I bought this about 45 days ago and have been waiting to write a review. I bought a brown universal junction box. The set includes headphones in a charging case, a protective case to store the device, a USB adapter that sits securely in the case, a charging cable and a soft cushion in 3 sizes to fit the ear canal. I didn't have any connection issues - I just plugged the USB into my government laptop and it worked straight away with both MS Teams and my softphone. The sound quality is normal - no problems. When I asked my colleagues about their sound quality, they said it was perfect. I've used them for up to 1 hour 45 minutes with no battery issues. I charge them every night so I start with a full charge every morning. I put it back in the charging case between calls. I think my 8 hour work day - sometimes up to 6 hours total - is not a problem. I will say my ears start to hurt after 1 hour and 30 minutes, but that's no different than using a traditional on-ear headset. The only complaint I have (and not enough to deduct a star in my opinion) is that the case is quite difficult to open - almost inconvenient. Overall I am happy with my purchase and would recommend them for remote work. (Note that my Apple AirPods are generally more convenient, but they don't connect to my government laptop - I needed a USB dongle).
