Headphones

Test performance

It’s no good if a product lasts for many years if it doesn’t work well in the first place. A disappointing product will soon become unloved and unwanted. For this reason, our independent lab testing forms an important part of our overall lifetime score.

Our headphones test is based on:

• Sound quality
• Comfort
• Noise cancelling (if any)
• Durability
• Sound leaking.

We get five expert testers to wear each pair of headphones and earphones and listen to a range of music genres and a podcast.

Sound quality: We assess high and low frequencies, percussion, and overall sound balance. We also note any unwanted noise and distortion. We record any differences between wireless and wired use for models with both options.

Comfort: We check how well the headphones can be adjusted for a good fit, how well they stay in place during walking, running and jumping activities, and whether there’s any restriction in the wearer’s movement.

After 30 minutes of listening, we assess how loose or tight the headphones feel, and whether they’ve become uncomfortably warm or heavy.

Noise cancelling: For models with active noise cancelling (ANC), we assess how well ambient noises are cancelled out. This includes people talking, continuous noise such as air conditioning and motorway traffic, and intermittent noises such as passing cars.

Durability: We assess the build quality of earpieces, padding, any hinges, buttons, cables and charging ports. We also drop the headphones ten times from a height of 1.8m onto a stone floor and check for any physical damage and loss in performance.

Sound leaking: We use a calibrated reference ear (a device with an acoustic input impedance resembling that of an average human ear) to accurately measure how much sound leaks out from the headphones while in use. Our expert listening panel also makes an assessment, listening for any loud or irritating noises. The sound leaking score is separate from the overall score.

Predicted reliability

It’s reasonable to expect a new set of headphones to remain fault-free for a good amount of time. Our predicted reliability won't tell you whether yours will stop working tomorrow, but it does show which brands make models that are less likely to fail early.

Brand satisfaction

Satisfaction is important – no product should be a source of buyer regret. Headphones with satisfied owners are more likely to be taken care of and therefore last longer.
