Wow im amazed with with the sound the bass is loud i have this for my pontoon boat great boom box
Super skeptical being one of the firsts.. but it’s a F*** Yeaaaahh For Yeahbox. It’s louder than a boombox 3 and worth the $259 . Buying another one for sure for the TWS. It is a bit on the heavy side. But she’s going to be a great companion in the SxS and the pontoon boat! Thank you Yeahbox :) no ragrets! Not even one little letter !! lol.
I really recommend it.
Super loud and unique sound
I had asked my grandson what he wanted Nana to get him for his 16th birthday. He said he wanted a powerful loud speaker that is wireless and has blue tooth so he could carry it around easily. He already has one on the 4-wheeler but he wanted a mobile speaker. After weeks of research...and buying the wrong type the first go around...I came across this speaker. I sent it to him to review and see if this is what he is looking for. He absolutely LOVES this speaker. We live on a large farm that has a set of train tracks very close. This speaker has so much boom that the train doesn't drown out the music!!! I'm serious! This speaker is DEFINITELY worth buying if you want great bass and extreme loudness!! My grandson said this is the best thing...besides the 4-wheeler...that he got for his birthday this year! So glad to have purchased it.
I have 2 jbl boombox and this yeahbox blows them out the water. This thing is big compared to jbl boombox. The sound and bass that comes out this thing is amazing. Buying another one for sure. Can’t beat the price and made with good material.
