Re: [Elecraft] K4 Headphones Q
I did an initial test of this headset yesterday and found that the audio quality was good, but there was some background hiss. It could have been because the headset was not properly powered, since I have it plugged in to my mixer with phantom to 2.5v jerry rigged. I have a proper adapter coming tomorrow, and will do some proper analytics and comparison to other mics.

Re: [Elecraft] K4 Headphones Q
Just did an OTA test and Fan Speed 2 was inaudible but Fan speed 3 could be easily heard. But since I've never seen Fan 3 in an SSB environment that I can remember I think this will do. Obviously other shack noise similar to FS3 would also be an issue but that never happens here. M/M environments may not work. I'll run a test later with my ModMic to see how that fares vs fan speed setting for comparison. 73 jim ab3cv On Sun, Oct 18, 2020 at 10:42 AM Jim Miller wrote: > > https://www.amazon.com/gp/product/B07W3W9LHV/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8=1 > > jim ab3cv > > On Sun, Oct 18, 2020 at 10:39 AM Rich NE1EE <73.de.ne...@gmail.com> wrote: > >> On 2020-10-18 10:10:-0400, Jim Miller wrote: >> >I took a chance on the QC-35 while on sale and so far I'm pleased.

Re: [Elecraft] K4 Headphones Q
I just received the cable I ordered from Amazon to replace the one that came with the Bose QC-35 II headphones. Made in China, not surprisingly, but has a 5', flexible, braided cover and comes with a screw-on 1/4" adaptor for the front panel headphone jack. It came just in time before my cat ate through the very thin, OEM cable. https://www.amazon.com/gp/product/B088CNY2VV/ref=ppx_od_dt_b_asin_title_s01?ie=UTF8=1 Unlike my ancient Bose QC2 headphones, they work without turning them on, saving the rechargeable battery, when noise cancelling (or Bluetooth) isn't required. They work great with my cell phone using Bluetooth too. 73, Jim N7US -Original Message- The rechargeable battery with noise cancelling on and Bluetooth off is rated at 40 hours. It uses the same USB charging plug as my Logitech keyboard, so I have a charging cable on my desk. I connect to my K3S with the cable, which is inadequate. It's 4' long, lightweight, and flimsy. The jack on the headphones is a sub-mini, 2.5mm, and the other end is a mini-phone plug, 3.5mm. Amazon has several replacement cables that are heavier and designed for these headphones. 73, Jim N7US -Original Message- How about latency for CW either wired or wireless? How do you deal with battery life in contesting? Stay safe!

Re: [Elecraft] K4 Headphones Q
I have one of these aftermarket boom mics for my QC25. It works fine. Just be careful of the wiring of the L and R channels because the adapter splitters sometimes switch them.

Re: [Elecraft] K4 Headphones Q
Hi Rich, I wanted a similar result, that is noise canceling headphones combined with a headset mic. After many trials, I came to the following solution: Bose QC35 headphones on wired connection Shure MX153B/O-TQG headset They both are corded. The Shure fits over the ear and under the QC35 so that it is barely noticeable. I highly recommend this solution as providing both excellent noise cancellation and superb audio quality.

Re: [Elecraft] K4 Headphones Q
Analog radios have almost no latency, but it's almost impossible to find a pure analog radio anymore. Most conventional radios switch over to DSP in the IF stage, which introduces anywhere from a few ms of latency up. For example, the TS-890s hybrid has about 25ms receive latency. Then when you go to full SDR you probably get a somewhat bigger number, anywhere from 40 up. But the real source of latency in current systems is Bluetooth, which can run in the range of 200ms. New Bluetooth protocols aim to bring that down to a reasonable 40ms, but they aren't widely available yet. So for now, use wired headphones.

Re: [Elecraft] K4 Headphones Q
There are newer headsets claiming 40ms latency, but the host must support the LL format. My estimate for the QC-35 which uses the ATX format is in the range of 150-250ms. This may not be a problem at slower CW speeds for some folks, but I couldn't tolerate it. ED / W2RF -Original Message- From: Rajiv Dewan Sent: Wednesday, October 14, 2020 11:45 AM To: E.H.

Re: [Elecraft] K4 Headphones Q
Sorry, but I need to correct a typo.

The jack on the headphones is a sub-mini, 2.5mm, and the other end is a mini-phone plug, 2.5mm.

I use a bluetooth set from Avantree and there is no latency that I can detect. I operate CW almost exclusively, using a key paddle and copying in my head.

Re: [Elecraft] K4 Headphones Q
They are over ear, which helps make the noise cancelling extremely effective, and also the headset is not tiring for long periods of use in contests, for instance.
