They come in the (now common) charging case and they fit snugly and charging is quick once Bluetooth was activated on my devices pairing was immediate and stable/reliable. I love the concept of these ear phones. Truly wireless. The buds Bluetooth with each other then with your device to provide totally wireless music.The sound quality is OK but not great. Noise isolation is OK but again not great. Battery life is also not brilliant with about 2 hours between charges. Unit comes with a charging unit that the buds clip into. This holds enough charge for several charges. sound quality and battery life are not quite as good as wired buds.They have the usual touch pad controls, which I found, end up pressing when I'm getting them in and out. The controls are quite responsive though. I found them pretty comfortable to wear even for long durations, they stayed in my ears nicely even when walking, jogging and jumping., however I did find that people with smaller or waxy ears struggled to to keep them on.The problem is that spoken voices are a really a bit muddy and muted and I found I was putting the volume up so far that my phone's 'health of your ear' monitoring thingy was constantly complaining - so while the music reproduction wasn't too bad, voice calls and listening to audiobooks wasn't a brilliant experience.If you're into your music then stay away from these - compared to a premium set of earbuds they're poor and make music pretty bland. Would be okay for sitting listening to YouTube videos or audio books if they were a bit cheaper.
