The Nightingale is Sivga's first planar magnetic earphone, featuring a 14.5mm planar driver. The Dual Magnetic Driver design uses two rare iron-boron alloy magnets for high performance and a consistent soundstage. Bass is unobtrusive, mids are rich and highs are smooth. In addition to an elegant look using aerospace-grade aluminium-magnesium alloy and solid wood, Sivga also made sure the shape was comfortable to wear. The package includes a cable with a 2-pin 4.4mm connectors, a hard case, an ear tip case, and silicone ear tips in various sizes.
