The basic earbuds have no controls. They ship with all iPods except the third-generation iPod shuffle, iPod touch and iPod nano which are shipped with the newer Apple EarPods made in Taiwan rather than Japan.
The third generation can be identified by the white border around the speaker and the left and right markings on the front (rather than on the back).

Apple EarPods (introduced on September 12, 2012) first shipped with the iPhone 5 and feature a remote control and microphone. They also ship with the fifth-generation iPod touch (without mic) and the seventh-generation iPod nano (without mic). They're also sold independently. The Apple EarPods are Assembled in Vietnam.
All but the basic earbuds have control capsules allowing users to adjust volume and control music and video playback, located on the cable of the right earpiece; those "with Remote and Mic" also include a microphone for phone calls and voice control of certain devices. Users can adjust volume, control music and video playback (play/pause and next/previous,) and record voice memos on supported iPod and iPhone models and Mac computers. There have been many reports of moisture problems with the remote/mic earbuds. The original iPhone and iPhone 3G came the iPhone Stereo Headset, a push-button and microphone on the right side of the headphones (there is no volume control, and only limited control of calls).
