So I've had this universal demo review unit for some time. I have the vented 'bass port' version. I've had a chance to really give it a listen over the past few weeks.
I have to say I really don't like it with the bass port. The bass is heavy to the point of sounding like the driver is bottoming out. Over the past week I've just taped up the bass port and listened that way. While I think this wouldn't be 100% identical as listening without a bass port (the tape itself might act like a little
passive radiator, like a drum skin) it should be pretty darn close. It's still very bassy even with the bass port taped over, but I like it since I certainly don't mind bassy in-ears.
The BA driver is certainly doing its job and the whole thing sounds very cohesive and surprisingly well integrated. It sounds at least well integrated as the UE900 and certainly better than the XBA-40 / Westone 40 I have on hand. I'm curious if anyone knows if there is a crossover in this thing or are the two drivers wired in parallel?
Certainly there is a bit of broad high frequency emphasis, but it doesn't sound too extreme to me and not objectionable to my ears. The whole thing sort of reminds me of a CK100 Pro with more bass and less strident treble.
I'll have a full reivew video up eventually, but right now I am impressed enough to seriously consider getting my first custom considering the decent pricing
