Bluetoothkoppelingsprocedures

Bluetooth headphones are wireless listening devices that use the Bluetooth standard to transmit audio from a source such as a smartphone, computer, or media player. They include built-in batteries, drivers, microphones, and control interfaces, and are produced in over-ear, on-ear, and in-ear styles for music, calls, and multimedia consumption.

Bluetooth technology has evolved significantly since its inception. Modern devices often support multipoint pairing, enabling connection to multiple sources simultaneously, and low-energy operation to extend battery life. Audio quality depends on codecs, with SBC as a baseline and others such as AAC, aptX, aptX HD, LDAC, and LC3 offering higher fidelity or lower latency when both ends support them.

Battery life varies widely, from around 5-8 hours with active noise cancellation to 20-40 hours in many non-ANC models. Most headphones recharge via USB-C or micro-USB. Some models provide rapid charging, or wireless charging in premium variants.

Common features include active noise cancellation, transparency or ambient modes, foldable designs, IP ratings for water resistance, and touch or physical controls. Many support multipoint pairing, voice assistant access, and detachable cables as a fallback.

When choosing Bluetooth headphones, consider fit and comfort, use case, codec compatibility, battery life, and budget. Regulatory labeling and compatibility with devices ensuring CE or FCC certifications are standard for consumer electronics in many regions.
