Burson Conductor 3X GT, Focal Clear

DHL Express delivered my package on a Sunday that is unbelievable but it happened. Great service from Burson and DHL.

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 Conductor 3X GT. Its 32 Ω and 100 Ω ratings (8 W XLR / 4 W SE; 3.8 W XLR / 1.9 W SE) fall either side of it. The Conductor 3X GT’s 0.5 Ω headphone output impedance is 1/110 of the load. ^{[1] [2] [3] [4] [5] [6]}

Specs from manufacturer data unless a source below says otherwise. “calc.” values are worked out from those figures (V = √(P × R); 110 dB SPL used as a loud reference level). Gear listed without specs is not in our spec library yet.
