These are good headphones. They are nice and loud with good sound, easy to set up, and block out sound well. I am still at 50% case charge (on the charge they came with) and have listened to over 20 hours. I am happy to recommend them. For the rest of the review I will be comparing them to their V7 model that I was using previously.The sound quality and max volume of the G17 is better the V7.The case for the G17 is longer then the V7 which I like because it feels less likely to fall out of my pocket.The G17 has a physical button which I like over the V7's touch sensitive surface (I tend to miss the surface and give the wrong command). I also find the taps/presses used for commends more intuitive with the G17.I found the getting the G17s seated properly less intuitive then the V7s. The G17s over the ear pieces are stiffer and create a more elongated shape compared to the V7s. The V7s over the ear pieces are better for my shape of ear. Though if my ears where any bigger the V7s would probably be too small.
