Comparing Funk with Yamaha A-S301. First minutes of listening. Wow!!!

The System

Listening with

Heco Victa Prime 202

Piega TMicro 40 AMT

beyerdynamic DT 770 PRO 250 Ohm · Headphones: closed-back, dynamic, circumaural

Impedance: 80 Ω (page default; 32 and 250 Ω versions sold)
Sensitivity: 96 dB SPL (reference not stated on page)
Frequency response: 5 Hz – 35 kHz
Plugs / cables supplied: straight cable with 3.5 mm plug and 6.35 mm adapter (current version)

^[1]

FiiO FH5 · Headphones: in-ear (IEM), hybrid 1 dynamic + 3 Knowles BA

Impedance: 19 Ω
Sensitivity: 112 dB/mW ≈ 129.2 dB/V (calc.)
Frequency response: 15 Hz – 40 kHz
Plugs / cables supplied: 120 cm cable, MMCX, 3.5 mm plug
Other: max input power 100 mW; 8 g per earbud

Matching notes: At 19 Ω and 112 dB/mW, the FiiO FH5 is a low-impedance load, and an efficient one: about 0.11 V (0.63 mW, 5.8 mA) for 110 dB SPL (calc.). Burson does not publish a 19 Ω rating for the Funk. Its 16 Ω and 32 Ω ratings (3.5 W SE; 2.5 W SE) fall either side of it. The Funk’s under 2 Ω headphone output impedance is less than 1/9.5 of the load. ^{[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.
