Poolkõrvasisesed

Poolkõrvasisesed refers to a type of in-ear or semi-in-ear earphone where the earpiece rests partially within the ear canal but does not create a complete seal. This design is distinct from fully in-ear (or in-ear monitor) earphones that insert deeply into the ear canal and from on-ear or over-ear headphones that rest on or around the outer ear.

The construction of poolkõrvasisesed earphones typically involves a nozzle that enters the ear canal to a shallow depth, often accompanied by a soft silicone tip or a mesh covering. This allows for some ambient sound to enter, which can be advantageous for situational awareness. They are generally smaller and lighter than fully in-ear models, making them comfortable for extended wear for some users.

The sound profile of poolkõrvasisesed earphones can vary, but due to the less intrusive fit, they may offer a wider soundstage compared to deeply inserted earphones. However, the passive noise isolation is usually lower, meaning they are less effective at blocking out external noise. This can be a drawback in noisy environments.

Common examples of poolkõrvasisesed earphones include many earbuds that come bundled with smartphones and some popular consumer audio devices. They are often chosen for their comfort, ease of use, and ability to provide a balance between audio immersion and awareness of one's surroundings. Their popularity stems from a balance of comfort, moderate sound quality, and the ability to maintain some connection to the environment.
