SIVGA Anser is a relaxing, slightly warm open-back that focuses more on bass quality than quantity, with comfortable fit and a premium mix of metal and wood. I like it as a safe all-rounder for music, movies, and casual gaming, especially if you want a forgiving tuning for rough recordings.
Pros
+Good design and choice of materials (metal headband/yokes, wooden CNC cups)
+Comfortable for long sessions with improved headband padding
+Relaxing, warm, forgiving tuning that suits many genres
+Easy to drive from portable sources (38 ohms / 105 dB)
Cons
-Stock braided cable is microphonic
-Resolution and microdetail are not class-leading for the price
-Treble lacks air, sparkle, and extension for my taste
-Soundstage is only average despite open-back design
