I've found the TFZ King Pro a good representation of what high fidelity is all about. The full power and amazing detail come shining through with all decent sources. Additionally, the earphones deliver stunning localization and discrimination among the various musical components (voice, instrument, spacial elements, etc.), no matter how complex the arrangement. Even non-musical audio, such as complex layered soundtracks, intimate dialog, and natural ambient sound are reproduced with deeply satisfying accuracy and clarity. Listening is a joy with these earphones, an experience both revealing and deeply musical. All of the above WHEN they fit right. Which is why four stars instead of five. Fitment with these phones is tricky. I prefer silicone tips (foam tips botch up the sound, imo), and found the provided tips only made an adequate seal part of the time. The seal is easily broken, sending the superb lower octaves bye-bye. UPDATE - tips designed to be compatible with the UE-600 earphones, available from earphonesplus found to work very well with the Kings. The 'phones also look good, are easy to clean, and seem fairly sturdy. Reference-level performance at a reasonable price.
Rathmas925Certainly: earphonesplus.com Searching for the perfect fit for best performance is a bit like the search for the Holy Grail, or maybe "I Can't Get No (Satisfaction)". Nonetheless I keep trying 'cause once you get it right, the results are as dramatic as turning on the lights in a dimly lit room. Even if you do get it right sound-wise, there may still be problems with comfort and/or working loose/falling out - particularly with bulky, large-diaphragm IEMs such as the Kings, as well as other IEMs I've tried. Interestingly, this very evening I received some SednaEarfit XELASTIC eartips from 46audio.com. which are my latest attempt at the grail. Those results are for another time - I may post a review at audio46. Thanks for asking, and good luck.
