Burson Playmate 2 with Westone 4R and Moondrop Variations

• Impedance: 15.2 Ω
• Sensitivity: 118 dB/Vrms @ 1 kHz ≈ 99.8 dB/mW (calc.)
• Frequency response: 9 Hz – 40 kHz (IEC61094, free field); 20 Hz – 20 kHz (IEC60318-4, -3 dB)
• Other: impedance 15.2 Ω @ 1 kHz ±15%; THD <1% @ 1 kHz

Matching notes: At 15.2 Ω and 118 dB/V, the Moondrop Variations is a low-impedance load: about 0.4 V (10 mW, 26 mA) for 110 dB SPL (calc.). Burson does not publish a 15.2 Ω rating for the Playmate 2; its nearest published rating is 3.5 W SE into 16 Ω. The Playmate 2’s under 2 Ω headphone output impedance is less than 1/7.6 of the load. ^{[1] [2] [3]}
