[@RumblePirate]

True, this is nice for small speakers on one lipo or 3 AA batteries. But as you said, volume knob based board is better. Small 87% efficient, and very cheap ... How did you guys feel about the sound, the treble and the bass , lol for this small wonder ?

[@WhatIThink]

It sounds very satisfactory as per its capacity. Just use quality speakers.

Kharab to nahi hota lekin magnet power low hi jata hai. Lekin minimum 5 years . Coil agar overheat na ho to koi fark nahi padta. Local speaker jaldi weak hota hai,branded nahi. Baaki agar dust aur rust problem na ho to koi problem nahin aati.
