Range

Range of wireless-capable headphones (see "Connection type").

When evaluating the range, it should be taken into account that this parameter is rather conditional and the actual range may differ slightly from the claimed one (usually in a smaller direction). So, when connecting via a radio channel, the range is indicated for perfect conditions — without interference and obstacles in the signal path. For Bluetooth models, the range also depends on the power of the Bluetooth module in the device to which the “ears” are connected. And the effectiveness of the IR channel may be reduced in hot weather or in bright sunlight. So when choosing according to this indicator, it's ok to take a certain margin.

On the other hand, there are two points worth noting. Firstly, in general, the specified range accurately describes the capabilities of the headphones, and it is quite possible to evaluate and compare different models with each other. Secondly, even in the most modest wireless “ears”, the communication range is about 8–10 m, 11–20 m is considered an average, and a fairly large number of devices can operate at distances of tens and even hundreds of metres. So paying attention to the range makes sense mainly in cases where you plan to move away from the signal source at a considerable distance — from 5 m or more — or listen to sound through walls.

NFC

NFC is a short-range wireless communication technology (up to 10 cm). One of the most popular ways to use this feature on your headphones is to automatically connect via Bluetooth (see "Connecting"). When these Bluetooth “ears” are brought near an NFC-compatible signal source (for example, a smartphone), the devices automatically recognize each other, configure the connection settings, and the user only has to confirm the connection. In addition, other options for using this technology may be provided — for example, automatic playback start when you bring headphones to the player.
