Final answer:
I initially had a negative attitude towards a brand of headphones based on online reviews, but my opinion changed when I tried them myself.
Step-by-step explanation:
An example of a life experience where I had an attitude about a product/service not based on personal experience or use is when I had a negative opinion about a particular brand of headphones because of online reviews. Despite never trying the headphones myself, I believed they were of poor quality based on the negative feedback I read online.
However, my attitude changed when I had the opportunity to try the headphones myself. I borrowed a pair from a friend and was pleasantly surprised by their sound quality and comfort. This personal experience made me realize that online reviews can be subjective and that firsthand experience is crucial in forming an accurate opinion.
