Newer Technology has announced its new line of iPhone accessories, which will debut at Macworld Expo later this month. The line includes the Speaker Dock & Hands-free Mic ($35), which features a Dock for using the phone for both calls and audio playback, controls for call and playback functions, and the ability to charge the iPhone while docked. It was originally shown in our 2008 iPod + iPhone Buyers’ Guide, alongside the new Mic Extender Cable ($15), which functions as both an iPhone adapter with in-line mic and control button and as an extender. Other accessories in the new line include a Headphone Jack Adapter ($8), an iPhone & iPod Auto Charger ($13), Bass Response Earbuds ($20), and iPhone Hands-Free Mic & Earbuds ($20). All products in the NewerTech iPhone Accessory line are available now, except for the iPhone Speaker Dock & Mic, which is expected to be available beginning January 28.
