experience/research) dependent upon BOTH the BT version/capability
(hardware AND software) in BOTH the phones/buds AND the BT
receiver/transmitter in your device (laptop/desktop, et al).

I DO know that even my very nice and up to date Jaybird earbuds which
are awesome for music, et al.  do not work with sufficiently low latency
on my Dell E6540 Laptop with the Intel Wireless AC and Bluetooth card I
am using.... I suspect it is a problem with the BT implementation used
by the slightly long in the tooth Intel BT card...

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,

OK, I did some digging and found marketing info from Avantree.  When they say “no” latency, they mean “some” - on the order of 40 msec when used with a transmitter that supports low-latency aptx codec mode.  This sounds reminiscent of a Monty Python sketch.

40 msec is about one dit at 30 wpm, which would probably throw me off. I’ve tried to listen to my own sending via various SDRs, and it’s agonizing.

Time to delve into analog solutions.

I have tried several.  I have not found any that work for me on CW.  Rcv is
not an issue, but sending is very difficult.

Re: OT: Wireless Headphone

bill steffey
get one of those cheap FM bdcst band wireless sets ...

THEY ARE ANALOG...  REMEMBER THAT STUFF ,.,,,,
NO DSP  NO LATENCY....

HARBOR FREIGHT FOR 10$ us....

IF YOU DON'T LIKEIT , GUT IT AND USE THE RADIO ON A SENNHEISER.

I previously used a second receiver & BLU TOOTH to simul monitor the
local fm repeater for an 'elmer' net,,,,   when it was my turn to
talk, I thought I was in Wrigley field...and I LOST THE ABILITY TO
SPEAK  COHERENTLY.
(  like I ever could ....)
