A question that pops up when considering to purchase headphones is: “What type should I get?”
-Over Ear (Circumaural)-
The earcups on over ear headphones, as the name suggests, rests over the ear. They are sometimes called full size headphones, and most of the professional models feature this design. They are have the ability to isolate noise better.
On ear headphones rest on your ears, instead of going over them. This makes the headphone smaller and more compact, however it may cause slight discomfort for users, depending on the model and the brand.
A headset is basically a headphone that features a built in microphone. The mic may be retractable, or it may be fixed. These products are most commonly used for Skype/video conferencing programs, and other pieces of software that require your voice to be heard.
An iconic earbud would be the white Apple one that is included in all iDevices. They are mostly cheap and uncomfortable, however some users prefer it to more complex ones because they are more convenient to put on. They hardly cancel noise, and you may damage your ears if you turn up the volume of the music to block out unwanted exterior sounds.
-In Ear Headphones (In Ear Monitors)-
Unlike earbuds, IEMs are inserted into the ear canal instead of hanging on the outer ear rim. They can range from a low to high price. IEMs are portable, and are a good substitute for on or over ear headphones. In ear headphones feature detachable silicon or rubber ear tips. Custom IEMs are often used by artists, music producers and bands to clearly hear the music around them. Those tend to be priced at over $1000.
