Auf die App und wie die Klanganpassung abläuft, gehe ich im Abschnitt „App“ ausführlicher ein. Bin sehr zufrieden und Lieferung war auch schnell. For being Skechers, I Thought they would have a more cushy , softer feel . Will discard it. a smartphone which allows you to control the the pairing process in a more user friendly way. I mean it really does help boost the fm radio but if you are in a parking garage or somewhere underground it will get fuzzy I know this is for marine purposes so I cant really complain. Highly suggest these to anyone who lifts . Great foot cushion & support. Great for fishing or any other activity where your feet may become wet. like I said decent for what it is, looks pretty nice too, I just didnt account for how stationary I was able to make a wheeled rack.
