Been a HF member for almost 9 years. Have had the best and the worst, customs, etc....SCREW $99! The TF10 is a STEAL at even $200!!
They are meant to be used with complys period! The bore is too large to be used with silicone tips. So once you are over that, comfort and fit is great and very easy to take in and out.
While I have always thought of W3 was my #1 favorite universal (ya don't see IT selling for $99)....
I personally find the TF10 a bit better for all forms of music except rap and hip hop. Bass is best I have ever hear. Extension and tecture is amazing. Treble is as good as anything else I have heard. Midrange is slightly veiled but I think this was done on purpose to keep the overall presentation smooth. For reference, vocals sound better with TF10 than W3. Soundstage (like W3) is huge...it's like wearing headphones.
TF10 combines the greatest combo of bold, fun and exciting while still being fairly neutral and balanced. But if you like forwards mids (Shure, W4) which I don't, you may want to stay away from TF10.
