As was mentioned, Bluetooth is the standard wireless protocol when it comes to this technology. But, there are numerous versions out there and the latest (as of this writing) is Bluetooth 5.1. Yet, version 5.0 made the biggest leaps and is the more noteworthy of the two. Knowing the upgrades may make you think twice about getting noise-canceling headphones that still use a fourth version of the wireless protocol. Most specifically, Bluetooth 5.0 took leaps in its speed and range. Its speed jumped up to two Mbps while the range went from 30 to 260 feet (which is incredible).
