"No volume control on mic (unusable for PC use)"2.0 starson by styles80
Pros: Stylish, great noise reduction, great for cell use
Cons: Can't use it for PC (volume too low)
Summary: It's really unfortunate that there's no real sound or mic volume control, which makes it relatevely unusable for bluetooth connection to the PC, because the recording volume comes in at about 1-2 bars out of 10 (optimal audio range for speech recognition, etc. is at 6-7 bars).
