I used whiterabbit for my Tenores 1 month ago, payed 70$ with shipping, a little bit on the expensive side but fortunately I didn't had to pay any customs. They deserve any cent and alot more imo.
Right now I can say that this little phones are the perfect mix that I like with bass extending very low but with the perfect quantity for me, mids and female vocals especially are outstanding and very relaxed, detailed and extended treble that never become sibilant. They are so easy to listen, never becoming offensive or harsh. They really opened up now, I think I have more than 200 hours and they are sounding much better than incredibly great sound I heard right out of the box already. Make no mistake, this are not bass shy phones and I listen from blues to rock, metal, popo, electronic and trance. Each and every genre is brilliant handled by this gems.
