  • Deep-bass capability
  • Full-range designs with one driver per side
  • Wide material and acoustic-tuning choices
 Full-range, or bass in hybrids
BassMidsTreble

A dynamic driver can handle the whole mix. Multi-driver IEMs often assign it the lows.

  • Compact receiver packaging
  • High efficiency in suitable designs
  • Dedicated bass, midrange and tweeter options
 Band-specific or full-range
BassMidsTreble

The chosen receiver determines its job. All-BA arrays can cover bass through treble.

 Full-range, or a specialist band
BassMidsTreble

A full-size planar can cover the whole spectrum. A smaller element may serve only part of a hybrid.

  • Low moving-mass design
  • Dedicated upper-treble extension
  • Complements separate bass and mid drivers
 Treble / ultra-treble in IEMs
BassMidsTreble

Commonly used as a tweeter in multi-driver IEMs. Full-size electrostatic headphones are a different system.

Inside the technology
Configurations

Technology is not
driver count.

Read the construction and the configuration together. A shared label does not tell you how every band is handled or how the finished product is tuned.

  1. Single Driver

    One active driver per side. This is not the same as one technology spread across several drivers.

    Single dynamic designs Single planar designs
    For example

  2. One technology, several drivers

    An all-BA array can use multiple drivers and still belong to a single technology family.

    Explore all-BA arrays
    For example

  3. Hybrid

    Two technology families in one earpiece, most often a dynamic driver for bass with balanced armatures or a planar above it.

    Explore DD hybrids Explore planar hybrids
    For example

  4. Tribrid

    Three technology families, such as dynamic, balanced armature and electrostatic. The product specification gives the actual driver count.

    Explore EST tribrids Explore planar tribrids
    For example

  5. Quadbrid

    Four technology families in one shell, for example dynamic, balanced armature, planar and piezoelectric.

    Explore piezo quadbrids Explore bone conduction quadbrids
    For example

  6. Not every tag is another driver

    Piezoelectric and bone conduction can describe one physical component. Do not add tags together to calculate driver count.

    Understand piezoelectric Understand bone conduction
    For example
