The good thing about cordless headphones is that you do not have to be tied down in a specific place to stream and listen to your favorite TV shows and top choices in music – you are entirely free of the wires that are likely to get tangled and keep you from enjoying mobility.
The opportunity to freely move around was the first consideration that headphone designers and inventors decided should be a priority when working on their revolutionary wireless headsets. For convenience’s sake, you also do not have to turn your audio players on full blast just to hear your favorite music from the next room.

About Headphones: Wired, Cordless, Wireless, Portable
Cordless or wireless headphones are a pair of small loudspeakers that transmit information (in the form of the audio signal, or music) from a signal source radio or other audio players (iPod, MP3, MP4, etc.).
Headphones can be connected through the conventional wires that may span a considerable length but advancement in technology now offers us cordless or wireless headphones, thus, portable in nature.
Hence, cordless stereo headphones are free from any wire connections but they still have the capacity to receive radio or infrared signal encoded from a radio or an infrared transmission link (made possible through wireless applications like FM, Bluetooth or Wi-Fi). Sound technology nowadays has devices and applications that enable powered receiver systems of which a headphone could be a component.
Thus, cordless headphones are considered to be portable devices in the sense that they can be self-contained on their own and can be used through wireless technology. It is for this reason that they are especially useful for media communications.
Even though most of the time the word cordless is sometimes associated with the word wireless, there is still a fine line that differs one from the other. Cordless, literally “without a cord” can be wireless.
The word “wireless” is a description that is attributed to an object where it uses some form of energy (radio waves, infrared tech, Bluetooth tech, etc.) to transmit or transfer information. But for convenience, it is sometimes understandable that the two can be interchanged with one another.
One of the best features of a cordless headphone is that it allows greater mobility and flexibility for its users, and thus, it is convenient and comfortable to use in everyday activity.
