Burson Playmate 2, Burson Super Charger 3A, HiFiMAN Edition XS, Sennheiser HD 650

Great all-in-one DAC amp especially once changed with the V6 Vivid opamps. Totally different level of listening experience and more than enough power for most planes and dynamic headphones

The System

Listening with

HiFiMAN Edition XS · Headphones: open-back, planar magnetic, circumaural

Impedance: 18 Ω
Sensitivity: 92 dB (reference not stated by HiFiMAN)
Frequency response: 8 Hz – 50 kHz
Plugs / cables supplied: not published (HiFiMAN spec page lists no connector)
Other: weight 405 g; Stealth magnets

^[1]

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. ^{[2] [3] [4] [5]}
