The new Etymotic hf2 noise-isolating earphones ($179) are now available. The earphones feature a microphone and play-pause button like the original iPhone headphones.
The earphones have a 4 ft. cable and come with assorted eartips along with a filter tool with 2 replacements and a storage pouch. They work with both the original iPhone and the 3G, as well as the Blackberry Curve and other devices with a 3.5-mm 4-contact phone and stereo plug (like the newest iPod Touch and Nano).
Etymotic claims the hf2s have the same audio response as their well-reviewed Etymotic ER-4 earphones. About.com’s Home Recording review blog gave the ER-4s 4 out of 5 stars and had this to say:
The Etymotic ER-4 earphones has become one of the most talked about earphones for accurate sound reproduction. A favorite of many sound engineers and artists for both on-stage and off-stage monitoring, the Etymotic design – and the research that went into it – is the basis for most in-ear monitoring options today. These earphones are true audiophile quality; and with the optional ER-4p to ER-4s converter, they can be used with professional-grade headphone amplifiers for even greater quality.
