    Best Sound Accuracy

    Etymotic hf2 earphones deliver 85%+ response accuracy from 20 Hz - 15 kHz. hf2 achieves the highest output sensitivity in its class with 105 dB SPL sensitivity at 1 kHz at 0.1 mV, thanks to Etymotic's Accu-Driver high performance, precision matched, balanced armature drivers.

    Best Noise Isolation

    Etymotic's specially-designed earphone tips create 35 dB - 42 dB of noise isolation, which is the highest documented noise isolation of any earphones or headphones on the market today. This earphone headset comes with several types of eartips--3-flange, foam, and glider--to help you achieve a comfortable fit while retaining maximum noise isolation.

    Works with "AWARENESS! for Etymotic" iPhone App



    Etymotic mc2



    AWARENESS! for Etymotic is an innovative earphone app for anyone who uses an Etymotic headset and needs to hear sounds around them. AWARENESS! for Etymotic listens to your surroundings while you listen to music, and allows any sound louder than normal background noise can be heard in your earphones. From hearing that truck while it's still down the road to hearing when someone asks if you'd like a cup of coffee in the office, or when the phone or doorbell rings at home, you can maintain spatial audio awareness for better safety in any environment.

    Use with music, videos, games, and audiobooks while traveling, in the office, at home and at the gym. The app works with all Etymotic headsets (except Bluetooth models), and works best with noise-isolating headsets such as the Etymotic hf2, hf3 and mc3.

    Upgrade to a CUSTOM-FIT

    Custom molds can be made for all Etymotic earphones and headsets. CUSTOM-FIT molds enhance your listening experience. They provide a comfortable, secure fit and do not alter the exceptional sound quality of the earphones. Register your Etymotic headset at and print out a voucher. Find a network provider on the CustomFit page who can make impressions of your ears and order custom molds for your Etymotic product.
