Accessorising is the trend especially when it comes to your desktop/laptops/music systems, etc. Plentiful brands are exploring this segment of headphones, focusing on different applications. So, if users know exactly what for they'll be using headphones, it becomes that much easier to pick the right kind.

Circum-aural
The circum-aural have the best sound quality. Their structure is their main feature – a huge cup that encompasses the whole ear; the rim has a soft padding. The driver size is about 1.5-2 inches, and they are usually high in impedance, thus giving louder output volumes.

There are two types of circum-aural headphones, closed back and open back. The closed back ones are totally solid all through the 'cup' that encloses the speaker, while open back headphones have a grille.

These headphones are almost always attached over the head via an adjustable headband. These do get heavy sometimes, especially with the larger closed back models.

Supra-aural
The supra-aural version of headphones are commonly known as 'over the ear' headphones. These headphones perch themselves on top of the pinna, and are thus, lighter and smaller and look less obtrusive. They are covered with foam over the whole driver surface. Other than this, the supra-aural versions when compared to the circum-aural have a little less in clarity and tightness in their sound reproduction. Supra-aural are constructed with a traditional headband over the head. Nowadays, you can find them attached to clips that fit around the ear, so they prove lighter without the headband. Another style is when the headband is bent to fit around the back of the head, thus keeping hair intact.

There are also some specialised circum-aural/supra-aural types of headphones like noise canceling ones. These have a special circuitry that needs to be switched on, after which out coming noise is switched off, and you feel like you are suspended in a state of deaf doubt, as you can’t really hear your own voice.

A headset is a combination of supra-aural (or circum-aural) headphones along with a microphone coming out of the left ear piece. This is common in call centers and are used primarily for internet communication and gaming, where speaking is required.
