Note: This article is relevant for all models of the REAL BLUE/BLUE NC.
The headset function of the REAL BLUE NC can be used if the paired device also supports this function. For this, the paired device must be able to both send and receive audio signals via Bluetooth. Unfortunately, many older devices such as TVs, laptops, PCs, etc. do not support this.
If necessary, ask the manufacturer of the connected device for more details.
