Excerpt: These days, most in-ear buds require you to squeeze them right inside your ears. For some people this is too uncomfortable, and while many people really value the degree to which the seal blocks outside noise, others would like to hear at least some of what’s going on around them. Of course, you can get in-ears that don’t burrow, but these aren’t great at staying in your ears if you’re out and about.
Pros: Firm fit without burrowing
Cons: Flat, cluttered sound, lacks detail, peculiar fit in ears means sound lacks punch
