[Elecraft] K4 Headphones Q

[Jim McDonald]

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.

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.

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.

How about latency for CW either wired or wireless?

How do you deal with battery life in contesting?

Stay safe!
