As a reference wrt my music preference, I have had experience with Final Audio E3000, Ibasso IT01 and P7 wireless. In terms of sound signature I have liked P7 > IT01 > E3000.
3000 - I felt bit muddy, lacking instrument separation.
IT01 - was good (nothing upsetting) but had comfort issues. I feel straight down iems are be better choice comfort wise for me.
P7 wireless (in both wireless and wired modes) - is the best sound signature I have experience so far except the bass is more than I prefer. So I end up EQing it down a bit. Given what I read online and my personal experience, I felt Be's would be a great fit.
I recently purchased 'be' blemished version from periodic audio. Seriously, I can't tell what's wrong with them physically. But I feel low end lacking significantly (and I am not a bass head). I have tried all kinds of tips and even had them put through Jlab burn in track on sound cloud for about 100 hrs. Am I missing anything. I have looked at reviews and graphs and didn't expect it to lack in low end to my liking. I am using Iphone 8plus with apple audio adaptor which per the reviews are quite good and clean source for driving iems. I listen to mostly online music (320 kbps)
Should I do more burn in ? Some reviews mentioned over 200 hrs of burn-in but I am not too much of a believe of iems needs that much time to get better, atleast scientifically.
Any suggestions are welcome. I want to like these iem's since they are sooo comfortable and do well in other freq range.

I had an almost similar problem. I have a pair of "regular" be's, and, after just over a full week of "training" using real music AND after FINALLY completing my eartip search, I liked them so much, I got a pair of on-sale blem be's.
I really feel your pain with the eartip selection hunting. I tried all of the included eartips, liking the large foam ones best, but something was still lacking. I tried some from other brands and finally found that Comply foam 600 Isolation large worked best for me. (The same may not fit your ears, but something out there will.) The difference was immediate and immense. I cannot stress the importance of the proper fit and seal to providing good sound, especially bass response. In my 15 years of experience with iems, starting with the admittedly bass-shy original Etymotics ER-4s's, the single most important thing that makes them stop sounding like an old transistor radio, or good 3-way speakers with blown woofers, is the proper eartip fit and seal.
Transducers with real moving parts, whether speakers, headphones, or iems will have a "training period" while their moving parts get used to flexing the way we like them to. Some materials "learn" faster than others. Beryllium seems to take longer than most, whether from my venerable Yamaha NS-500 speakers with Beryllium dome tweeters (gone but not forgotten), or the Focal Utopias, or the Periodic Audio be.
My reference rig is a Furman 15/MIT cable/Melco/Moon Audio Silver Dragon/Chord Hugo2/JH Audio+A&K Layla 2 with Silver Dragon 3 cable. None of those ever leave the house, so I use the be's with either iPhone or iPad and the Periodic Audio Nickel amp for roaming.
If you are convinced that you have found the perfect eartips, but still find the bass lacking to your tastes, try the Periodic Audio Carbon. My mind puts the be in the frequency response sweet spot and the Carbon takes that and adds a subwoofer. (Your mind may interpret the same sounds differently.) I think both the be and C sound great with the Nickel amp from my iPad or iPhone (when I can't get to the Hugo2).
Happy Hunting. Don't give up, many of us think the be's are worth it to get the eartips right.
