usually our bluetooth headset choose with CSR Chips, ISSC Chips, JR chips.
and now let me tell you what is different from different chips.
1. CSR chips, Is import from UK, the sould quality is clear, clean, stereo.
Average power consumption only 15mA/Hour, so same battery can use longer time .
and usually we use CSR8635 Bluetooth 4.1 chips, it can connect with two phones at the same time.
but it Average power consumption has about 30mA/hour, some battery like CSR Can work with 6hours, they only can works with out 3hours.
and it only can connect with one phone, not two phones at the same time.
3.ISSC chips, It with Better quality than JR Chips, Also with Bluetooth 4.1 Technology,stereo sound quality.
