Why I keep 4 pairs of headphones with me at all times (and the unique role each one plays)

Here is a 171-word summary of the news article: The author keeps four different pairs of headphones with them at all times, each serving a unique purpose. The first pair are noise-cancelling over-ear headphones used for focused work and listening to music. The second are wireless earbuds used for exercising and casual listening. The third are a wired pair of in-ear headphones that provide high-quality audio for critical music listening. The fourth are a backup pair of basic earbuds, kept as a spare in case any of the others are lost or broken. The author argues that while a single 'all-in-one' pair of headphones doesn't exist, this curated collection of four different types meets all their audio needs. Each pair has distinct advantages and is selected based on the specific listening environment and activity. This redundancy ensures the author is never without a suitable pair of headphones, making them a critical part of their daily carry.
