WiFi and Bluetooth are off-the-shelf wireless technology. They are working on 2.4GHz ISM band which is open for all radio devices. Due to more and more devices use 2.4GHz band, they have serious interference. It is not an appropriate technology for audio streaming.
With our 20+ year wireless experience, we reform DECT protocol for HiFi audio application, adding audio mandatory elements, completely resolve wireless audio problem. We have put key HiFi audio criteria into DECT audio protocol :
The first generation DECT audio launched at 2016. After 5 years work in 2021, DECT audio technology elavate to second generation.
WiFi and WiSA never are battery operation, only DECT wireless speaker can be powered by battery. A full charge of ONEmini speaker has 100 hours play time !
By DECT technology, we have the World’s only TRUE wireless surround, without speaker cable and power cord. The true wireless 5.1 technology bring us award winning 2016 : CES Innovation Award and DECT Innovation Award.
DECT is low radiation device, only 1/10 of WiFi and 1/20 of WiSA, put your body in safe place.
DECT is not high data rate protocol, it can guarantee a constant data rate for lossless audio streaming. Even DECT is working at 1/10 power of WiFi, it can have longer range and better penetration.
Secondary re-transmission degraded the sound quality
Bluetooth stereo speakers run on master and slave configuration.
Master speaker is primary channel receive compressed L+R audio. Master speaker decompress L+R audio, retrieve R audio, compress R audio and re-transmit to slave speaker.
Slave speaker R audio has serious distortion and time error. You can only listen L channel and R channel sound on master speaker and slave speaker, but you never experience sound stage and sound imaging.
