The A2DP profile works by compressing audio data and sending it over a Bluetooth connection. Unlike the "Hands-Free Profile" (HFP) which is designed for low-bitrate voice calls, A2DP is built specifically for multimedia.

Ensure there are no large file transfers happening over Bluetooth, as this limits A2DP bandwidth.

| | Cons | | :--- | :--- | | Native Integration: No need for 3rd party drivers on Win 10/11. | Outdated Codecs: Strictly SBC; no native AAC, aptX, or LDAC. | | Ease of Use: Pairing and connecting are streamlined and fast. | High Latency: Not suitable for gaming or precise video editing. | | Bi-Directional: Can act as both Source (headphones) and Sink (speakers). | HFP Issues: Microphone usage degrades audio quality drastically. | | Stability: Generally robust connection once established. | Reconnection Bugs: Resume-from-sleep reconnections can be buggy. |
