^I feel similarly about my HD58X. I have a friend who owns an Aeolus..his second “open-back” headphone mind you. He started out with a Nighthawk. Anyway I have been visiting him quite frequently since the ZMF turned up
At first it seemed like everything I would ever want out of a headphone, but I am fairly certain my mind played tricks on me. Firstly, the Aeolus looks the part...like many other pricier cans. It looks like a true TOTL contender..and it’s got the bass to go with it unlike most other dynamic driver headphones..but that’s the thing: it reminded me rather a lot of my HD58X in it’s tuning that I just had to bring my Sennie with me the next time I popped by...and wouldn’t you know it - I ended up prefering the cheap plastic coconut. Whilst losing out on bass extension, it still came out on top with regards to midrange and treble clarity. Also surprisingly the more detailed of the two, at least to these ears. Most importantly though the Sennie is an open-back headphone, whereas the ZMF is not, ultimately making it sound that more natural to me.
Long story short: I think we spend way too much money on unnecessary (but in some cases quite beautiful) bling and sadly it often overshadows the real magic. The music.
