Review: Searched Far and Wide for This Speaker - I am so happy I finally found this Wonderboom model. I had a great Bose 360 portable speaker that was ruined from being left outside too long. That model is no longer in production - and it took me over a month to find a speaker comparable to what I had. I ordered and returned 4 portable speakers before landing on the Megaboom 4 - - and after an hour of testing a wide range of songs I couldn't be happier. What makes this speaker so great is the quality and variety of its sound. It sounds great on its own, but the app has an EQ slider with several presents and a custom setting to find the right levels to your taste. (EX - I found the preset for close quarters to work best for jamming to songs in my kitchen.) It's a bit larger (and heavier) than I was expecting, but still fairly easy to throw into your luggage. And very much worth every penny when you compare against smaller and cheaper 360 speakers that are under £100. The ones I tried all had terrible, unbalanced sound in comparison. So in my opinion the Megaboom 4 is worth every penny!
Review: Top rechargeable Bluetooth speaker. - Best speaker ever. 360 surround. Seen this on holiday came home and purchased 3 one on each floor so I can party up all round music,great sound Bluetooth and rechargeable. Amazing.
