Apple’s new Earphones and In-Ear Headphones with Remote and Mic are only partially compatible with the iPhone and iPhone 3G, according to a recently-posted Apple support document. The Knowledge Base article titled “Compatibility of wired headset models with iPod and iPhone models” explains that while the remote, microphone, and volume control features of the new headphones are compatible with the 120GB iPod classic, iPod nano 4G, and iPod touch 2G, the volume controls will not work with iPhone or iPhone 3G — only the playback remote and microphone. As previously revealed on the headphones’ product page, earlier iPod models will be compatible with audio only. Both the Apple Earphones with Remote and Mic and In-Ear Headphones with Remote and Mic are available for order now from the Apple Store online, and are listed as shipping in 3-4 weeks and 7-10 days, respectively.
