Okay ... finally got around to trying the dekoni Elite Choice Suede on my dt-880 (250)... as Z Reviews gave the Elite Choice Suede the HIGHEST rating for his evaluations of various dekoni. He also claimed them to be superior to OEM pads.
I have no idea what Z Reviews ear-brain system processes ... but I immediately HATED the Elite Choice Suede upon first listen ... sound became muddy and over-bassy on first listen. Kept them on ... maybe it's that Grado effect (hard and bright immediately after switching from most other cans like hd600 or beyer ... but leave them on for a bit and my brain likes what it hears). This was certainly NOT the case with the dekoni.
Believe it not, the original "OEM" pads are not genuine Beyer OEM ... they are cheaper Chinese eBay replacements ... and I don't remember exactly what OEMs sounded like but not far from the Chinese "OEMs".
The dekoni are NOT cheap and they are way over-packaged--you're paying for a glossy box, graphics, presentation and the "dekoni" brand name.... oooh .... ahhhh ... . HUGELY DISAPPOINTED.
