"Brilliant SQ, Value for money"5.0 starson by shubhangam
Pros: Great sound stage, imaging and instrument separation.
User customizable using the provided filters (grey - focus on highs, black - balanced with fuller bass).
Cons: Filter choice makes you keep switching.
Thin bass using grey filters.
Summary: In my opinion, for anyone looking to upgrade from stock earbuds or cheap IEMs, you should look no further and buy the Phonaks instantly. This 150$ will be the best you'll spend in a while.
Also, if this is your first IEM (In-Ear-Monitor), you may have some discomfort issues for a day, or two, stick with it, and let the brilliant music shine through!
