• FWIW, I get a lot of use out of my AKG N60NC bluetooth. They fill their own little niche by being the only foldable, on-ear, noice cancelling bluetooth headphone and it was exactly the combination I was after. No doubt the market leading Bose and Sony over-ears are better, but personally I get tons more use out of something I can stuff in my pocket.
    These are yesteryear's technology, as far as I can tell there have been no updates or improvements since 2017. But at the same time they cost less than half of the Sony/Bose and I think their sound and NC capability makes them worth exactly that. The NC is effective, but crude. It basically only takes out consistent humming noise, but then again it does so very well. This makes them great on planes and trains or when working with machinery. In my experience the NC makes little difference when it comes to human voices. The benefit is that the plane captain's tannoy announcements comes trough clearly enough, but the downside is that it won't protect you from your inane co-workers of failing marriage. Sound quality is in a sense faultless as I reckon no part of the register is particularly suffering, and there is no noticeable muddle. But at the same time it seems that BT is just too much of a bottle neck for the sound to be considered in any way good. It's OK, nothing more.
    Physical execution is pretty good. Feels solid and is easy to fit on your head.

    Tl;dr
    Costs half as much as the Sony and Bose over-ear models, which makes them decent value. A very worthwhile investment if you travel by plane more than a couple of times a year. If not, keep looking.
