Having premium sound shouldn't mean paying a premium price. PureGear provides the same quality and features found in the most popular high performance in-ear headsets at a fraction of the price. Now THAT'S music to your ears. With the built-in high grade microphone, you can make and answer hands-free calls without worry. Compatible with all standard 3.5mm headphone jacks (like the one in the iPhones or Droids). You can also forget about spending precious time on untangling the knots from your headphones because these are made with a 3 ft. tangle-resistant cable. Ear sizes and comfort levels are different for each person, so we don't think you should be limited in your options. That's why there are two additional pairs of ear gels and a protective case to store everything.
