Drop + Sennheiser HD 6XX vs FiiO FT1

“I'm not sure if the HD 6XX can really take too much EQ in the sub-bass because it could start to distort. The Edition XV not only has more sub-bass out of the box, but could probably handle a bigger boost in the sub-bass as well. In fact, poor sub-bass performance is why I sold my HD 660S2, as it just got destroyed by the Ananda Nano even though I put EQ on both of them. And the HD 660S2 is actually better in the sub-bass than the HD 6XX. Luckily, Sennheiser has been cooking recently with the HD 490 Pro which has some more sub-bass than the 660S2 and comfort better than the Ananda Nano.”

“Ignore the idiots OP, just because some people got a good set doesn't mean the QC doesn't seem to be shit and there are some people who just can't accept that it's not user error. FT1/FT1 Pro QC just seems to be a hit or miss. I have the same issue as you, got my FT1 a week ago, the screw on the exact same spot is broken for me. I recorded the whole thing, from unboxing it to discovering the right ear cup was loose, then finding the broken screw and the washer in the box. Packaging was solid, the case is amazing, but that nut was broken inside the case. I am waiting for the vendor to look at the whole video and get back to me about a possible replacement, but its Christmas week and I am stuck. It's bad for you though, mine's just a personal splurge and not a gift for someone else.”
