Office:
Philips SHP2000 → Panasonic RP-HC500 → 3M Peltor Optime III 
→ Superlux HD669 → Superlux HD662 Evo (but also Massdrop x Koss KSC75X when people GTFO and it gets properly quiet; oh, and also Jabra Elite 65t for when I need isolation but also really wanna listen to something but also I can’t take any more clamping from clampy over-ears).
Home/critical:
(Speakers only ->) Superlux HD668B → Beyerdynamic DT 880 Edition, 250-ohm → HiFiMan HE-400i → Verum 1 [Endgaem Acheevd]
Long trips with noisy transportation:
A few attempts with random earbuds/in-ear-buds, hated them → Panasonic RP-HC500 → Sennheiser HD 4.50 BTNC [Waiting for a reason]
Chilling outside, away from home:
A few attempts with random earbuds/in-ear-buds, hated them → Koss KSC75 → Koss KSC75 (2018), just because Massdrop reminded me how much I’d hate being without these if something happened, so I bought a new pair which turned out to sound different and better.
