I have an admitted headphone fetish.
I did end up selling the very good B&W PX headphones; they were good from an audio quality perspective, but just too heavy for their primary use, long-haul flights.
I decided to stick with the slightly dated Bose QC35’s; while the Sony WH-1000XM3’s seem to be the new king of the hill, the difference doesn’t seem to justify the price tag.
But I did end up buying a pair of Beyerdynamic Aventho (wireless). While the software app is a bit buggy, the audio quality out of these headphones is simply sublime. I really enjoyed the sound out of the T51i’s that I have, and the Aventho’s don’t disappoint.
They’re definitely a good pair of cans!
