The System

Listening with

Focal Clear · Headphones: open-back, dynamic (40 mm Al/Mg M-dome), circumaural · discontinued
  • Impedance: 55 Ω
  • Sensitivity: 104 dB SPL / 1 mW @ 1 kHz ≈ 116.6 dB/V (calc.)
  • Frequency response: 5 Hz – 28 kHz
  • Plugs / cables supplied: 4-pin XLR; 6.35 mm; 3.5 mm cables supplied

Matching notes: At 55 Ω and 104 dB/mW, the Focal Clear is a low-impedance load, and an efficient one: about 0.47 V (4 mW, 8.5 mA) for 110 dB SPL (calc.). Burson does not publish a 55 Ω rating for the Soloist 3X Performance. Its 32 Ω and 100 Ω ratings (4 W XLR / 2 W SE; 1 W XLR / 0.5 W SE) fall either side of it. The Soloist 3X Performance’s 0.5 Ω headphone output impedance is 1/110 of the load. [1] [2] [3] [4] [5]
