choosing headphones
Earbuds or headphones: Earbuds are for people who are short on space while headphones are great if you enjoy putting them around your neck while you're walking.
Evaluate sound isolation: This refers to how well they keep music in and block outside noise. Sound isolation will also help save battery life.
Test them out: The best way, really, to know if headphones can go loud enough for you is to test them out.
Look for impedance: To get the best out of your headphones, you should match the impedance of the headphones to the audio equipment you are using.
Use your ears: You are the person who is going to be using these headphones. The sound quality is not going to change just because of prices
