Ultimate Ears Metro.fi 2

Based on the same body as Ultimate Ears' more expensive Super.fi 5 Pro and Tripple.fi 10 Pro, the Ultimate Ears Super.fi 3 Studio was the highest end, and most popular Super.fi 3 line, now defunct. Featuring a single driver armature design, the Super.

fi 3 Studio features the same top-notch isolation as the rest of the UE line-up, making these a great option for replacing stock buds or headphones for travel and on-the-go listening. Sadly with such a low impedance compared to stock buds or full sized headphones (13ohms vs. 32ohms) a high amount of noise will be heard during low volume listening without a high quality IEM amplifier.
