Cai Yi, President of Suzhou Pairlink Network Technology: 「During the development of the BLE and BT Audio solutions we selected, the hardware operated stably, the software protocol stack was comprehensive, and the interfaces were flexibly open, allowing us to successfully carry out innovative application development. The collaboration between Realtek and Pairlink has been very smooth, with effective synergy and significant results. 」

Recently, the amount of Bluetooth devices that support A2DP source/ HFP capability has grown dramatically. Nowadays, most users might have multiple devices, such as mobile phones, tablets, soundbars, TV sets, game consoles, etc. (Please refer to Figure 1 / Figure 2.) Simultaneously, the TWS earbud is now the most popular audio/voice sink device. If solution vendors can provide an easier way of creating/maintaining connections and smoothly switching between source devices, it will end up helping users significantly. Thus, Multilink, called Multi-connection, became a mandatory capability in Earbud.
