"This has huge design fault in headband. I bought this from lenovo hoping to get quality but its a super faulty headband. Don't even spend any time buying it as even $1 headband has better fit.
As far as ear cusion and voice quality, it's ok if lenovo can replace headband.
My head is still hurting after 2 weeks.
also, you cant use for iphone or cordless phone or even PC which has same speaker and mic pin."
"I got a medium/normal size head, and feel very uncomfortable to wear this, because the Brain-Squeezing headband, since its not round (some odd design)"
