Hisenior U4 - first impressions
I just got U4 two days ago and thought to share my first positive impressions here.
(Disclaimer: I paid a full price of ~200 $ plus two pins minus the cable)
Hisenior offers several models, U4 is their non-custom version of T4, a 4-BA model:

I started my order with A6, but the customer service, Gareth, was so great that I ended up with U4 (I was offered several nice options, U4 indeed suited my needs best for what I opted to pay).
Again, the customer service is really superb in all aspects (tangible and intsngible) and it matters.
For the option of custom colours for the shell and the top I was lost even in blue shades, finally ordering a frankenstein combination of four different blues - well, the end result is totally subtly unique and still simple blue
Unboxing: I really loved it, no boxes, just a nice case with a decent selection of tips and few tiny extras.
Build: no any problems the 0.75 2-pin connectors were tight for my common (0.78) 2-pin cables, but everything worked.
Fit: very nice small shell; spiral dots (or similar tips) worked well for me; used them comfortably for 3+ hours.
The sound is great so far.
Bass: is more or similar to AS16, a bit less than in C16, I could not perceive much difference with KZ/CCA here.
Mids: definitely a mid-centric IEM with ED and TWFK Knowles working together. "Smooth ambience" comes to mind.
Treble: I asked for the "most unleashed" trebles (at least in terms of not putting any dampers). I still can take a bit more. Violins sound closer to nice recordings rather than up close. Definitely, for most people it will sound very pleasing; for me - it is still more than I expected from Knowles, quite happy here.
Finally, in terms of the cost to performance, was it worth? For me - yes, definitely, since I got what I was looking for, but~200 $ is definitely a very competitive category with many other offerings of multi-BA IEMs.
I would be curious to know if someone can offer a comparison with similar Audiosense and BGVP models
Here is a picture of them:
