Other scores don’t count towards the overall score.

For our test, we get 5 expert testers to wear each pair of headphones for an extended period while listening to a range of content from various audio sources. Each set’s sound quality was also tested using a reference ear, a device with an acoustic input impedance resembling that of an average human ear. This was also done for noise-cancelling if applicable. The scores from the testers and reference ear are then averaged into the final sound quality score.

The same 5 testers allocate the comfort score. Finding the headphone type that’s most comfortable for you can take time, because everyone’s ears are different. Earbuds often come with different-sized rubber nibs to help fit into your ear. Over-ear headphones tend to be bigger and heavier, so you may need to adjust the headband to get the fit right.
