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.
