https://liesaboutparenting.com/buying-guides/cozyphones/ Though we couldn't directly find where how the cozy band was tested, but this showed us they got people to review how it worked. So I would say this is quite similar in that aspect. Though the company had people directly try this product out to test for comfort and the usage was being used. Then they wanted feedback. This is what we are looking to implement into our testing. We will be testing on people throughout the Technical High School, and at the end of the testing we will conduct a series of questions to give us feedback and data on what was working and what wasn't. https://www.sweetyhigh.com/read/pawws-silksound-headphones-headband-review-050820 The paww silk sound was tested the same way and this is why we came to the conclusion of using this method to our testing. Sort of in a review format but to give us feedback on what needs to be fixed and what doesn't.
