Not bassy and not warm, yes, similar to Monk+.
Hmm. Monk+ are just Ok. Not bad but if they have more Bass and Sub-Bass and some thumping and also warmness and of course, slightly smaller size of speakers and slightly better quality of cable (they tangle badly), then I guess it will be huge improvement. I guess Monk+ manufacturers can upgrade it to the above level and easily cost $10-15 without any doubt and I am sure they will be able to sell them in same quantities.
Are you aware of any bud with above requirements?
