I brought this speaker a month ago and amazed by its sound quality, recently I brought a new computer for my office so I decided to buy a cheap speaker for it and order this.but the sound quality really surprised me .because I sound great.i m also use this with my phone and its working great.its cheap but really great. its came with a 2.0 USB port and 1 3.5mm audio jack.just plug in and forget it. I buy this in just 200 rs.
