To test the battery, we use pink noise and a real-time analyzer to find the setting needed to output consistent audio peaking at 75dB(SPL) over the products.For each product, we played several sine sweeps through the earphones and logged the frequency response once we arrived at a repeatable result demonstrating the hallmarks of a good seal.You can read more about it here if you want to know more about the specifics. Specifically, we tested frequency response, isolation, and battery life to keep things simple. By using a dummy head, audio engineers can test out how audio products will perform for most people-and so do we.
