John,I have the Sony WH 1000X M2. They are the most comfortable cans ever for me. Noise cancellation is excellent esp as regards the KPA 1500. I hear better with them and do so in comfort. Never had the least bit of RF trbl from 160 to 6.73 Doug EI2CN Age 77 like a kid againSent from my Galaxy -------- Original message --------From: John Reilly <reill...@comcast.net> Date: 19/11/2021 01:16 (GMT+00:00) To: elecraft@mailman.qth.net Subject: [Elecraft] Headphones (Again!) I recently purchased a Bose QC-45. I used it for about 5 minutes in a CWops contest, and got RF in the left headphone. I disconnected it, and returned to my Bose QC-35's. The QC-45's have been returned to Amazon.I had a similar problem earlier in the year with the Bose 700 headphones. I tried various toroids, but never could isolate them from RF (particularly a problem on 40m). Obviously, this is is not something Bose is concerned with. Fortunately, the QC-35 gamer headphones work well. With all three headphones, I used the headphone cable (not Bluetooth -> delay problem). FWIW, I like the Bose noise cancelling because it does a good job attenuating KPA1500 fan noise.Has anyone used the Sony WH-1000XM3 headphones? How do they work in an RF environment? - 73, John, N0TA______________________________________________________________Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:elecr...@mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.htmlMessage delivered to turnb...@net1.ie ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net
