The Para is an open-backed planar magnetic headphone from Moondrop, built with a very low impedance and correspondingly easy amplifier matching. This model marks Moondrop's move into full-size planar magnetic headphones, a comparatively recent step for a brand known for its extensive in-ear catalogue.
Key specs that matter
Rated response is 15 Hz to 53 000 Hz, a wide window typical of planar magnetic driver technology. Sensitivity is 101 dB per milliwatt into an unusually low 8 ohm impedance. Connector is 3.5mm.
Sound and use context
Expect the fast, detailed character associated with planar magnetic drivers, with the open-backed design favouring soundstage width over isolation.
Pairing
The low 8 ohm impedance and 101 dB sensitivity mean this headphone is easier to drive than many planar magnetic rivals, though a dedicated headphone amplifier still supplies more current than a basic phone output.
Alternatives
Other planar magnetic headphones typically demand considerably more amplifier power than this low-impedance Moondrop design, worth comparing on ease of drive if avoiding a dedicated amplifier purchase is a priority.
