This is my first BT stereo headset so i won't be able to compare it with another one. First of all i am very happy with these. no cables at last :)I tried these with my Atom Exec and Asus F5RL laptop with built in BT. I am not an audiophile that's why this might not be useful for music enthusiasts but to me these sound really great with both devices.Indoors: with atom exec I almost have no drop outs while i have very occasional ones with the laptop especially after i just pair it and at the beginning of some songs. the later might not be device specific though.Outdoors: Drop outs are more frequent outdoors which i don't know why. But after a period it tends to stop. But these drop outs are very occasional and don't hurt much and I heard that bt620s is one of the best ones in terms of dropouts.One litle problem i had to figure out to solve was that if you forget to disconnect it from your laptop and try to use it on the way home with your phone it still thinks it's connected to the laptop and doesn't connect to the phone. you need to pair it with the laptop again and disconnect, then it can connect to other device at least it is so in my case. but nothing to worry about too much.At first it felt a bit uncomfortable to wear but after a period of time i got used to them they are all right now but not like one with a head band of course.Btw, i am listening to music in my room now through my laptop and surprisingly it didn't do any drop outs for quite a long time.To sum up, I can use all the features with my atom exec and Ausus F5RL with a very good music quality for cheap. thanks Jabra.Cheers
