good price / quality ratio, not bad sound quality, ease of connection via Bluetooth, the small carrying case is practical, long battery life. for the negatives I first put leaflet in English (fortunately there was internet, there is an explanation for associate the two points), then we can associate only one port in the headphones and not two (computer ou_portable and not both). to wear the helmet between my tablet and headphones can do better, but still decent (distance 10m door shut from the outside of my house.)
