Third-party reviews

What customers like about Stax Sr 207

  • Exceptional clarity and transparency for the price
  • Lightning-fast transient response and high detail retrieval
  • Lightweight and comfortable for long listening sessions
  • Excellent value for an entry-level electrostatic system
  • Sturdier build quality compared to some newer Lambda models like the L300
  • Accurate sound imaging and a wide, airy soundstage
  • Often considered more balanced and even-sounding than the SR-507

What customers don't like about Stax Sr 207

  • Lack of 'visceral' bass impact or 'slam' compared to dynamic or planar headphones
  • Pronounced 1.5kHz midrange 'shout' or 'bump' that some find intrusive
  • Sub-bass roll-off is more sudden than higher-end Stax models
  • Earpads can be difficult to get a perfect seal with due to being somewhat stiff
  • Open-back design leaks sound and provides zero isolation from room noise
  • Proprietary 5-pin 'Pro-bias' connector limits compatibility with standard audio gear

Verdict

The Stax SR-207 is an entry-level open-back electrostatic 'earspeaker' featuring a 2-micron thick diaphragm and a push-pull driver system that delivers a frequency response of 7 Hz to 41 kHz with a sensitivity of 101 dB. Weighing 340g and utilising a 580V DC bias voltage, it is primarily celebrated for its exceptional transparency, lifelike detail retrieval, and fast transient response that outpaces most dynamic and planar magnetic alternatives. Key strengths include a wide soundstage, lightweight comfort for long sessions, and high-quality genuine sheep leather earpads. However, its performance is limited by a requirement for a dedicated electrostatic energizer (amp), a roll-off in sub-bass weight, and occasional sibilance in the higher frequencies.
