Electrostatic transduction, the condenser microphone’s inverse, delivers the highest headphone and speaker quality.

Evidence

Another technique used in the highest-quality headphones is the electrostatic principle, which is the inverse of the condenser microphone working principle described in the next section. The electrostatic principle is sometimes also used to make high-quality loudspeakers, especially at mid-to-high frequencies. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 477
