Overview of bluetooth headphonesadmin
Put an end to the cable clutter and give yourself freedom of movement with a pair of Bluetooth headphones! These models connect wirelessly to the player and can be ideally combined with modern electronics: all current smartphones supply music via Bluetooth, as do tablets, many notebooks and desktop computers. Even newer televisions send the TV sound to suitable headphones via Bluetooth.
Pay attention to the technical details when buying
In contrast to older wireless headphones, interference with other devices is ruled out with Bluetooth wireless technology. And the sound quality does not have to suffer from the radio transmission either. Depending on the Bluetooth device class, the theoretical range can be between 10 and 100 meters. Players and headphones ensure communication via a so-called profile ( A2DP ). Among other things, this profile defines which codec is used during transmission. In addition to the obligatory SBC , many manufacturers are increasingly using aptX . This codec is characterized by high sound quality at low transmission rates and very low latency.
Bluetooth is constantly being improved and has already had a few iterations from version 1.0 to 5.x. The improvements resulted in higher transmission speeds, continuous improvements in security and lower power consumption.
Also suitable for telephoning
Most Bluetooth handsets are also suitable for making phone calls. You also need a built-in microphone and control buttons, for example for answering calls and volume control. The in-ear variants have the hands-free microphone and the control buttons on the connecting cable between the left and right plug. The bracket models have a microphone and buttons in the ear cups. Another profile is required for these remote control elements to speak with the player: AVRCP.
The biggest disadvantage of the wireless headphones: These headphones need electricity for wireless reception. However, the integrated batteries usually only last five to eight hours and then have to be recharged via a USB port. In the event of a power emergency, many headband models can also be connected to a headphone output using a cable.
