20th Anniversary Fontopia® Headphones

MDR-EX70LP
msrp $49.99
MDR-EX70LP
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
  • Two 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/m3 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
