I agree with the previous comment: beautiful object, beautiful materials, heavy, nice ... But what price for it! Of course the sound is good, especially with a good helmet. The Bluetooth tends to limit the quality. And it is a subject of more manageable ... The interface is not great, and although android I have not found a way to install applications. Deezer for example. Overall I do not see what use the wifi. If it's just for the updates ... blah ... The Qobuz access is useless. No streaming for example. You have to buy the securities. I struggled to manage tracks and download them from a Windows PC or a Mac 8.1. Still lacks some things (titles, interpreters and CD cover). FINALLY IS UNACCEPTABLE AND IT: NOTICE IN FRENCH AND NO NO INFO ON THE WEBSITE. In short: too expensive for the services offered.
