Since the release of the BTA30 Pro, FiiO has been relentlessly trying to enable LDAC on more devices. Despite facing challenges like high costs and lack of original manufacturer support, FiiOs determination paid off and they have now achieved a breakthrough. In contrast to the CSR8675, the LDAC transmission supported by the BT11 not only boasts higher computational power but also utilizes the next-generation LE Audio technology and even supports aptX Lossless. These features come together to create a high-end Bluetooth audio experience that delivers exceptional wireless sound quality.

While the BT11 is only about the size of a button, it is equipped with Qualcomm’s flagship Bluetooth chip, the QCC5181.
