Definition

The power necessary to bring the IEM to the specified volume, typically measured at 1 kHz.

The transducers.

In-Ear Monitor: A miniature headphone small enough to fit partially into the end of the ear canal, and typically light enough to stay in place purely by friction and seal.Custom eartips are available for some models of universal IEMs, effectively making them a hybrid between universal and custom -- at least until the custom tip is replaced with a conventional one again.IEMs because of their inherently bespoke nature; They tend to be larger and are often able to accommodate more drivers, electronics, or driver tubing, ideally to provide better sound quality.The input impedance of the IEM, a phase-dependent function of electrical resistance and reactance, typically measured at 1 kHz.

The mechanisms that contain drivers. Some receivers, like the TFWK, DTEC, or Sonion 3300, contain more than one driver.attached to the IEM's cable exit to help keep the cable shaped to the profile of the ear. Some IEMs are designed so that the cable can be used either way.Vented IEMs will have very little isolation. Some IEMs, such as the customs made by Alien Ears, have optional adjustable ambient noise ports.
