Audio diterima bluetooth dengan codec:

- SBC (Sub-Band Coding) - A2DP - Standard Codec 345kbps 48khz lossy compression 256kbps umum digunakan di headset atau handphone2 lama

- aptX (Teknologi terbaru dari Qualcomm)

- Apple W1 Bluetooth (Hanya di gunakan di produk Apple & Beats)

Ada beberapa versi aptX:

aptX Standard - Transfer rate 352kbps 16bit 44khz
