Wow that is quite the opposite from what I heard, the Triple10Pro has a really bad build especially when you compare it to the UE900. Personally I just don't like the fact that the body sticks out from your ears like a sore thumb :P
Why din't you keep the TF10? what did you upgrade it to?
Oh the tf10 were my play around iems. I sold those and went with the se535-ltd-j then the westone 4r.
To each their own. I was reay weary about the fit of the tf10 them when I got them I had perfect fit and it really aupriaed me I thought I would bs one of the ppl who have fit issues.
I purchased my tf10 when I had them for 110.00 shipped off here excellent price. Now they are being sold for double that.
