Got my Crazy Cellos from the 11/11 sale. Only took 12 days to get to Australia.
OOTB with standard tips that were on them. slightly bassy sound with a nice smooth midrange, but great accurate soundstage. Next Tried the 2 coloured wide bore tips that also came in the package and boy they were poor. It did bring out the clarity of the mids/treble but Sucked the life out of the bass. took them off straight away.
Decided to tip roll and went with the smaller double flange tips from my RHA TZ20i's and boy did i find an absolute sweet spot. Bass isn't as dominating but man those smooth mids came out to play and show their potential. Those mids! Played some Billie Holiday - But Beautiful and Billies voice is just so emotive and the cellos bring her voice up on stage with the great soundstage the instruments back her up perfectly. Wait till you hear the trumpet solo just take over smoothly at 2:35.
Next, throw on some Far East Movement - Basshead and the bass will blow your mind away without sounding too boomy (with double flange) . Went back to the original tips and it does lose a bit of its magic, sounding a bit too bassy for my liking.
So i can say so far from the limited time i've had with it, i think they live up to the hype with a big disclaimer that these are EXTREMELY TIP SENSITIVE. and personally prefer DOUBLE FLANGE tips (mine from the RHA T20i).
Also one big gripe with them is that is almost impossible to tell between left and right with the L and R markings extremely tiny on them.
I believe a poster before who had them also said that double flange seems to be a great fit for the Cellos. Too bad they don't come with them.
Anyways will be very interesting to see other peoples views on them when they start getting them.
Here's a pic with the Cellos + my RHA T20i small double flange tips.
