Qcc514x is for high-end market and qcc304x is for middle and low-end market. Both of them support active noise reduction and voice assistant functions.

Both chips use Qualcomm's TrueWireless Mirroring technology, which allows one-sided headphones to connect to the phone via Bluetooth while maintaining a connection to the other.

The two chips use Qualcomm's hybrid ANC technology, which integrates the active noise reduction function. According to foreign media, the relatively cheap wireless headset products using these chips can also have the active noise reduction function.

The main difference between qcc514x and qcc304x lies in the integration of voice assistant. Qcc514x supports wake-up word wake-up voice assistant, and qcc304x only provides key wake-up.

Foreign media said that at present, it is not known when Qualcomm will bring these two products to the market.
