I have the headset for a few days now in operation. The sound and the recording quality is excellent. It is very comfortable to wear, it does not press and even after several hours it will not be uncomfortable. The battery life is significantly longer than the specified six hours - it holds about 8 hours. The charging time is about 2 hours in order to load during use but takes a long time. I was always a friend of head straps, because I did not want to be disturbed by the neckband even when leaning back. As the little brother of the H760 Logitech was with his headband so uncomfortable to wear but, I thought that I nevertheless times a headset with neckband most - and have not been disappointed. Really liked me also use the controls on the headset itself - you can use all popular multimedia application also from the sofa. The only drawback is the processing - the headset is really pure plastic. What I find very unfortunate, since one of Logitech really high quality is used. Ultimately it deliver a star. Nevertheless, a strong buy recommendation!
Addendum: Now, after several months of intensive use, the headset is broken. When placing the strap is broken apart in the middle. What, in addition to the permanent use of my hand, certainly of inferior workmanship is owed with simple plastic. In case of permanent and intensive use of the headset so it is not recommended as a voucher! For casual users, but for the reasons previously mentioned yet in order.
I for one am quite disappointed Logitech - 2 star deduction for it!
