While there is no way of knowing, I haven't even seen the Apple rumor mongers spread rumors about the next AirPods Max yet). Am I spreading anti-rumors? ?
The fact is I love my AirPods Max, even after the honeymoon period! I own several BT and wired headphones (using wired with desktop headphone amplifiers/DACs). So I think it is fair to say I am not so easily impressed (given that BlueTooth headphones right now can't truly top a decent wired rig). But Apple, I'm impressed with the AirPods Max!
My philosophy is why deprive yourself of a great headphone while waiting for version #2. Listening to music, and using them for movies has been a great listening experience.
I truly hope the AirPods Max do not go the way of the HomePod, or Apple decides to turn it into just another Beats style brand. Sorry Beats lovers.
In the meantime life is short, if you can spend the money I'd say go for the AirPods Max. Maybe in the end it will be a "one of its kind". I truly hope not. But in the meantime using the AirPods Max is well worth it if you are looking for a premium over the ears, BlueTooth headphone!
