It is this confusion was the reason for my question to real users, "Does anyone notice a difference in the autonomy of the ear, depending on the version of bluetooth phone?"
This difference is and that there is a technical explanation: data headphones are built on qualcomm QCC3020 chip, open specifications and that we vidim-
Audio Technology: Qualcomm TrueWireless в„ў Stereo technology, Qualcomm TrueWireless в„ў Stereo Plus technology, QualcommВ® Broadcast Audio technology, QualcommВ® aptX в„ў audio technology, QualcommВ® cVc в„ў audio technology
Here, the energy savings is the technology Qualcomm TrueWireless в„ў Stereo technology / Qualcomm TrueWireless в„ў Stereo Plus technology, what it means:
"TrueWireless Stereo introduces a number of important changes in sound processing. The technology allows the headset to automatically switch between the primary (receiving data from your phone and transfer them to another earphone) and auxiliary (getting data from another earphone) roles. This helps to balance the energy consumption and, as a consequently, increase the battery life.
Qualcomm also unveiled a new TrueWireless Stereo Plus mode, which allows the phone to connect directly to both earphones. This simplifies the complex chain that is usually one earphone connects to your phone and then separately connected to other headphones. According to the company, the new mode of the pairing of devices faster and with sound transmission delay is reduced. "
Accordingly, this technology will work only if: Bluetooth 5.0 Bluetooth Low Energy sensor hub / Dual-mode Bluetooth, that, in fact, confirmed by many users, who conducted tests with Bluetooth 5.0 and Bluetooth 4.0.
By the way, waiting for these headphones (already sorted), so that soon began to drink a small report, if you're interested.
