    High Performance Drivers
    Etymotic invented noise-isolating in-ear earphones using balanced-armature receivers and established these speakers as the gold standard for high-definition, in-ear earphones.

    The hf series incorporates these high-performance balanced-armature drivers and their unmatched accuracy at an affordable price for everyday use.

    Best Sound Accuracy
    True high fidelity requires reproduced sound to be as close as possible to the sound of a live performance. Etymotic's earphones and headsets have the highest response accuracy of all in-ear earphones and headsets.

    Best Noise Isolation
    Etymotic's earphones have the highest noise isolation of all in-ear earphones, as measured by an independent laboratory accredited by the National Institute of Standards and Technology. Reduction of outside noise lowers the risk of listening at unsafe levels.
