There are two major types of buyers whom you are likely to deal with, while selling headphones. You need different strategies for dealing with each group of buyers.
The first type of buyers whom you are likely to deal with, while selling headphones, is that of buyers who simply purchase the headphones on impulse. In dealing with this group of headphone’s buyers, you need to appeal to the emotions. If, for instance, you are selling earbuds, you need to focus on your packaging: so that yours come across as the best earbuds in the market, “which are only available for a limited duration of time”. You also need to get your pricing right and indeed, you are only likely to be successful with this group of buyers if you can show them some sort of price advantage. Like, for instance, if you can demonstrate that yours are actually the best over-ear headphones under $200, you may get a few impulse buyers straight away.
The second type of buyers whom you are likely to deal with, while selling headphones, is that of buyers who buy the headphones on purpose: that is, non-impulse buyers. In dealing with this group of buyers, you need to appeal to the mind, to the intellect, on top of appealing to the emotions. That, as researchers from, say, the United States Army will tell you, is much more difficult than appealing to the emotions alone.
