So i claimed the warranty on the TF10's and purchased myself a pair of UE900's.
I would like to say that i now realise the tf10pro's were a legendary piece of work.
I don't know how much of a burn-in these need, or how much time my ears need adjusting, grains of salt are needed as my views might change.
Rig: Z-series walkman (FLAC) > E17 > UE900.
First thing i noticed was the volume, on my E17, the tf10's were loud at 24, the ue900's needed a 28 to reach about the same loudness as the tf10's.
Bass, there is bass, a tad more than the tf10's, BUT i feel that the ue900's don't have quite as much control as the tf10's. The tf10's had more oomph, more punch, the ue900's have bass more than anything else, it has more extension than the tf10's, but there's just a lot of it. The ue900 has more sub-bass, the tf10 has more mid-bass, the tf10 has a round feel to the bass, the ue900 has a wall of bass.
Mids, they definitely fixed the recessed mids issue of the tf10's, vocals aren't drowned out by the rest of the spectrum, as with the v-shape of the tf10's. The ue900's has a sloped sound, bass the most, mids slightly more than the highs, highs being the least. Due to less highs, the mids have a bit more room to stretch at the upper half the spectrum, but feels a little cramped near the lower mids, where it fights with the lows for room.
Highs, this is where i'm irked, it's probably because i'm a treblehead, it definitely doesn't have a crispness on the cymbals, if you found the tf10's sibilant, these don't have that. I'm mostly an electronic music listener, so everything treble has some edginess to it. There's definitely a bit more micro-detail, but it lacks volume, so you have to listen out for the details. The tf10's has the trebles presented to you effortlessly but not as much extension as the ue900's
I feel there's about the same amount of high as the mids, mids having slightly more pronunciation.
There's a larger soundstage with the ue900's, everything seems a bit further away compared to the tf10's, perhaps this is where the problems with the treble lies, but it doesn't explain the bass. I can't hear any improvement in the instrument separation, seemingly the bass fill all the gaps.

Shun me as you see fit, but there's too much bass, and not enough of everything else, perhaps i should try blocking the pinhole,
overall it really sounds like a fun iem, but...
I would really like to get my hands on a pair of ex1000's.
