hf5 High-Fidelity Earphones

Superior Sound Clarity, Great Fit and Maximum
Noise Isolation
  • The next generation of in-ear earphones
  • Response accuracy of Etymotic's ER-4 earphones
  • Available in 3 colors - Black, Cobalt and Ruby
Etymotic's 5th generation of high-fidelity in-ear earphones delivers a near-perfect music experience, even in high surrounding-noise conditions.

hf5 earphones use Etymotic’s acclaimed tuned acoustic-insert technology for the clearest, truest sound you can find.

Research confirms that users choose lower (safer) levels when earphones seal the ear canal. Etymotic in-ear earphones are the highest-rated product on the market for passive noise-isolation.

The hf5 is compatible with all iPod™ models and music players that accept a 3.5 mm plug.

hf5 earphones have special filters that smooth the frequency response and prevent earwax from entering the earphones. A filter is located at the end of the earphone and is visible when the eartip is removed.
