Very nice as expected

The System

Listening with

Sony SS CS5

beyerdynamic T1

Focal Elegia · Headphones: closed-back, dynamic (40 mm Al/Mg M-dome), circumaural · discontinued

Impedance: 35 Ω
Sensitivity: 105 dB SPL / 1 mW @ 1 kHz ≈ 119.6 dB/V (calc.)
Frequency response: 5 Hz – 23 kHz
Plugs / cables supplied: 3.5 mm cable (1.2 m) (per datasheet)

Matching notes: At 35 Ω and 105 dB/mW, the Focal Elegia is a low-impedance load, and an efficient one: about 0.33 V (3.2 mW, 9.5 mA) for 110 dB SPL (calc.). Burson does not publish a 35 Ω rating for the Funk. Its 32 Ω and 100 Ω ratings (2.5 W SE; 0.6 W SE) fall either side of it. The Funk’s under 2 Ω headphone output impedance is less than 1/18 of the load. ^{[1] [2] [3] [4] [5]}

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.
