The M1, M3, M760, and T-38s are all well worth the investment. I've invested in head-devices costing upwards of $200 and been dissappointed. There's no accounting for taste and I know mine is definately a little weird. Recently I've discovered I prefer the sound of $10 no-name Urbanears ripoffs to my SHURE E4c. And this is after the Shure's broke and I have already paid to get them reshelled!
For the cost of a TWFK Knowles IEM (for which I bought and didn't like), I can buy 2 each of the buds I mentioned from Dasetn - and be more satisfied with the sound plus not get all bent out of shape when I eventually break them - I have already broken one of the Dasetns, and it is no big deal!
For price/performance ratio, these earbuds from Dasetn cannot be beat.
I always break my earbuds - they are used for over 40 hours a week in my ears - walking around and getting tossed in the car - plus they have to endure another 12 hours week in public performance scenarios as DJ cans and IEM stage monitors for vocal performance.
They fit my purposes very well and their cost is finally in line with something I will eventually break.
I have not found an IEM or other earbud costing more than $150 that sounds better or equal to the Dasetns. But also realize, I've only spent that much on 3 pairs that eventually broke. I've spend that much on cans - and they sounded better - but they also broke.
There is probably an expensive bud that blows all the Dasetn's away, but I'm not in position to endlessly order different expensive buds and try them out like I am able to do with the Dasetns.
If someone has the money to invest in more expensive output listening devices - then they probably will be able to find something that sounds better. However, buds are not like speakers in that you can go to a store and audition multiple pairs - and the speaker setups are also fast dissappearing. I used to remember specialty sound stores with soundrooms setup - I don't see them around anymore like I used to.
Another thing that really surprises me is that these are Chinese buds and that they are listenable and sound great. If I spend the same amount and go get a pair of buds or IEMs from a local store, they will not sound as good - but they might be as well made.
For the longest time, I was used to inexpensive Chinese speakers/iems/buds/cans that looked like a more expensive brand but sounded awful.
Then I saw buds for $10 or so from HiSoundAudio, Vsonic, and Sunrise - I took a chance and ordered them and were SHOCKED that they sounded so good for costing so little!
The same thing goes for the Dasetns - all well worth the money. All sound great.
But they might not be to your taste. This is to contrast it with something like the $5 buds I get at the $5 store- that just sound awful.
