Solution required for testing headset.

Question

We are looking for a solution to test the sound output of the earphones. Our testing requirement is that we need to identify defective pieces. Few defective earphones have sound level or sound quality imbalance between the L and R speaker of the earphones which needs to be rejected. Few defective earphones have intrinsically poor sound quality output.

Answer 1

I've found a website for you that tests various specs which can be found only on headphones. I've used my headphone and tested the following:

• Frequency Response
• Spectral Flatness and Earbud Insert Test
• Dynamic Range
• Quality
• Driver Matching
• Wiring
• Binaural Test
• Music Playback
