Review: The YEAHBOX boombox - I would recommend the YEAHBOX Sonic boom 3 for party goers who like playing bass music it is fantastic to play this type of music through the YEAHBOX sonic boom and the YEAHBOX app is great to use I do recommend this YEAHBOX boom box for anyone who likes bass.
Review: A Great Sound System - A superb speaker , they say you get what you pay for. The reason it hasn’t got 5 stars is it says 300W when it’s actually 200W ! Plenty loud enough playing Bob Marley was beautiful ! Really good speaker as good as my car subwoofer and you can turn the lights at the end off . So portable to use in any car and legal too. It’s 200 RMS really powerful and can handle the higher sound end without distortion . Use it well below half volume. If you want a car type subwoofer sound system in your place this is the one for you. Battery life seems good ! A good investment.
