To put my experience into perspective. I've tried the M1, M3, M760, and TG38s all from Dasetn. I've also tried almost every earbud from AIWA, Sony, Phillips, JVC, and Panasonic that cost less than $20. I've tried $10-$20 buds from VSONIC, HisoundAudio, and Soundmagic. I've also tried a YUIN OK3 and dollar store specials. All the one from $10-$25 sound about on par with each other - nothing spectacular but nothing awful or offensive. Some are better than others and some genres. All the dollar store special ones or ones that come free with pawn store players sounded awful - but some of those cheepies were pretty. The Yuins weren't worth the price they were asking for them, but they did sit nicely with the other $20 buds.
My favorite buds are still Creative Aurvana Airs which hover around the $100 mark give or take. The Aurvanas sound better than all of them - but cost over 3x as much. So even though the Aurvanas clearly outclass all the other buds by a wide margin, I don't get 4x the sound quality even though I paid 4x as much. I would say that the best of the $20 earbuds are between 60-70% the quality of the Aurvana Airs. So when I pay 4x more for a pair of earbuds, I get less than 2x a bump in sound quality.
However, even a relatively Cheap set of cans from Superlux for $25 sounds better than all the ones I mentioned before. But then a $200 of cans from VMODA sound better than the $25 set from Superlux - but do not sound 8x better.
If you have the money to spend - a $200 pair of cans or buds is worth it. But if you only want to spend $20, you can still find pretty good sounding buds - but they do not sound better than a set costing $50 or $200.
This is my experience, and yours might vary. I know some people who love the sound of their stock Apple Buds and don't have the desire to upgrade. I've offered my cans to these people and they do admit that a $200 pair of cans sounds better - but do not need to upgrade in sound quality for what they listen to their music for. Plus they don't want to go around looking like Walter White.
If I could be happy with a $10 pair of buds, I would have saved myself a lot of time and money. As it is, I have more sets of things for my ears than I do have relatives. Everyone in my family and their kids and parents and grandparents - and all their pets could have a great set of cans/buds/iems and a backup. I've got way too many. And don't get me started on the DACs and amps. . .
