  1. Bose QC35ii & nflightmic microphone assy arrived today. Assembled easily, certainly smaller & lighter than the Bose A20. I’ll take some side by side pics & take them flying in the next few days & post my thoughts.
  2. Misunderstood you. Mine has only a single control.
  3. That's a good idea, I'll have a look at the CONFIG setup & take a photo. I've taken photos of what I thought were important, like the TX, never thought of the radio....Peter
  4. I have to admit to not knowing. It's a dual G3X with a GTR 200 radio, no separate intercom panel. I'll look next time I'm at the aircraft......Peter
  5. I've had a series of replies from Nflight about their attachable Mic setup. They seem to favour the Bose 35 11 over the Bose 700 as the older model (the 35) is less bulky & has very similar ANR in a flying environment. The Sony 1000 xm4 requires an adaptor, which they sell, but it adds to the overall bulk of the headset. They confirmed a comment that RFguy mentioned about adaptors that may not be wired correctly. Another factor that hadn't been raised in this chat was the impact that auto squelch might have on different brands of headsets connected to th
  6. I even recognise them. I only went as far as the 3M website. There were a lot of different industries listed, aviation wasn't included.
  7. I remembered the name from years ago too. I looked them up, now a division of the 3M Company. They make headsets & noise protection gear for all sorts of industries, but not aviation anymore apparently.
  8. RFguy, your project in the US explains your knowledge level on this subject. I'm hoping to have a reply from nflight tomorrow, I'll post their response.
  9. RFGuy, a bit more info that I've found. The Bose QC 35 11 has been replaced by the Bose 700. Load impedances are; Bose 700 60 ohm ANR OFF, 455 ohm ANR ON BOSE QC35 55 ohm ANR OFF, 465 ohm ANR ON SONY xm4 16 ohm ANR OFF, 47 ohm ANR ON. The Sony figures make sense when I reread your comments about modern chips driving low load impedance. I'll be interested to hear your take on these numbers, also any reply I get from nflight & to hear further from SplitS about his views on ANR, Bose vs Sony vs anyone else. P
  10. RFguy, You've raised some interesting points. You'd assume that an outfit like nflight would have thought all these issues thru & perhaps they have. To be sure, I've emailed nflight a list of questions, based on the issues you raised in your post. I'll post their response when I get one.
  11. SplitS, I picked up on the different size plugs, 2.5 & 3.5, & saw that nflight sells an adaptor. Thinking about this overnight, if I went with the Bose QC 35 11, that sort of contradicts the line of your original advice, that there are better solutions in the ANR world the Bose. Now I've just read RFguy's further post which addresses one of my original questions about impedance mismatch. RFguy, my coms setup is via a 5 year old Garmin G3X touch panel, so I assume it would fit your definition of a new intercom. I also assume that the nflight NC mic is up to the j
  12. kgwilson, tonight's a night of surprise. First was SplitS post about the nflight, now you tell me Bose is Apple. Certainly explains the pricing. I've been an Apple user for 35 years, in earlier days, it was outstanding gear but expensive. These days it's just expensive. But like many things in life, once you're into a system & have an investment in dollars & a huge investment in learning time, changing horses is very daunting.
  13. SplitS, you've opened up a new world of possibilities to me. I've often wondered at the price difference of the A20 type to Bose passenger ANR prices. The WH-1000XM3 has been replaced by the WH-1000XM4. Very similar, just upgraded from what I've read. Available for $430AUD. The nflight mic kit is around $560AUD delivered here (including a Sony adaptor). Still expensive but around $700 cheaper than the A20 with hopefully better performance. The headset, mike & adaptor is $990 AUD plus some local delivery fee. Another option is to buy the Bose QC35 11, if bought f
  14. Thanks, yet another thing to look out for! Now you've mentioned it I have heard of headset incompatibilities, never struck it myself, but I'm certainly alert to the possibility....Thanks
  15. Hi, was there some sort of impedance mismatch? Do I understand correctly, that you could talk to the outside world OK, but not between other headset users?
