In Ear Headphones

Other names- Canalphones, In-Ear Monitors, IEM's

In ear headphones are earphones that go directly into the ear canal.  They are great for reducing outside noise.  They are generally made of silicone rubber, elastomer, or foam.  This type of headphone is great for anyone that moves around- they are lightweight, easily portable, and stay in the ear with a lot of movement.  They tend to be more expensive than regular earphones.  The two main types of In Ear headphones are universal (standard issued by a manufacturer to fit the average ear) and custom (fitted specifically to the listener’s ear canals by the manufacturer).
