Etymotic ER-6i

  • Superb sound quality
  • Good noise isolation
  • Value
  • Construction concerns
  • Tricky to fit properly
  • Can be uncomfortable
  • Scarce availability

If you don't mind earphones that sit deep in your ear canals, reviews say the Etymotic ER-6i is an excellent choice. Though they don't deliver as much sonic detail as more expensive options costing several hundred dollars, they still make nuances in your music stand out. Passive sound isolation gives you a peaceful listening experience. As with most in-canal earphones, fit is crucial for best bass response, but they can't deliver the boom of higher-priced headphones even under the best circumstances. Many owners report comfort and durability problems, though others are happy with them. Availability is an issue, but you can buy them directly from the manufacturer. The Klipsch Image S4 (*Est. $70) is also worth considering; it gets excellent reviews and sells for less. An iPhone/iPod/iPad-compatible model of those earphones -- the Klipsch Image S4i (*Est. $100) -- is also available.

CNET and compare the Etymotic ER-6i to other headphones and give useful information on performance and comfort. PC World Good Gear Guide (Australia) also supplies a detailed review. Though less extensive,'s review confirms the conclusions of other reviewers. User reviews at are definitely worth a read, with more than 950 owners giving their views on issues such as comfort and durability.

Steve Guttenberg describes the Etymotic ER-6i sound as "extraordinarily fine." Compared to the full-size Grado SR60 headphones, the ER-6i sounds cleaner, though bass response is more impressive on the Grado. However, thin wires on the ER-6i tangle easily, and the earphones can be uncomfortable for some.

Jeremy Horwitz, editor of this iPod and iPhone accessory review site, is impressed with the detail on the Etymotic ER-6i, though he says it's not quite as "mind-altering" as the more expensive ER-4P. Noise isolation is also excellent, and the ER-6i earphones are lightweight.
