Very good quality for listening China anime songs
It's my first time for buying a headphone, and I do not regret
Satisfied purchase with black friday discount！

Excellent products!
Everything is high quality, from exceptional manufacture to excellent sound!
Sivga Robin has an excellent tuning for audio listening with equalizer set o zero for all frequencies.
Sivga Luan has an excellent and refined clarity on all frequencies and is quite a studio monitor. For day by day listening it needs only a very small increase on the sub base frequencies and gives a dream sound!
Very satisfied with my purchase!
