Good build quality and excellent sound output. When i connect my 300 ohms headphones to my laptop, they performed like the volume was turned very low. By connecting this small amplifier between my laptop and my 300 ohms headphones, the volume is high and the sound quality is excellent. The only thing it needs to be added is a plastic enclosure. Highly recommended.

i 3 pezzi ricevuti avevano: - resistenze sbagliate sulle due reti antiinstabilità (montate due resistenze da 4,7kOhm anziche 4,7 ohm, con relative forti instabilità) - la pista del circuito stampato che dovrebbe collegare direttamente massa segnale entrante ai relativi terminali del potenziometro mancante, con relative problematiche di rumore

ei näköjään pääse eteenpäin ilman että tästäkin mainitsee jotain. Pieni, ajattelin tehdä kuulokevahvistimen televisioon.

very small solid circuit, practical and well done assembly. The board is really good. And the price is ridiculous compared to the components. Used as an amplifier for a Bose QC35 bluetooth headphones the sound is more than good.
