Violin slightly heavier than an acoustic violin (approx 200 gr.) Its very nice comparable to a good acoustic violin. When used with the original headphones the sound is slightly amplified. I use it with an acoustic amplifier STAGG 10AA with or without a trendy studio headphones directly to the amp and then the sound is perfect. Used only sound is unobtrusive and can in no case disturb the neighbors. Too bad it is only equipped with a 9V battery and we can not connect it to the mains.
