Our Review/Thoughts
Both units sound great and have a battery that lasts a long time
There is an up/down volume control on the left ear cup
You won't understand until you do
I've used the headsets for a couple of days without recharging them
All you need do is briefly press the power button to answer an incoming call
I have also tested the red/black version and it features a subtle use of red as an accent color that works really well
