What is kleer technology and how does it work?

Kleer technology is a wireless audio transmission technology, which is a patent technology of SMSC company, and specializes in high-quality wireless audio transmission. Kleer technology is very expensive, so it is not common in the market, and it is currently used in many relatively high-end earphone systems.

Generally speaking, the ideal speed of Bluetooth is 320Kbps. In fact, most devices can't reach this bit rate. Kleer can transmit audio at a bit rate of 2.37 Mbps at a distance of 10 meter, and the bit rate of CD is 44. 1 kHz * 16 bits * 2 channels =1.41kloc-0/Mbps, so this technology is claimed to be lossless. This is also the main reason why high-end manufacturers such as Sennheiser do not choose Bluetooth in high-end wireless headphones.

In addition to the CD sound quality mentioned above, Kleer does not need to be paired before use, and a transmitter can play to four Kleer playback devices at the same time. Since the number of channels occupied by Kleer during transmission is less than that of Bluetooth, the power consumption of Kleer is only about110 to 1/5 of that of Bluetooth. Specific technical indicators: the frequency that Kleer can transmit is 20 Hz-20 kHz, the distortion rate is less than 0. 1%, and the transmission delay of Kleer is very small.

Kleer technology principle Kleer lossless digital transmission is a technology based on 2.4GHz frequency band, which adopts digital transmission similar to Bluetooth and 2.4G radio frequency. However, the transmission protocols are different. Kleer's goal is to ensure lossless transmission of CD-quality digital stereo audio at a reliable frequency of 2.4GHz by using the twice-sampled radio wave structure, which is the most perfect way in the same level of technology at present. Because this technology is unique to Kleer Semiconductor Company and is in the patent protection stage, its detailed working principle has not been disclosed yet.
