Great review Tom! Thanks
I just picked up the FRD60 for 17 CAD (hehehe, thank you Futureshop Management and dishonest people opening boxes to either try/steal them) since I couldn't find the 70s or 80s stocked in any physical locations. None of the included eartips fit well, either too big or too small. I found the Sony Hybrids (med) fit well and am using those. Comfort and seal is now fantastic.
Out of box - I found them to be way too bright and bass free. Given they are JVCs, I let them play overnight (I know it is recommended to let them play for a long @$$ time...). Tried next day, same thoughts. Very underwhelmed. Then I figured I would try my hand at EQing them. What needed to be addressed? Bass: bump up the low freqs a couple dBs. Treble: drop the high freqs a couple dBs. End result....DAMN! These puppies shine with some minor eq...what a turn-around. The bass is unreal, and they have a nice open soundstage which threw me off initially. I read back around ~pg 40 that someone felt they were bass cannons. Yes....they certainly can be. Stock tuning seems very treble/mid focused imo, but they are very receptive and sensitive to eqing in a good way. Can't wait to see what more 'burning' does. 17 bucks well spent!
