The Klipsch Image S4A takes everything we liked about the S4i, and brings it to the Android universe. Like the S4i, these are lightweight in-ear headphones offer great sound, good noise-isolation, and a snug fit, all at under $100. This version adds an inline remote/mic that will work with current Android devices. A free downloadable app lets you remap the buttons on the remote, offering a degree of customization that you'll find in few other headphones. If you don't have an Android phone, and want the same sound quality, go for the S4, which is usually available for about $30 less than the phone-specific models.
