Using Wi-Fi on the new X7 Mark II is a much better experience than on the original model, due to support of Wi-Fi on both the 2.4GHz and 5GHz frequency bands. This allows for more stable, stronger signal reception strength and faster speeds. In addition, FiiO has paid special attention to the internal design to ensure that all of your wireless signals, whether it be Wi-Fi, Bluetooth, etc., will not suffer from outside electromagnetic interference. All of this means that compared to the first generation, the new X7 is much better equipped to deal with EMI.
