My Input Re Bose and Telex and UFlyMike Bose adapter
I fly the a pair of the latest Bose, and I find them comfortable, but I wish they reduced a lot more high frequency noise. It seems that they really made little attempt at passive attenuation.
I also have the Bose Quiet Comfort II headphones with the UFlyMike adaptor, and it works very well, a little noisier, but these are my seven year old son's headset of choice.
I bought a pair of the Telex ANR 50D's, and sent them back before ever trying them in the plane because they had a pretty strong hiss when I turned the ANR. I was also disappointed in the cheap plasticky nature of their construction. I have considered giving them another try, maybe only some of them have that hiss.
I have done multiple-day flights with brand new Lightspeed 30G's (tryout loan from Aerotronics). They were a real disapointment. I liked the lightness, but they have kind of a Bose-like lack of high frequency attenuation, and much poorer fitting earcups that caused frequent leakage of low frequency noise with the corresponding beating of the ANR. Completely annoying and crappy headsets for my head.
My favorite headset so far was one I bought off of ebay for $235 under the brand Basler Aviation. They had really good ANR, not as good as the Bose with the lower frequencies, but the overall attenuation was much better than the Bose with the higher frequencies. I was warned by the seller to be sure not to put the battery in backwards, but did so one day anyway, and they have been dead ever since. If anyone knows what brand these are made under now, or how to get these fixed please let me know.
I think that maybe the ultimate noise reduction might be combining in ear pieces with the Bose going over them. In other use the bose microphone, but receive communications through the in ear pieces, and have the ANR benefit of the Bose with the high frequency attenuation of the in ear headsets.
I basically want the maximum noise reduction possible. I have very good hearing (I can hear ultrasonic motion detectors no problem) and I want to keep it that way.
