  what was it about them that you didn't like

Everything.  Sloppy, loose bass (crackles, ugh) on tracks that don't have much bass to begin with.  Harsh, shrill treble.  Overall just a total disappointment.  I've owned other Grados as well (PS500s, 325is) and have heard others (Rs1i, Rs2i, GS1000i) so I'm not a Grado hater or anything, in fact I'm a huge fan of their cartridges and less expensive headphones (SR line). The Ps1000s were just a total let down, especially considering the price.  I wasn't a huge fan of the PS500s either, but I would definitely go for them over the PS1000s.  They were lighter, cheaper and almost identical sound, although a bit more neutral.  I tried the PS1Ks with a variety of amps, dacs and sources, they just sound terrible.  I don't think they justify even a third of the asking price (considering other options) and they aren't even close to being the best sounding headphone in the current Grado lineup.

Ksc75, not really a regret more of a disappointment. I bought two without listening to them first. I don't regret because of how cheap they are to buy. They sound thin, treble are too bright to listen to, and very little bass. Because of how bright they are you can't get any type of volume to them before your ears start to ring. I have my laptop volume at 10 and even then I think it's too much

Beyerdynamic T70. I love most Beyers but these were mostly awful. Good for jazz but that's about it. No bass, sharp treble. Very detailed and clear but no fun at all

I regret ever buying the AKG K167. The build quality was a joke.
 
Monoprice earbuds are also very overhyped. They sound decent but their form factor is atrocious and hurt my ears.

Klipsch Reference S4... One of my very first IEMs. Bad fit overall for me, won't allow to be worn over-the-ear because of its stiff cable. Later to learn that they are actually just Image S4 with just a bit lesser bass and better aesthetics. Another would be the Sennheiser CX-400ii, just bad sounding IMO.

I don't know what it is, but all the Sennheiser CXn00 series, where n is any number, seem dead sounding to me. Considering how nice my CX475 and CX275 sound I just don't get it.

AKG K240.

Bland, boring sound, and cheaply made. At $30 They'd be reasonable.

The AT W1000X really didn't mesh with my tastes, and probably is the closest thing to a regret I have, but I'd wanted to try them for a while and I'm glad I finally did.

Yeah I know! I was surprised too, but I thought it was really fatiguing, even with leather pads.

Ditto on the Monoprice.  The sound was OK; fit was terrible.  Gave them to my son, he loved them -- go figure!  Had a similar experience with the overhyped Koss DJ100s...yawn.
 
Haven't gone mid-fi yet on AKG but am looking at the K612 or Q701 vs DT880s.  FWIW, I've gotten two solid values on AKG's lower end stuff.  The K518 is a nice set of cans for $35 and I got some K340 in-ears for $20 that are good for working out -- once I swapped in a good set of eartips. Hoping this means good things for the 612s (or 701s).

No regrets. All part of the experience...
