### Instruction: What are some things to remember when buying a new pair of headphones?
### Response: There are many criteria when one can keep in mind when purchasing headphones.
1. Purpose: the purpose of usage should be clear in mind, i.e., whether it's for hearing good quality music or for work like taking video calls.
2. Price Performance: Money is always an important consideration when it comes to any sort of purchase.
3. Active Noise cancellation (ANC): Although noise cancellation is coming with most headsets nowadays, the quality of ANC might vary from one piece to another. So it's always good to read some reviews around it.
4. Mobile application and features: It is almost a norm now that every major headset company has developed the corresponding mobile application with some add-on features. But some companies offer much for fine-grained controls than others.
5. Carry case: If you are a frequent traveller, then a compact and robust headset carry case might be good to have in certain situations.
