I bought sonilex wireless bluetooth speakers from a local shop in delhi. They had a decent look and a fair range of features. They had a usb, sd card and an aux cable port. And all this only for 400 bucks. I was so overwhelmed, I immediately bought them . But after using them, they were a total disappointment. Their sound was very sharp and harsh. Secondly, they had a pathetic battery. After charging them for the whole day they only worked for 3-4 hrs.
So if you are buying this product do not keep your hopes high.
