Key Features
Fontopia® Headphones in-the-ear design :  
  
fits snugly, yet comfortably inside the ear; eliminates the headband so you can enjoy music while exercising, skating or dancing
Sony's first closed-type Fontopia design :  
  
reduces outside noise for high-intensity listening; helps generate powerful, resonant bass response
New, super-small 9 mm drivers :  
  
are a key enabling technology; ultra-compact drivers produce powerful sound with space left over for the sonic isolation of Sony's newly-designed silicon earbuds
Soft, silicon earbuds :  
  
reduce outside noise, provide long-lasting comfort, hour after hour; the earbuds are washable, removable and replaceable
Three sizes of earbuds :  
  
accommodate a full range of ears
Long-throw PET diaphragm :  
  
or deep, extended bass down to an incredible 6 Hz; low mass for extended high frequency response all the way out to 23,000 Hz
400 kJ/mã Neodymium magnet :  
  
for maximum energy in minimum size; ounce for ounce, this high-power Neodymium is far more powerful than conventional Samarium Cobalt or Aluminum magnets; even with the small, 9 mm drivers, Neodymium achieves 100 dB of sound pressure output from a modest 1 mW input power.
Oxygen-Free Copper (OFC) cord :  
  
for high signal transmission, low noise
Stylish, Neck-Chain Cord :  
  
Gold-plated mini-plug :  
  
for exceptional corrosion resistance, superb conductivity, low noise
Streamlined, compact case :  
  
neatly stores the ear-buds and headphone cord when not in use; vivid purple styling; high-impact case is ideal for carrying in a pocket or backpack
New case design :  
  
minimizes cord tangles; partial winding can shorten the effective cord length during use
