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.
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 choice 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.
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.
If you prefer freedom of movement then you should take a look at wireless headphones. Wireless headphones cut the cord. This means that you have full freedom of movement which is essential if your audio source is not mobile. One type of wireless headphones are Bluetooth headphones. These headphones can be used with cell phones and other Bluetooth-enabled devices. These headphones are typically honestly small but do not offer the same sort of audio quality as medium to high-end headphones.
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 models such as the Amphony headphones will encode the audio into data prior to transmission which makes these models the best choice in terms of sound quality and robustness against interference. Models which use the less crowded 5.8 GHz frequency band offer the lowest amount of problems with radio-frequency interference from competing devices.
