hf Series Noise-Isolating Earphones
No compromise, high-performance noise-isolating earphones that deliver best-in-class benefits and superior value, perfectly matched to the latest product innovations from most music players that support a 3.5 mm stereo phone plug.
Why Etymotic?
Etymotic designs products to measure, protect and improve hearing, and enhance the listening experience of music lovers everywhere. Together, audio engineers, musicians and audiologists at Etymotic have generated over 100 patents issued and pending.
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.
