Ultimate Ears has been a familiar name to musicians and other audio professionals for a decade, but the company has gained quite a following with its consumer line as well. Earphones in its various lines range in affordability and scale nicely, from discerning listeners to audiophiles. At the bottom end, you have the MetroFi line, which has recently enjoyed a refresh in the form of the 220 and 170 earphones, the latter being the subject of this review.
The MetroFi 170 Noise Isolating Earphones are the cheapest set in the Ultimate Ears family and come in two versions: a standard MP3 player model for $49.99 and the iPhone-friendly 170vi, which includes an in-line mic and sells for $10 more. Either set is a great starting point for picky listeners who don't have a lot of cash to spend on replacement headphones for their MP3 players, but buyers should be aware of potential fit and durability issues.
