Audio Appraisal highly recommended Sivga SV021
"The Sivga Robin is a supremely comfortable pair of headphones with wonderful build quality and evident craftsmanship throughout. The fact that Sivga chose to use hand-finished wooden enclosures and custom drivers at this price should be commended, when they could quite easily have produced another typical plastic headphone at this price with off-the-shelf components.
Sonically they’ve become something of a faithful listening companion for the cold winter nights. Highly recommended."
