We have difficulties with the range of DECT phones and wireless, especially from floor to floor in the house. Whereas the signal of this Bluetooth transmitter is so strong that again had the headphones not only one floor below, but to cross through the house at the other end stable reception - excellent, thanks to the main power supply, I might suspect. The only complaint is that the unit remembers no device applications. Headphones must be reappeared every time be "paired". Conversely worked to reconnect with the mobile phone, there was RTX-1 stored by the phone as a remote station.
