They are made from studio-grade components and feature a high-power mini speaker, with balanced armature technology, for an extended frequency response and increased audio clarity. These earbuds weigh only 0.9 oz (28 g), making them one of the lightest pairs on the market. They include a carrying case, and a cable spool to keep the cable organized. Shure E3 earphones are considered a more expensive set of earbud-style headphones, and retail for around $179. While this is a high price for earbs, it still is a cheaper alternative to high-end models such the Etymotic ER-4P that retail for $299. Justifying this cost are the improved components, and sound isolating technology that result in a higher level of audio clarity than cheaper pairs.
