Headphone & Headsets Measurement
Any headphone, any measurement
SoundCheck offers simple, fast and accurate headphone measurement. It can test any headphone or headset – no matter what the form factor, functionality, connector or additional features. It measures a full range of driver parameters via traditional analog, Bluetooth, lightning or USB connections, as well as microphone performance, active noise cancellation (ANC), L/R tracking, headset leakage, and more. SoundCheck can even evaluate the hearable and communications aspects of headsets, covering a full spectrum of hearing aid and communications tests in addition to standard headphone acoustical measurements.
Headphone & Headset Measurements
Headphone Measurement Hardware
AudioConnect 2: A low cost, high resolution, portable, laptop-powered audio interface with 2 TEDS-compatible input channels to power a range of microphones. This is our most cost-effective solution for headphone test.
AmpConnect 621: For test requirements requiring more than 2 input channels, or where an amplifier is also required, AmpConnect 621 is the 6-in, 2-out all-in-one test interface that does it all.
SoundConnect 2: If you are using an interface that does not have microphone power, this rugged and cost-effective microphone power supply will provide power for SCM, IEPE, or even 200V polarized microphones.
Bluetooth Interfaces: We offer both research grade and production line interfaces for Bluetooth headphone test
Current Monitors: Current monitors are useful for battery drain tests, for example monitoring battery consumption of ANC headphones.
Turntable: Measurement turntables for VR headset and headphone leakage measurements.
For more complex test requirements, we also offer: MEMS interfaces and amplifiers, as well as 3rd party hardware such as Head and Torso Simulators (HATS), ear couplers, headphone test fixtures and more.
Future-proofed Headphone Measurement
Headphone R&D is constantly changing, and one of the benefits of SoundCheck for headphone test is its modularity in terms of both hardware and software. Should your needs change, for example, if you manufacture conventional wired headphones and you introduce a Bluetooth product, it is a simple upgrade to add a Bluetooth interface – there is no need to buy a new test system.
The same applies to software. As headphones and headsets become more multi-functioned, if you need to add hearing aid tests such as attack and release measurements, or communications tests such as POLQA measurements, the additional modules required to do this are a low-cost add-on to your existing system and can be delivered electronically.
Examples: How do our Customers use SoundCheck for Measuring Headphones and Headsets?
These are just some of the headphone and headset measurements that our customers are making:
- 100% Production Line QC of earbuds measuring frequency response, polarity and sensitivity, as well as rub and buzz detection
- R&D evaluation of the performance of active noise cancellation with battery drain
- Incoming QC on microphones and drivers to be embedded in headset

Specialty Headphone Measurements
There are many types of headphones, each with their own specific testing needs. Expand the sections below to learn more about making measurements on Bluetooth and TWS headphones, testing active noise cancellation, VR headset leakage tests, measuring headphones to communications standards, hearables measurement and more.
Bluetooth Headphone Measurements
It’s easy to make comprehensive audio measurement on Bluetooth Headphones, headsets and hearables with SoundCheck. With the simple addition of a stand-alone Bluetooth interface to your existing test configuration, measurements can be made exactly the same way as your conventional wired headphones. Read More >
Active Noise Cancellation (ANC) Headphone Measurements
Active noise cancellation tests are a common headphone measurement. SoundCheck makes these measurements easily, and can even measure the battery drain caused by active noise cancellation. The configuration for active noise cancellation test is similar to a regular headphone test, in that you need a head and torso simulator or alternative headphone test fixture, and an audio measurement system such as SoundCheck.

Hearables testing represents the convergence of tests from headphones, microphones, telephones, telephony, hearing aids, and more. Between these, a huge number of test stimuli, algorithms, analysis options and signal paths options are necessary, not to mention many ‘useful-to-have’ features such as integrated background noise and a test configurator that makes it easy to run many iterations of a test continuously.

Measuring to Headphone Standards
Headphone standards such as IEC 60268-7 and EN-50332 cover many aspects of headphone measurement. SoundCheck is the ideal system for measuring to headphone standards as it features both flexibility and future-compatibility. Furthermore, Listen offers pre-written test sequences to measure to common headphone standards such as IEC-60268-7 and EN-50332. Read more >
