This technology is optimized for Bluetooth transmission, and high-quality sound is achieved by reviewing the waveform correction processing in consideration of the characteristics of the codec and optimizing the parameters used for each codec. ■ Reproduces smooth sound with a wide range through waveform correction processing optimized for Bluetooth transmission To regenerate the musical information lost by compression processing, the processing range is extended to a lower frequency band than before to perform waveform processing. By performing highly accurate waveform correction processing, smooth sound with a wide range is reproduced. 【Product Specifications】 ■ Type: Dynamic type ■ Communication method: Bluetooth standard Ver.4.2 ■ Output/Maximum communication distance: Bluetooth standard Power Class2/approx. 10m ■ Supported Bluetooth profiles: A2DP/AVRCP/HFP/HSP ■ Supported codecs: SBC/AAC/Qualcomm aptX audio ■ Supported content protection: SCMS-T method ■ Power supply: DC3.7V, built-in lithium polymer rechargeable battery ■ Battery life: Approximately 7 hours ■ Charging time: Approximately 2 hours ■ Weight: Approximately 33g
