Bluetooth is a short-range wireless technology that allows you to connect headphones or portable speakers, a stereo system or a soundbar to your smartphone or laptop. For a certain version to work, both devices must support it. The versions differ in data transfer speed, power consumption, securing data transfer, anti-interference ability and range of connection.

To take advantage of a particular codec it must be supported by both devices

ANC is used to reduce the external noise while listening

No higher than 32 Ohms for smartphone headphones. When using a good player or amplifier, it can be up to 100 Ohms. For stationary models you should coordinate the impedance with the amplifier power

More sensitive headphones will play louder than headphones with less sensitivity (with the same signal level and resistance)

Most of the headphones are dynamic but there are electrostatic, isodynamic, etc.

Open (with no insulation) or closed (passive noise insulation) or semi-open (intermediate version). Open headphones sound more airy and provide a wide stage, closed ones provide noise isolation and amplify low frequencies.

The opportunity to disconnect the standard headphone cable makes it possible to experiment with different wires.

It allows you to fold the headphones so that they take less space in your bag
