IMO, putting NC on bluetooth phones is a downer. I think it is fair to say, the price of NC is a decrease in SQ.. IMO again, bluetooth headphones can't afford to give away any SQ.. Sheesh, they are shunned on here in Head Fi, simply because of their lower SQ then wired.. But, they are getting better.. IMO, to include NC which cost, why didn't they leave it out..and make a model with just NC? That is what Sony did.. On my beloved Sony MDR 1RBTMK2, they have and MDR 1RNC, a plain MDR 1R.. That's 3 models of the same headphone.. I was really ready to jump on that $149.99 for refurbished one..
Anyway, I got 3 sets of headphones traveling by air all to me.. My replacement MK2s, my replacement HK BTs, and the AF62.. All of them according to tracking are in the air..
BTW, on my learning curve, I am finding out that the open headphones are for home use or in a closed environment.. I want to get a set of open cans, but can decide on which ones..
These will be strictly for home use, and my closed back phones are for mobile use out in the open, and work.
