Can wireless headphones be used with a headphone jack?

Wireless headphones are designed to receive a signal from a transmitter connected to the device. Most of them are not equipped with a cable, in which case the answer to this question is no (assuming that the question is whether wireless headphones can be connected to an audio device via a cable).
There are, however, some headphones that are both wired and wireless, in which case the answer to the question is yes. There are a number of Bluetooth headsets and other devices that offer the option to use the unit with a cord, including the Sleek Audio SA6 and SA7, the Motorola HT820, Motorola S805, Jabra Halo, Nokia BH-905 and Logitech G930. Quality varies amongst them and quality is usually always less when used in a wireless mode.
