The ER-6i is a screaming value. Slightly warmer sounding than the normal ER6, it is well balanced and coherent, punchy and articulate; these earphones deliver!

6i isolator earphones are designed specifically for use with the Apple iPod and other small portable players, offering 8 dB higher overall sensitivity and slightly more bass than the ER-6 isolator earphones.

For Travel and Personal Listening

• Use with MP3, CD, DVD players and personal computers
  
• Lightweight, compact, fits in your pocket; no battery required
  
• Highest noise isolation (except Etymotic's ER-4 MicroPro earphones)
