That would be my first higher end headphone, the Beyerdynamic DT880 Edition 250 ohm. I discovered so much detail in my music, it made me speechless back then.

Abyss Diana V2 in my case. My first high end headphone and one that I really enjoy using. The other one is a Grado Sr 125 I bought 20 years ago in Houston by mistake when I knew nothing about headphones. I do not use it that much but is a special headphone for me because it started the hobby.

Where do I start? A promise broken too often but I can’t part with my HD800S…although I did many times only to buy it again and again.

Hifiman HE-500

 

[dunring]

I'm keeping the Hifiman He5xx since it's so comfortable and don't need to equalize it. Also not so expensive to use every day since I test a few amplifiers a week that come in and not a huge risk since I got these for $80 on eBay. Also the 7hz Zero:2 IEMs are a keeper for travel and not worrying about breaking or losing a $24 pair. I've had the Hifiman Arya Stealth a few times, and would consider them my endgame pair. I have a business and can't tie up too much by keeping a really expensive set.

It'd be my Quad Era-1 for sure.

Not my first "audiophile" headphone, but the most enjoyable bc it works wonderfully with all genres I listen to.

HE-500, HE-6 SE, HD-600 - I already got rid of the rest, they stay.

For vote counting: HE-500

Beyerdynamic T1 Gen 3, which is the only headphone that has stayed my main headphone longer than a year, in fact it's been my main for over 3 years now. Also my modified Beyerdynamic DT 480, spent years tweaking this thing and it sounds incredible.

This is close to being my favourite headphone but is definitely one that I keep / never sell!!

[A classic / in pristine condition / dressed impeccably / sounds even better!!]

The Abyss Diana V2 for me.

 

[dougms3]

Focal Clear OG.

Never say never, I thought I would never sell my Pioneer SE Monitor 5 but its gone.

The Creative Aurvana Live! was the first "good" headphone I tried that fit my personal tastes. There are plenty of headphones with better resolution and other technical aspects, but the CAL! helped me define what I like and dislike in headphones more than any other. I've had to repair mine many times, but it is still kicking, and every time I put it on, I enjoy that warm, immersive sound that sent me on my journey through many different sets. These days, I'm firmly entrenched in the Foster/Fostex/Denon sound signature with my closed back headphones. Still need to find an open back that can take me a step or two above my Philips X2.

ill take my HD800S to my grave.

 

[Skeith]

I'll never sell my HD800S. Their magical soundstage makes me hallucinate.

 

[Markolav]

Most likely my Denon D2000. Maybe it's just nostalgia but that pair still has some kind of "magic" on it. Such a versatile and musical headphone.
