This overview of current headphones will help you pick the right one from the overwhelming flood of styles and models of corded and wireless headphone products.

There are many different designs and styles of headphones on the market starting with in-ear headphones as being the smallest headphones, some of which have a bracket that is worn around the ear. These type headphones can easily be stored in a pocket. They are often bundled with iPods or MP3 players. The next size up are lightweight headphones that sit on the ear and are connected by an elastic frame. This headpiece either sits on top of the head or wraps around the neck. If your budget is tight then you should probably focus on these types of headphones. They are the least expensive of all models. Some models provide insulation from external noise to some degree.

Medium-end headphones are an option if you are able to spend a little more and offer better sound quality. The earpieces have ear cushions to improve the wearing comfort. These ear cushions are either located on your ear or around your ear. Many people prefer the second type since there is no pressure on the ears. If you feel you would like to go with this type of headphones, you will then need to decide whether to go with an open, semi-open or closed design. An open design means that the audio can penetrate from the transducer to the outside and also cross-couple into the other earpiece. While some people feel that an open design sounds light, a closed design will tend to absorb exterior noise more and provide better insulation between the two earpieces.

Most of today's headphones are so-called dynamic headphones. Dynamic refers to the type of transducer that is used. The second more expensive type which requires special headphone amplifiers are static headphones.

Wireless headphones eliminate the headphone cord. Bluetooth headphones are another option to consider. Bluetooth headphones are a type of wireless headphones which are designed for Bluetooth-enabled devices. Such devices include cell phones. The operating range is typically only 30 ft or less. Bluetooth headphones do normally not offer audiophile sound quality.

Other wireless headphones often work at 900 MHz and use FM transmission. These headphones are the least expensive wireless option. More advanced digital wireless headphones work at 2.4 GHz or 5.8 GHz. FM wireless headphones have noticeable hissing and audio distortion. They are also prone to interference from other wireless devices.

Digital wireless headphones, such as Amphony headphones, encode audio data prior to the transmission. This makes this type of headphones superior in terms of sound quality. Digital wireless headphones are also fairly robust against interference. Some digital wireless headphones work at the less crowded 5.8 GHz frequency band. This band offers less competition from other wireless devices compared to the 2.4 GHz band.
