With this headset I have indeed after 45 minutes to change the position and slightly more than 60 minutes, then uncomfortable, but I think this is more like me.
From the range I was surprised after reading some very positive reviews. About 5m by 2 plasterboard walls through is not a problem. In our house (5x10m base) I have on the same floor virtually anywhere reception. I think that here the combination of headset and mobile phone results in the effective range. I have a Nexus. 4
The sound is also quite good, although not quite as good as with my Sennheiser cable. But with Bluetooth I have heard much worse.
From another manufacturer it was at times an apparently structurally identical Amazon headset in the Bluetooth 4.0 stood. In this it should be 2.1. But maybe it's 4.0 and the results with the BT 4.0 of the Nexus 4 very good range and good sound.
Although I do not have very big head, I had to fully extend the headset. Could be with larger heads a problem.
The grip is quite good, but can not imagine that you can jog with it myself. In the event only in-ears are probably appropriate.
One star deduction that the battery lasts only 3-4 hours.
All in all I'm very happy with the headset and for the price anyway.
