Hello guys, my first post here!
In short about me: sold all my expensive stuff like Hifiman HE1000 and now enjoying $10 earbuds to the fullest

Before trying earbuds tried IEMs but they don't really work for me for few reasons, incl. health and comfort. Actually I'm very glad that flathead earbuds are still alive as they are very good alternative to IEMs.
I have read like 50 last pages, also used search through this thread extensively and for now ended up with VE Monk SL and I'm very happy with them.
However, I'm seriously looking for an upgrade, better shell materials or detachable cable would be great as Monk SL feels quite cheap (I mean, it is after all

) and easy to break. I'm very satisfied with SL's neutral-bright tuning, but a bit of refinement to the sound would be very much appreciated. Also interesting thing that I can use both MX500 and PK style shells (however PK is totally comfortable and thus is preferred while MX500 is not so much), but strictly without foams since they are making my ears itching, quite impossible to tolerate (and why would I if bare bud feels great?). Budget is until $50. Appreciate opinions.
