Wow, lot of nice stuffs there.
I'm curious how much you pay the Tenore and were you find them?
Zero Audio Carbo Tenore ZH-DH200 CT (Amazon) $44.00
TIN Audio T2 (AliExpress) $33.23
LKER i8 (AliExpress) $ $38.54
KZ ED9 (Amazon) $13.79
ED9 loser of the bunch
Can't go wrong with the other 3
Carbo Tenore for ultimate portability (bass a little lacking but they are so small)
T2 and i8 for sound (about the same)
I ran some sound fit tests because I was Having problems with all these staying in my ear so I tried either complys, spin fits or spiral dots in no amp, with the A5 and with the portable tube.
For the T2 I found the Spiral Dot and Spin Fit sounde and fit better with no amp and the with the fiio, with the tube the complys sounded better though but fit was bad as they tend to slide out or time.
For the Biggies I found that the spiral fits where better with both amps but the comply sounded better without. Plus they don't seem to fall out with the complys like the T2 does. Same for the LKER i8s.
For the Carbo Tenores the medium stock tips held and sounded best
All four buds came alive with amp support and nothing cold help the ED9 ($13.79) even changing filters and tips. Reminded me of the Soundmagic E80s.which cost $49.95
To me its a wash between the TIN T2, LKER i8 and Monk Biggies although none can stnad up to the Monk Zens but those are like 3-5 times the cost of these IEMs. They do show me how the harshness of all my KZ IEMs.
Still need to receive the Yersen ZEN 2000, TY hi-2 150ohm and FAAEAL 64 ohms. I received the DZAT DF-10 yesterday with the LKER i8 and KZ ED9 but haven't opened the box.
The question i how my Mass Drop Nu Force EDC and EDC3s will hold up at $59.99 and $99.99 they are way more expensive than this group of IEM/buds
