I used this sound system from last 6 month.i must say this I ball booster 5.1 speaker sound system is best .it consist 5.1 speaker.1 manual book. 1 remote control.and wire.you connect this sound system via blutooth, pendrive, memory card, and also dvd player.and it has FM radio.just love it guys..if you want to connect with pc, you surely connect with pc.every speaker is full wood speaker.you can play this sound system like 2.1 speaker or 5.1 speaker.Remote control need 1 battery.so I say overall this is just a good system.
