Excellent Bluetooth Connection Performance Using Qualcomm CSR8645 Bluetooth chip
Qualcomm CSR8645 is renowned for its excellent connection stability, low power connection technology, and high-quality audio transmission. It is the representative of Bluetooth wireless connection technology on the market, with 3 seconds of fast connection, excellent connection speed, and more robust signal anti-interference ability.
Bluetooth 4.2 + EDR Bluetooth Enhanced Rate
Bluetooth 4.2 with EDR significantly improved the data transmission rate. It's three times as better as common Bluetooth, and let Bluetooth transmit faster, transmit more steadily, higher efficiency, and consume less power.
ACC-LC Advanced Coding Technology Compatible with Apple's lossless transmission mode
AAC (Advanced Audio Coding) encoding format is better than MP3, better sound quality, smaller files, faster transmission.
Industrial Grade Ceramic Antenna The sensitivity of Bluetooth reception is better
With an industrial-grade ceramic antenna, the transmission is more stable, and gain is higher. The antenna's size was decreased, but sensitivity has increased, and the noise level of the receiving circuit has decreased by 1/3. Bluetooth transmission is now more reliable.
