Sound Output it comes with 3.5 mm jack connector slot with USB cable & radio as well.
It has SD card slot also to direct listen songs from your memory card. User Friendly just 4 buttons on top of it. while I am driving car I use this speaker and I receive calls on this speaker and voice call clarity is pretty impressive but when their is outdoor noise we can’t voice of person whom I am talking I need but speaker near to my ears.battery is also good but main thing is sound which is very low so that’s the reason I won’t suggest anyone to buy this product.it isn’t worth for your money.
