Would iPhone 4S/iPad be able to drive tf10? really regret getting rid of Cowon D2 and might have to buy another now.

 
 
You can power the TF10's from pretty much any pmp, they only have an impedance of 32ohms.

Just an FYI, low impendance doesn't necessarily mean easier to drive... you need to take Sensitivity into account too...

Well I haven't found any IEM's that I have or have heard with an impedance or 32ohms or lower that couldn't be driven fine by a pmp with ease, can you tell my of a pair that has low impedance but are hard to drive.  Most that I know of with lower impedance's have a sensitivity of around 105 to 110dB give or take a few.

IMO the only issue that do you do is change the stock cable for better sound and principally for ergonomics, the stock one is hateful !!

yeah forsure. A definitely forsure with the ipad.  The tf10's are really easily driven.

iPad...Maybe. If you can run a DT770 PRO 80ohm out of it just fine, then a TF10 will be fine. Reason for this...

 
Peaks at 64.5, bottoms out at 6.5. Probably needs an amp...
