Pros: clarity and instrument separation. bass. highs are superba!
Cons: lacks transparency with mp3's even 320. ever so slight sibilance in the vocals sometimes
I must have HUGE ear canals, because with the large silicone tips provided in the box, I got a perfect fit with an impeccable seal! Now i simply get the most amazing sounds ever from an IEM i've owned, and i've owned MANY! I must amend to say that the simply stellar sound quality extends to FLAC (lossless) sources. The TF 10's tend to struggle a bit with mp3's. Even the 320 and V0 quality files. You lose about 10-20% of the sound stage and depth with mp3 files. Still....worth every penny, and I must laugh at those who complain about it being a bad fit or uncomfortable ect ect. I sleep with mine in. As i stated earlier I got an impeccable fit. I love my TF 10's. Now on to the Sennheiser IE80's and Westone 4's.
