Open Back: HD 6XX

Closed Back: K371

IEM: ER2XR

TWS: N400

Desktop DAC/Amp: JDS Labs Element(1st gen)

Portable DAC/Amp: Creative SXFI

Overall satisfaction: Honestly lost a lot of interest in other IEMs. Etymotics just win the comfort compared to the typical like 5.5mm nozzle IEMs. HD 6XX are good enough. K371 aren't my favorite(comfort could be a lot better if they had deeper earpads), but no pressing urge to replace.

AKG N400 is I think the item I'm the least happy with, despite using them a bit. Sound is solid, but passive isolation is terrible, ANC is a bit wonky, short term comfort is fine, but long term comfort is lacking, and I wish I wish I wish that there was a swipe-back command option to turn ANC on/off on the left earbud, since there is a swipe-forward you can use for talkthru/ambient mode toggle.

JDS Labs Element honestly has given me zero issues, looks great, don't see a reason to replace for a long time. Creative SXFI dongle doesn't seem the most power efficient, as it gets a bit warm in use, and phone battery drain gets a little high. Wouldn't MIND replacing it, but until it breaks or gets lost, not going to spend money on something else.
