I rate them for the price I brought both for 100 euros from abroad. They have all possible cases for installation, you won't miss anything!!! So, easy installation. On the road, you hear them crystal clear. The signal reception for the radio is quite good, I would say, as well as the communication with the passenger!! Sometimes the connection is simple, other times it might take a little longer, but they will always connect. In light drizzle, no problem!!! The battery life is enough for a trip of around eight hours. Quick charging, but be careful, the plug might need a little fixing with a knife to fit properly. At 255 euros, no.
