How we test sound quality

We make a series of calls from each phone while an expert checks the sound quality at both ends of the line. Our experts also listen to calls on the speakerphone and assess the sound quality of incoming and outgoing messages left on the answering machine.

How we test ease of use

Ergonomic experts assess how easy it is to set up the phone, add contacts to the phone book and make and receive calls. We rate the general handling, including whether the buttons are well spaced and the display easy to read, and also assess how simple it is to operate the answering machine.

How we test phone range

We check the range of each cordless phone by measuring the call quality on different floors within our laboratory and through steel and brick walls. We also note whether the phone will you if the signal is getting too weak before cutting out.

How we test features

We check for the presence of useful features such as speed dial keys and a speakerphone as well as looking to see if the phone is hearing aid compatible. For models with an answering machine we also award extra marks to those that have large memories and can store lots of messages.

How we test call blocking

We test each model's capabilities by making calls to it from various types of phone numbers, to verify that the blocking is working as well as it should.
