Noise-Isolating IEMs That Punch Above the Price

Built with a single balanced-armature driver per ear, the Etymotic ER23-HF3 IEMs deliver accurate sound and impressive noise isolation rated at 35 to 42 decibels. In fact, many have compared them to the legendary R4 in terms of sound quality. Head-Fi user mark2410 says, “If you … grabbed the wrong set one day, you aren’t going to notice immediately [or] at all if you’re not closely paying attention.” What Hi-Fi adds, “These really are exceptionally crisp and insightful headphones. They’re supremely tight and controlled right through the frequency range, with the kind of analytical nature you’d usually associate with a much higher price tag." The HF3 IEMs come with a three-button remote that’s compatible with iOS devices.
