@TEOSJ,
I think for a bassy pair of headphones, the Alpha & Delta AD01 is very well done. I think on this sort of enthusiast website, a bass-focused sound signature will generally get viewed slightly negative (fairly or unfairly), except by more basshead enthusiasts. I do think that its overall sound signature will be very popular among normal consumers, so reviews here with pickier specific sonic preferences may be a bit inaccurate for wider tastes.
I did try to write my own review to be a bit less influenced by sound sig preferences, but it is hard to completely remove subjective bias when pair of headphones does not fit personal tastes.
thank you for this opportunity & appreciate the in-thread community involvement.
cheers!
