Agree. And even more interesting, I can rarely see ue900 for sale from main earphone dealers, such as amazon, earphone solution. So where could you get it at that price from? As for as I know,ue doesn't plan to discount ue900 this year according to the announcement from Ue's official facebook.
We can only guess... but the UE 900 are no longer available from Logitech UK after %45 off sale in the last 2-3 weeks and Amazon UK isn't selling any... Actually just checked, they have 1 left, someone probably cancelled the order. Anyhow, I read the UE 900 are good IEM, ljokerl reviewed them and rated them pretty high but then again he posted the UE 900 vs the UERM:
UERM Demo vs Ultimate Ears 900 ($399)
"This one was a disappointment. I wasn’t expecting great things from the UE 900 compared to one of UE’s flagship customs, but even Rin’s modified TF10 held up much better than this. Frankly, next to the UERM, the UE 900 – a pretty decent earphone on its own – sounded like crap. Overall clarity was nowhere near the UERM and the bass sounded boomy and unrefined. The only thing the UE 900 had going for it here was good bass extension.
The upper mids, which I’ve always thought were dull and lacking in energy on the UE 900, seem especially veiled next to the UERM. The UERM is flatter through the midrange and sounds much more transparent as a result. The midrange, and vocals especially, come through much clearer. The UE 900 gets better from there – the treble and presentation really aren’t bad at all, but there is just no comparing these two in overall realism."
I know the UERM are in totally diff league... but it's a good read.
