How does Kleer substantiate its claim of 10 times the battery life of a comparable Bluetooth stereo audio solution?
Measurements on Bluetooth 1.2 and 2.0 stereo audio headphones available on the market today show power consumption of approximately 150mW. Kleer’s power consumption is less than 30mW which is a factor of 5 times less. However, this is not an apples-to-apples comparison because Kleer is carrying 3-4 times the data rate. Bluetooth uses lossy compression to reduce the audio data rate to 350Kb/s whereas Kleer carries the full 1.4112Mb/s. This is why Kleer’s audio quality is so much higher. Kleer estimates that a Bluetooth solution carrying 1.4Mb/s streaming audio would consume at least 300-400mW and this is the basis of our claim.
