AKG N60NC, Burson Playmate 2, Edifier R1600TIII, Sennheiser HD 650

Trying it out for the first time at the moment. It’s my first Burson product.

The System

Listening with

Edifier R1600TIII

Sennheiser HD 650 · Headphones: open-back, dynamic, circumaural

Impedance: 300 Ω
Sensitivity: 103 dB SPL @ 1 kHz, 1 V (as published) ≈ 97.8 dB/mW (calc.)
Frequency response: 10 Hz – 41 kHz
Plugs / cables supplied: 6.35 mm stereo jack plug (3.5 mm adapter)
Other: THD <0.05% (1 kHz, 1 V); 42 mm transducer

Matching notes: At 300 Ω and 103 dB/V, the HD 650 is a high-impedance load that needs voltage more than current: about 2.2 V (17 mW, 7.5 mA) for 110 dB SPL (calc.). Burson rates the Playmate 2 at 0.15 W (SE) into 300 Ω, which is about 6.7 V RMS (calc.), roughly 10 dB more than that. The Playmate 2’s under 2 Ω headphone output impedance is less than 1/150 of the load. ^{[1] [2] [3] [4]}

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.
