About Etymotic Research ER4XR With Etymotion Wireless
Over 30 years ago, Etymotic invented noise-isolating, in-ear earphones. Etymotic’s original design, developed for auditory research and hearing testing, used balanced–armature receivers and established these speakers as the true reference standard for high-definition, in-ear earphones. Paired with the new Etymotion Wireless Bluetooth cable these earphones are unstoppable and sound better than anything else on the market today. With built in functionality to answer calls, play/pause, and change tracks it’s the ultimate in audiophile portability.
