Update:
Thank you everyone for your comments and opinions!

After cooling my head down a bit and using my APP2 and a pair of Beyer T90 that I still have, I concluded that I shouldn't get another set of over-ears at this time...I should have mentioned it, but since I wear glasses, using overheads during work is really uncomfortable, even with headphones as light as the T90. Anyhow, I'll hope to get a good near-field setup for work after moving to a new place in the new future :)

Very good point. I kinda feel like I picked up my AirPods (Gen 1 at the time) quite often even when I had the Sundara... Maybe I'm just very picky about comfort.

Good points, thanks. Especially the point about just using them for a few dozens hours before selling off is too familiar… that happened with lots of my audio gear (and cameras for that matter…). What I use most is what I end up keeping, so maybe I should just call it quits :P

Thanks—good advice. I’ve listend to the Aryas before and liked them. However, I’m mostly wondering whether or not I’ll actually use them enough to justify their cost… Might just sit this one out and reconsider in a couple of months.

Yeah it’s really about the convenience—but then you’re also surprised about how well they sound.

Yeah…I’m afraid not a lot of separation either? The S8 that I compared them to were just way better for that, but also too “sterile” at the same time. The SA6 had great punch and “grit”. Worked well for metal :)

Yeah they were pretty great while I had them.

Major take-aways: much smaller (including nozzle) than most of the competition—therefore great fit. Good bass for a full-BA set. Good resolution (but there are better). Very intimate—little "soundstage". Even though the bass-BA is "vented", these still wear like sealed IEM I feel (might be uncomfortable. YMMV)
I also drew a great color combo for them—blue/green. Many people get mostly orange ones, but those can look nice too.

lol yeah you’re right. Or maybe an Apple 3.5mm dongle. After the recent price hike here and the weak yen, it’s almost as expensive as the Arya…

Haha thanks :P
