1. Which brand is Hong Kong's best selling headphone or earphone? In my opinion these would be the Apple iBuds or Beats.
2. Which brand's HEADPHONE or EARPHONE would you prefer. I really like Hi-Fi Man or Stax electrostatic headphones. For earphones I prefer Shure.
3. Why would you buy for your personal use such as walking on the street, listen music etc
or giving gifts for your partners, friends? See question 2. As gifts, those would be too expensive. I would gift Sennheisers since they have different price levels or Shure.
3. What is your age group i.e. 1) 15-20 years, 2) 21-35 years and 3) 35-50 years old or 4) 50
35-50
