Product description from B&H Photo Video:

The hf2 in-ear stereo headset from Etymotic Research provides the terrific audio quality you’ve come to expect from Etymotic, and adds an inline microphone and control button for use with music-enabled smartphones, such as iPhones and Blackberrys. The balanced armature drivers
deliver high-fidelity audio directly into your ear for an immersive listening experience.

The different sizes of eartips allow you to find the perfect fit for comfort and noise isolation. By creating a seal in the ear, similar to an earplug, the headphones can offer terrific noise isolation without adding the bulk and batteries required by active noise cancelling headphones. The mic/button unit lets you answer and end calls and control music playback directly from the headset.

The cable provides plenty of slack, and has a Y-slider for adjusting tension below the chin. The 3.5mm stereo mini plug provides compatibility with MP3 players, CD players, iPhones, Blackberrys, and more. The headphones come with a set of replacement filters, designed to keep earwax and debris from entering the headphones. A storage pouch is also provided.

• Balanced armature drivers provide high-fidelity sound with a wide frequency response • In-ear design with assorted ear
tips provides a secure and comfortable fit with a high level!
