How we test tv/film overall sound quality

This is the important sound quality star ratings section to consider for TV headphones (the other section is our usual headphones listening material for music and radio). This is the ratings from our professional listening panel for a series of TV and film recordings (similar to our sound bars test). Cinema sound quality focusses on sound effects such as the backing soundtrack and explosions. TV/film speech sound quality ensures TV and film narration and dialogue are as clear as possible.

How we test sound quality

We rate sound quality using a professional panel of five expert listeners with a range of ages and musical tastes. They listen to nine recordings for each pair of headphones, which cover a wide range of music and radio genres, giving a rating per recording and an overall verdict (not an average).

How we test latency

The speed of the headphones' connection. This is important for video to ensure the picture and sound match up exactly.

How we test acoustic seal to your surroundings

Our expert listening panel and lab professionals assess how well the headphones prevent sound leaking out to their surroundings. This is done in two ways: firstly, we ask our five member expert listening panel to note how much sound they can hear while the headphones are playing next to them. Second, we measure the sound leakage objectively using an external microphone. It's particularly important to choose headphones with a good acoustic seal for travelling, to avoid annoying your fellow passengers.

How we test comfort

Each of the five members of our professional listening panel, who have a range of ages and ear sizes, gives a rating for how comfortable they find the headphones to wear, and we take an average.

How we test durability

Our lab professionals assess for how well built the headphones are. For wired pairs, the focus is on the strength of the joint between the headphones and the cable, as this is where many cheaper wired headphones fail. For wireless pairs, the focus is on the strength of any moveable joints. We made our durability test for wireless headphones more rigorous from May 2018, so the star ratings for wireless headphones from then onwards aren't comparable to wireless headphones tested before.
