Best earbuds (in-ear headphones)

Earbuds are commonly issued as freebie headphones with portable players, but higher-performance earbuds can offer sonic performance that rivals full-size headphones. Their tiny earpieces rest on the outer ear or need to be inserted into the ear canal. Ultracompact and lightweight, earbuds are the most portable of all headphones, and they can provide moderate to excellent isolation from external noise. They also offer little to no interference with earrings, glasses, hats, or hairstyles.
