Disclaimer on the W3: the TF10 is my overall favorite pair of phones to date, and I HATED the Westone 3. Yes they are both V shaped and colored with big stages, but the presentation is entirely different, and so is the sound. The W3 has more depth than width and decent height for an IEM, whereas the TF10 is very wide for a universal IEM with less depth and height than the W3, depth is still decent but nit much height ; the W3 is more well-rounded but not as immediately impressive.
The W3 has a very immersive presentation but its sound signature and tonal balance are the opposite. The midbass is very exaggerated, not just for a BA but more than anything I have heard in relation to the rest of the spectrum, with the possible exception of the Sony XB500. There is very little subbass though, noticeably less than the TF10. The W3 tends towards sounding somewhat holographic like the SM3 but its really hard to appreciate because the midbass is so overwhelming. Honestly its what I would have expected from a high end Dr Dre Beats IEM. The sound is on the dry side with crisp treble that can be rather sibilant. The mids are recessed, vocals were consistently overpowered by the midbass in my listening. The mids and treble are crystal clear of themselves but personally I just couldn't get myself into the sound the way I like to with multi-BA soundstages with all if the midbass being delivered so up front and loud. IMO it is a very niche sound, probably not good for anything but electronic music and rap, and I personally found it very disappointing even with those. I can't recommend it when the TF10 is so much cheaper, more versatile, and comes with a replaceable cable. I'm sure for some people its the perfect IEM but I was very disappointed by it.
