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. Rather than the test signal being directly transmitted to the headphones via a cable, it is sent to the Bluetooth interface and transmitted to the headphones. Our Bluetooth interfaces are fully controlled by SoundCheck, therefore are easily used in test sequences. The SoundCheck software itself features advanced post-processing tools resampling and frequency shift to overcome the Bluetooth time delay and precisely synchronize the stimulus and response waveforms prior to analysis. This makes it easy to compare wired and Bluetooth measurements, as well as measure Bluetooth headset microphones, analyze Bluetooth dropout, compare measurements with different Bluetooth protocols and more.

 

Example configuration for Bluetooth Headphone Test:

This short video demonstrates how easy it is to add Bluetooth headphone measurements to your test system:

 

We also offer a much more in-depth demonstration of Bluetooth headphone testing in this recorded seminar, along with a detailed comparison of our Bluetooth interfaces.

 

To get our SoundCheck users up and running quickly with Bluetooth measurements, we offer a free Bluetooth headphone test sequence which tests the send and receive performance of a stereo Bluetooth headset with a built-in microphone using a mixture of analog and digital channels. This sequence may be used as-is, or can be used as a starting point for your own test development and customized to meet your needs. Naturally Bluetooth measurements can be combined with other specific headphone measurements, such as ANC measurement by simply adding the Bluetooth interface to the test configuration, and inserting the appropriate steps in the test sequence.
