Klipsch® has 60-plus years of audio design experience, and it really shows in these professional-grade in-ear headphones. Each of the Custom-3's earbuds uses separate high and low-frequency armatures and a built-in crossover. The armatures are smaller and more efficient than the more traditional mini drivers found in many in-ear headphones, and they deliver transparent, natural sound with detailed highs and deep, satisfying bass.
Klipsch in-ear headphones use oval silicon ear gels that match the shape of the human ear canal better than round inserts. They give you an extraordinarily snug, comfortable fit and a tight seal that improves bass and reduces ambient noise.
Built-in bendable, over-the-ear wire clips hold the earbuds securely in place. You can even position them partially out of your ears so you can hear surrounding sounds a good safety precaution if you're jogging on a busy road.
