Panda k-31 megaphone, OK?
As far as I know in the domestic well-known brands are victorious, Longines and other brands, I now use a victory this brand, personally feel that this brand of loudspeakers in terms of sound quality and quality is doing pretty good, also used nearly two years' time or keep such a good sound quality!
Panda megaphone? This brand, I had never heard, this should be a small workshop production of loudspeakers, estimation quality and sound quality is not good, I suggest you buy a megaphone or if buy some of the more well-known brand is better, at least get a certain guarantee in quality
I haven't even heard of this brand. It should be some kind of loudspeaker produced by a small workshop. I don't think the quality and sound quality are very good either
