Pros Really locks in my ears
Cons Sound is normal with these budget type ear buds
Summary I could not tell any difference using the cheap ear buds that came with my Sony MP3 player. I was looking for replacement type that would stick and hold in your ear like these Denon which they do. Sound quality is okay. I was using the FM radio section of my MP3 when judging. I normally use my AKG K240 Studio headphones for serious listening plesure. Again, I bought these earbuds b/c they stick and hold in your ear not just rest on your ear.
