Here's a pm I sent to a fellow head-fier that sold me the W3. Comparing the W2 and the TF10. Hope it helps anybody that's considering the 2.
"Alright, I told you I'd give you a more thorough review of W2 vs. TF10 when I get sometime. I did a bit of A/B yesterday and overall I think I just enjoy the W2's more laid back presentation a lot more(keep in mind this is a guy that really loved the RE0's low bass presentation, though the W2 is both more spacious and has an adequate bass)
Alright
Bass: TF10 probably has this one, much more punch, ever so slightly faster(maybe a mirage because W2's bass is less present and I might be less sensitive to some bassy sounds). Can't really comment on the extension as my hearing don't really go that low unfortunately due to blasting music as a youth.
Mid: TF10's mid is severely lacking for me and one of the reason I am probably going to sell it. W2 is about perfect in that aspect, not too forward nor too muted. Somebody with more experience(I think Spyro) said that the W2's mid is a bit forward, but to my untrained ear they sound very natural. Everybody from Robin Pecknold to Alison Krauss to Lucia Popp to whoever the headguy in Wilco is sounds fine. On the Magic Flute with Lucia Popp and the Philharmonic Orchestra(conducted by Otto Klemperer) record I wish that the vocal would be more upfront on songs that's more vocal centric(like the Queen of the Night) but the presentation is natural and puts you in about 5th row at the show(more about soundstage later)
High: TF10 wins this hands down, it is definitely sparkier. W2 is not bad in this, it's just that it is really hard to top the TF10's high
Soundstage: Both has large soundstage. The W2 is more natural to me because it doesn't sound like they shoved the lead singer into a closet in the back of the studio and make him sing from there and without the huge bass I can make out instrument better. But either has fairly big soundstage.
Comfort: I have said that the TF10 fits fine with me with the flip mod, they don't fall out but because the earpieces are so big they become ichy and hurts my outer ear after about an hour. The W2 is at least 1/3 smaller in size and(completely unscientific estimate) 1/3 lighter. Is more ergonomically designed and fit much better. My right antihelix(look it up on google, I didn't know what to call it either) still hurts after awhile but I think either 1)I'll get used to it or 2)I'll find a better fit.
Misc: TF10 is detachable cable, straight plug. W2 is non-detachable(but much less microphonic) cable and L plug. TF10 has a MUCH nicer case, but the W2 is serviceable. I hardly use any of the accessories after I find my tips but besides the W2 having more tips I'll call it even. Oh, almost forgot, a potential biggie, the W2 don't sound very engaging with some badly produced music but the TF10 is almost always engaging(too much sometimes I'd argue) Haven't had problem with low bitrate files but most of my mp3s are at least 192 if not 320 and that's not too bad.
Testing environment: Straight out of iPod Classic 6th generation 80GB, mostly lossless files but a fair amount of 320kps and 192kps mp3. Listens to mostly laid back(read: non-metal or hardcore) rock, some country, classical, jazz and an occasional rap album or 2. Sorry but my vinyl player is with a friend so I can't test it out of my old school Yamaha amp...
Hope this helps you, personally I can't see how the W3 can be better, we will see soon...
