Not sure if I count as an audiophile but here’s my list o’ stuff I’ve acquired over the years and like the best:

My house had speakers built into the ceiling when I moved in so I have a Denon AVR-S760H amp and play audio through the surround sound with an AppleTV, record player, or whatever other source. (I forget the record player model but it’s just one of the mid-tier Sony ones.) I also have some Sennheiser HD 598 headphones that I love the sound on. They’re open back so not appropriate for travel but if I’m alone and not in the living room, that’s my go-to.

I really like Sennheisers and I eventually splurged on a pair of 4.50 SE over the ear ones for travel. They have noise cancellation and a closed back so they work great on flights or trains. I like them a lot.

I also have some Beats Fit Pros that I use a lot. Most earbuds don’t stay in my ears very well so the little nubbin hook on the Beats Fits is really what prompted that decision but the audio quality ended up being perfectly fine for the form factor. Sometimes, you’re exercising or just listening to a podcast or a work call. They ended up being a good purchase.
