The sound isolating design blocks most background noise.
Excerpt: These Shures come with a selection of buds of various shapes and sizes, but none make the headphones as easy to fit as the Sennheisers or Klipschs in-ears at this price-point.

Pros: Excellent noise insulation, good detail and clarity
