We tried these headphones, twice. Following its instructions with the installed app, it was challenging blue toothing (pairing) nearby devices; I made numerous, authentic attempts under steady wi-fi signals. These are superb cables that do what they purport to do very, very well. Nice headset! Comfortable ear cushions even after long hours of wearing them. I really liked the tropical styling of these head phones and they were ate the same price point as the Neons had been. I ordered these for my 2018 E400 Coupe. Sturdiness got 4 stars because I Both seem to be sturdy but I have only had the hangers for two months. Be sure to get some heel cushions for the back. A plus point in favor of the Samsung buds is that they get regular updates through the app, some performance related.
