Came into this thread to get some suggestions for what TWS iems to buy next, settled on the Nuratrues and the Fiil T1 Pro, the former because I was interested in the personalized tuning, and the latter because it was cheap at around $60.
The Technics sound interesting too, and so do the Grado GT220, but they're pretty pricey so may only get them much later on.
And to give back, I'm just sharing some experience that I have for TWZ recently.
I'm currently using the Sony WF 1000XM3 (most use as it has great sound, great connection stability and great ANC), the Jabra Elite 65t (got a refurbished set cheap, pretty decent sound, great connection stability, I rotate them with the Sony) and the Nuarl NT01A (best sound of the 3, but connection stability is spotty, hence limited use time).
I also had the Alpha Delta Elite (love the rubber matte surface feel, fits great in my ears, comes with wireless charging, but sound signature is geared towards the masses with strong bass, tamed highs and narrow soundstage with the mids positioned forward. Sound is acceptable to me, connection stability is decent, price is low, but I gave them to my partner).
I recently tried the Sony XM4 (sounded very close to the XM3, but slightly warmer with slightly more bass, the body is much better designed though) and the Devialet Gemini (probably had the strongest and best bass I've heard in any earphones, except for the Future Sonics Atrios, definitely one to try for bassheads) but decided against buying them.
I tried a few TWS from Chi Fi brands like Shanling (sounded off) and KZ (cheap with decent sound, but terrible connection stability) and decided to stick to some of the more well known brands.
