Sony MHC-V11 speaker, powerful. It has Bluetooth connection, its sound is very strong. It has limited DJ control, I haven't tried it. It has NFC feature, bring any phone close and it connects. It has a CD input, I haven't tried it and it doesn't open. Of course, it has inputs shown in the picture for those who want to add system speakers, I haven't tried them. It has some functions controlled by the buttons shown in the pictures. It works with electricity, not a battery, meaning it doesn't charge and you can't take it anywhere, no. It's really nice and powerful for someone who wants it for their room or majlis. It's working, there's nothing wrong with it. DM or WhatsApp, don't call, just put your offer.
