Lowest price seen for this kind of headphone which is for a specific kind of person. Had a listen to these in Singapore which were pretty decent. It won't replace your audiophile gear but it does come with adequate noise cancellation on the go. Apparently 200 hrs burn in according to a YouTuber audiophile review.
Price performance wise, there are also Px7 s2 which are a better bang for buck, at about half the price of Px8 RRP but not that much of a sale at Qantas marketplace. For most people, the Sony 1000XM5 will do fine audio wise and have better ANC and deals. Otherwise, at the top of the mountain, Focal Bathys is another option comparable to PX8 for a different kind of sound, although those haven't been seen on sale brand new.
Sometimes our hunger for a deal drives our body forward, and when looking back momentarily, we see collections of who we've become.
Great post for a superb product. Audiophiles rejoice!
