VOICE QUALITY - 3/5The voice quality of this, as described by people I speak with, is "fine" and basically not as good as a blue yeti but better than a phone.NOISE CANCEL - 1/5The noise cancellation, AWFUL. They can hear everything in the background. This could actually be "good" depending on what you're trying to do with it though so I won't really count this against them.EASE OF USE - 0/5Worst microphone ever, ever in terms of ease of use. Randomly dies without a good indicator. Turning it on/off you have to hold it down for a few seconds which is normal but for some reason, it's hard to get it down. It doesn't connect sometimes, and this is the only Bluetooth device that does that. So you have to turn it off and on, making it more complicated. If you plug it into USB to charge it then it also for some reason resets and has to be turned off/on again and again til it works. Cuts out randomly, causes interference with other Bluetooth devices but maybe its not their fault.BATTERY LIFE - 1/5Really bad battery life, lower than advertised. They could have made it slightly longer to increase it maybe. I get like 3 hours. Battery life keeps getting worse fairly quickly. There's no "auto turn off" or "standby" feature as far as I can tell so if you accidentally leave it on, it's dead. I see it plugged in a lot more than I see it wireless.
