An overview of the hottest wireless headphones.

By Gunter Fellbaum


Looking for a new pair of headphones and overwhelmed by the flood of models of regular and Bluetooth and cordless headphones? I will give an overview of today's models to help you pick the pair of headphones that is right for you.

Headphones are available in many different styles. In terms of design, the smallest type headphones are in-ear headphones which are plugged into the ear, some of these have a bracket that wraps around the ear. These in-ear headphones are often bundled with iPods and other MP3 players and can easily be placed in a pocket. A larger type of headphones have earpieces that sit on the ears but are still quite small. These headphones have an elastic frame that connects the two earpieces. This frame either sits on the head or wraps around the neck. These two types of headphones are typically the least expensive and you should consider them if you are on a budget. Some in-ear models are specially designed to absorb exterior noise.

If you are able to spend more, you could look at medium-end headphones which are larger than these very small type headphones. Each earpiece has an ear cushion that depending on the model either sits on top of your ears or wraps around your ears. The second type lowers the pressure on the ear. Therefore many people prefer this design. The next decision you'll have to make is between an open and closed headphone design. An open design essentially means that the sound from the transducer can penetrate to the outside of the headphones. It can also cross-couple into the other earpiece. An open design is perceived by some people to have a light sound quality. A closed design will prevent the audio from disturbing bystanders. A closed design also helps block out exterior noise.

The majority of today's headphones are dynamic which refers to the type of transducer that is used. Another type are static headphones. Static headphones are fairly expensive and require special headphone amplifiers.

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.

Another type of wireless headphones are digital wireless headphones. This type of headphones, such as Amphony headphones, will encode the audio prior to transmission which prevents any audio distortion during the transmission and ensures high reliability against interference. Digital wireless headphones which work at the less crowded 5.8 GHz frequency band have fewer problems with competing wireless devices than headphones working at 2.4 GHz.
