As a person who is involved the manufacture or in the sale of headphones, you need to do everything in your power to avoid having people doubt the quality of your headphones. To do this effectively, you need to be aware of the factors that are capable of making people to doubt the quality of the headphones.
The first factor that may make people to doubt the quality of headphones is poor packaging. You may very well be having the best headphones (objectively speaking), but if your packaging is poor, then people will start doubting the quality of the headphones. This is because perception is reality to the perceivers.
The second factor that may make people to doubt the quality of headphone is poor finishing. Like if you have some wires that are unsheathed, or if the coloring of the headphones is not well done, people may be inclined to doubt the quality of the headphones. Again, even if yours are actually the best all genre headphones, if the finishing is poor, people will doubt the headphones’ quality.
The third factor that may make people to doubt the quality of headphones is if the price of the headphones is too low. People always assume that very cheap things are of poor quality –regardless of the reality. This is why, for instance, the cheapest vehicle models like, say, Mahindra from India are regarded as being of dubious quality – in spite of the fact that, objectively speaking, Mahindras are actually decent, high quality vehicles.
