Vsonic and Hifiman Both available.

The only public transport that can reach me is KTM

Can also consider Superlux HD330. It's a Taiwan brand that produce headphones at cheap price but with good sound quality. I used to recommend it to my composers and musicians friends. Compare to other Superlux models, it's harder to drive but overall the sound is more balance. Suitable for sound monitoring.

If slightly over your budget, can consider AKG K240S. It's a very famous sound monitoring headphone that being used in music production and widely used in the world. It's slightly darker sound than other typical AKG headphones. If she is into music production later on and mixing own music, this is a good option.

If mic is important to you, then xiaomi piston is not bad. Auditioned it before. But if you do want to prioritise sound quality, you can check out these few models:
Superlux HD381 series (price around the same with xiaomi, SQ is a steap ahead, build quality wise xiaomi is much better)
Vsonic VSD1 or 1S ( good details IEM with neutral and balance sound), which I think the SQ is quite suitable for pop and jazz.
Sound magic and Xiaomi is towards more bass (large quantity) if compare to Superlux and Vsonic.

Actually I would think that your music source and DAC would play a more important role than the music file quality
Can consider getting a DAP or DAC/amp in the future when you are upgrading.

Can try Vsonic VSD1/1S.

audition it yourself is the best

For the price, I would say Superlux. But for the music genre that you listen to, probably hd681 evo is more suitable. More bassy and warmer, but it's not close back.
For close back, can try Superlux HD669, slightly over your budget can consider HD631 DJ

Not sure if I got it right. If you like emphasis on mid range, warm sound, less treble, slightly on bass, you can also try out IEM with typical England sound like HiFiMan RE400 or RHA MA750i if got chance. They are smooth, fuller mids, and musical.
I personally haven't auditioned EPH100 though.

Understand where you are coming from. But I guess what you need, is not only a bassy warm tone IEM, you need also an IEM with good quality of bass that clearly present the details of the lower mids and bass. can give KC06A a try though.

Haven't auditioned IM50 before.
can check out my short review about KC06A and GR07 classic.

no matter how much it leak, i think if you use it in the library, others might get annoy. but anyway you can still try it first if you want. it does come with velour pads.

If you plan to direct plug in to computer and hand phone, I would say get an easier to drive headphone. M50x + E18 is not bad. (E17 stop production). If you don't mind desktop unit, can also consider Aune T1 mk2 as dac cum amp.
M50x is not consider a bassy headphone actually. The SQ is quite decent at the price range and easily sounds good.

I'm not sure whether you want quantity or quality. Custom one pro though is a portable headphone, it has stronger needs in amp among other portable headphones. Direct plug in, the quantity of bass is actually quite a lot but very loose and blur and not solid. So when you mentioned the bass is not enough on COP, I am not sure whether the quantity is too little or it's not tight and solid.
If you use to Denon, you can go back for Denon. It's one of the headphone company that produce headphone with good bass.
If you are willing to try new headphone, can consider sennheiser hd598 as well. The bass is different from Denon. The bass with better surrounding, more loose and soft, overall is more warm and rich.

DT770 is higher range than M50x if drive well. A lot of musicians use DT770 for music production. It's quite accurate sound but hard to drive. It's won't be easier to drive than dt880 and dt990 actually. You definitely need an amp for it. Direct plug in might be a disaster

That's only on the condition without a decent amp

"Custom one pro bass not solid compare to m50x" This is only when COP is not being driven well actually.
If drive well, COP will sound solid and with good details. Overall its SQ is a step ahead than M50x.

Not sure how far do you plan to go. To me, DT770 needs amp that cater for big cans. At least a RM500 portable amp like Shonyun 306a or desktop amp like bravo ocean is needed. Or at least an audio interface. To get a good sound, what you need is not only an amp, but also a dac since it's the first point to provide sound signal. If you only have budget for the headphone and amp, then probably you can consider another easier to drive headphone and spend your budget on a DAC cum amp.

Not sure which model you have in the past. But the price for Denon D400 is very low now. Can consider it.

*just manage to audition Philips M1 today. I think you should also consider it. The bass is real good and easy to drive. Overall sound is more rich and meaty, with more punchy, tight and large quantity of bass compare to M50. Details wise, might be slightly muddy compare to M50, but very comfortable sounding.

There isn't any so call "best" earphone, all depends on your personal preference. If you like IEM that focus more on details, can consider superlux HD381 series. Slightly over RM100, can consider Vsonic VSD1.

If you like warmer sound and large piece of bass, around RM200+ can consider JVC HA-S500.
If you prefer a bit more on details, clean, direct with punchy and tight bass, around RM300+ can consider Beyerdynamic DTX501p

Can try out HiFiMan RE400, and RHA MA750.
RHA is more warm sounding and typical England sound. More to mids, smooth and rich. The strength is not on separation, positioning and details. It's with very mature and comfortable sound tuning.

RE400 is clean and refined. Not so warm, also more to England sound. It's also focus more on mids. The charming part is when the music flows out like feather, soft and smooth.
