And, well, it’s half-right. > The most obvious point of difference is the set EQ sliders on top of the speaker, which allows you to change the balance of songs on the go. There’s also the fact that despite being over half a meter tall, it’s portable and has a battery that lasts for around 8 hours of play time.
