I recently bought two of them for a total of 22.5EU via ebay , including also VAT 24 % and handling and received in just 3 weeks
Tested together with my DJ81 from AKG a nearly bassy headphone and a splitter box my Amoi DSP and a radio with good audio giving these results
The sound give some voice presence over the 81DJ with a full span that is slighly lower than the 81
I didnt manage to ad d the sponges ovr the buds > so many tries...
8/10 between both
