Pros: Clarity, precision, build quality.
Cons: Comfort and fit
As a sound engineer, I am fussy about audio and the UE Triple Fi 10's have made me a happy man.
Right out of the box they sound fantastic, despite a slight problem with fitment. After a short play with the different buds, I settled on the Comply buds and they provided a decent seal.
Overall they are great, and I use them for listening enjoyment direct from my iPod, and also mixing on my laptop, and the resulting mixes prove the Triple Fi's are a good reference!
Now I just need to get some ACS custom moulds for them!
