Bluetooth support is handy when travelling and may also allow you to take a mobile call using an onboard mic.

Takes phone calls View more details.

Whether the models on test can take a phone call, either through wireless Bluetooth or via a cable connection.

Digital assistant support View more details.

Do the headphones have built-in support for a digital assistant such as Google Assistant or Alexa? Some models use their microphones to activate the assistant on your phone but this is not the same as having the assistant built into the headphones. Models without this feature get a red cross. This data is a recent addition to the test which is why older models are listed as "Not tested".

Not tested
