Headphone, Earphone, & Headset Testing
Measuring and characterizing the audio quality of headphones, earbuds, and headsets present unique challenges to both the design engineer in an R&D lab and the test engineer on a manufacturing line. Learn what it takes to select, setup, and use the right test solutions.

Headphone & Earphone Test Solutions
The difference between headphones and earphones is straightforward. Earphones (unsealed or sealed) fit into the ear (e.g. supra-concha which rest upon the ridges of the concha cavity vs intra-concha which rest within the concha cavity). Headphones fit either on (circumaural) or over-the-ear (supra-aural). The solutions available for testing these devices depend on the engineer’s performance and budget constraints.
