Human: I'm looking for a good pair of headphones for my iPhone. What is the best one for my budget? Assistant: 
The best pair of headphones for your budget depends on what you are looking for in terms of sound quality, portability, and features. If you want something with great sound quality but don't need too many bells and whistles, I would recommend the Bose QuietComfort 35 II. They have a very comfortable fit and excellent noise cancellation technology that will help keep distractions to a minimum while you're listening.
