Scosche's IEM856 In-Ear Monitors give a rich, deep-sounding quality, travel well, and have become one of my go-to headphone choices this year. Credit the sound quality to the same kind of dynamic driver/balanced armature combination found in many high-end headphones, which gives you booming bass, crisp highs, and everything in between. The IEM865s are built tough to stand up to lots of jamming into and out of pockets and carry-ons, and the thick, linguine-shaped cord, which resists tangling and is as strong as any cable here, has a great oversize volume control. (The same flat cord can be found on a-Jays Four earphones from Jays, which go for $70.) Admittedly, they're not cheap, but you can find them online for a fraction of the sticker price.
