Summary: The other reason I give it 4 is because anything above a sound pressure level of 75 db (75 db should be standard practice) will cause hearing loss. These get up to 113 db, so refrain from blasting sound directly down your ear canals with these babies if you value your hearing.

Excerpt: I have bought these CX300 over a year ago, and they're still going strong. Though they seems a bit flimsy sometimes, the quality of these earbuds in astonishing. It is a good entry purchase for those who want to listen to music with a good set of earbuds. It is a bit different than most earbuds as it has uneven lengths for different sides of the ear.
