I just bought some Senn IE7's from amazon for 209$ price was alright. My list of phones i use are SFi-5's and PFE's. The UE's are just dated they'er the old style, and the PFE's sound nice but i need more power. I use a Sansa Clip and Cell Phones. Please tell what i can expect and what i should...

Im looking to spend around $200 for a new mid range IEM. I have a fast paced job so fit is important to me. Here is the list i have so far. Klipsch Custom 3 Westone UM2 Phonak Audeo PFE Q-Jays
