Unfortunately, my current headphones is the last pair and they are probably going to die randomly any day. I have literally no idea how "in the know" people find good headphones these days, especially if you don't want earmuff headphones or apple earpod knock-offs. It looks like all companies are only making one of those instead of normal ones.
The amazon listing was 1984'd so you can only find it on ??? websites.
Note: this is mostly just a rant.
Most of the entry-level wireless Sennheisers are good, but then they tend to have lighter bass than most in exchange for better clarity and an equalised sound. There's a reason their high-end models are reference headphones.
The CX or the 250BTs are fine, I use a 250bt as my "I don't care if it gets trashed" headphone. You should be able to find these on sale for $40 USD if you look around. I think they have a level below this too.
Thanks much!
