KEY TEST RESULTS

The overall Which? test score is made up of the following star ratings, all determined by our rigorous lab tests.

How we test headphones

Sound quality

Overall
Speech sound quality
Classical sound quality
Jazz sound quality
Rock sound quality

How we test sound quality

We rate sound quality using a professional panel of expert listeners with a range of ages and musical tastes. They listen to samples that cover a wide range of music and radio genres, giving a rating per recording and an overall verdict.

Microphone quality

How we test microphone quality

We test the quality of the speech picked up by the microphone on the product. We test it with and without background noise to come up with a verdict.

Comfort

How we test comfort

Our professional panel of listeners assess the comfort of the product.

Durability

How we test durability

Our lab professionals assess how well built the headphones are. We drop the products onto a stone floor from a height of 1.8 metres to test their robustness. We also put them through identical rain tests for five minutes to see if they are water resistant.

Battery life

How we test battery life

We play sounds continuously at a reasonable volume until the battery runs out. We replicate how you are likely to use the headphones, such as with noise cancelling enabled. Since wireless headphones are convenient, battery life doesn't affect our overall score for a pair of headphones (although anything particularly bad we'd make a Don't Buy).
