I want a headphone, named "Quiet Comfort (QC)" series made by Bose.
It eliminates noise and makes us comfortable though it is too expensive.
I used QC2 in Bose shop today. I wanted to buy it, but I also wanted to use QC3. I asked a clerk when it will go on sale, then he told me that it will be put out at the beginning of October.
I'll buy the headphone in October!
