Headphone Extension Cord
Review of the Sony RK-G138 Headphone Extension Cable

In this article we review the RK-G138 headphone extension cord from Sony.

A headphone cord is a part of the headphone that simply connects the headphone to an audio or video source. This is the main difference between wired headphones and their wireless counterparts.

While wired headphones use the cord to connect to the audio or video source, wireless headphones use infrared technology and radio waves to synchronize the audio or video source with the base station which then sends signals to the wireless headset.

Headphone cords come in different lengths and quality. The quality of a headphone cord improves the overall sound quality of the headphone and reduces disturbances from distortions characterized by contact. The length of a headphone cord plays a vital function for different users.

Some people might prefer a short cord which enhances ease of use with portable music devices when moving or performing exercises while others may prefer long cords for use when listening to music some distance away from the audio source in a more comfortable spot.

This has warranted the need for extension cords which can be used with almost all headphone types. Extension cords can be supplied with headphones or can be bought separately.

Many headphones which are made with short cords come with an extra extension cord. These types of headphones were made to serve the need of users who prefer short cords and those who prefer long cords with their headphones.

There are a lot of different extension cords produced by different manufacturers on the market. These extension cords may or may not come along with different sizes of mini headphone adapters for compatibility with different headphones.

Extension cords come in different sizes and lengths to suit the needs of different users. Buying an extension cord for use with your headphone can be a blessing as they come in handy anytime they may be needed.
