The term Wireless Range describes headphones that offer a cable-free listening experience. They receive and reproduce audio over a wireless network, typically via Bluetooth but also through Radio Frequencies for home theater headphones.
Wireless headphones offer a lot of range from the audio source. This means you can listen to your music or movie while having the freedom to move around in your environment and even continue listening in another room. They also free you from the hassle of cable management, preventing the headphones from being yanked off your head, because the audio cable got hooked or tangled on something. A good wireless headphone should be easy to pair with your devices, have a decent wireless range and maintain a strong and stable connection, without much latency, even when obstructed by walls.
Our Wireless Range test measures the direct line of sight and obstructed range that these headphones provide, as well as the type or version of the wireless connection. We also check how easy it is to pair with regular and NFC-enabled mobile devices.

Playing audio over a wireless network allows the listener to not be limited by the length of a cable. For example, you could leave your Bluetooth-enabled phone to charge in another room and still listen to your music or take calls, while walking about in your home or office. It's even more important for the listeners that use their headphones with a source that's difficult to move, like a PC or TV. However, depending on your listening habits and headphone choice this might not be a significant feature for you.
We measure the range that the wireless headphones are capable of, when in direct line of sight and when the Bluetooth source is obstructed. We also take into account, the simplicity of the pairing procedure.
The type of wireless connection established between the audio source and the headphones. This is typically done via Bluetooth, but some home theater headphones have a stand that broadcast a specific radio frequency, which the headphones are tuned to. Bluetooth versions also vary from headphone to headphone and come with a suite of features that improve the data rate of transmission, battery life or adds additional codecs to reduces lag and latency.
This is the headphones' range when the Bluetooth source is obstructed by walls and has been placed in another room. We test for this by connecting the headphones to a Bluetooth 4.2 enabled phone and place the phone in the furthest of the four rooms we currently have in our office. We then evaluate the distance with a measuring wheel, going from room to room, until the wireless connection is too weak to reliably, transmit audio without any drops.
This measurement is done three times and then averaged to obtain the obstructed range. However, although the results are consistent in our office it may vary depending on how many walls or obstructions the Bluetooth source will have to go through in your home or office layout.
This is the headphones' range when in direct line of sight with the Bluetooth source. We test for this by connecting the headphones to the same Bluetooth 4.2 enabled phone in a large open area. We then evaluate the distance, with the measuring wheel, until the wireless connection is too weak to reliably transmit audio without any drops.
This distance is also measured three times and then averaged to obtain the line of sight range. However, unless you are often in a large and open environment, this range won't be as relevant for you and is therefore attributed a much lower percentage of the wireless score.
NFC is used to quickly transmit data wirelessly. This technology is often used to efficiently transmit pairing protocols and connect an NFC-enabled device to your headphones without too much hassle.
However, most headphones still use the typical hold-to-pair procedure that can get a little tedious when often switching between Bluetooth devices. We, therefore, attribute a small percentage to the headphones that use the much simpler NFC technology over the typical procedure.

Our Wireless range test measures the reach and reliability of a headphones' wireless connection. These headphones typically transmit data via Bluetooth or radio frequencies and provide a cable-free listening experience that gives listeners more freedom and mobility. This means you can listen to your music, movies or podcasts without needing to move the audio source or be in the same room. We test the wireless range when in direct line of sight and when the Bluetooth source is obstructed. We also evaluate how easy the headphones are to pair with mobile devices. However, depending on your listening habits and headphone choice this may not be a significant feature for you.
