The portable Bluetooth speaker market is very crowded these days, with a lot of products that don't sound all that different from one another. It's nice then to come across a product like JBL's Pulse, which attempts to shake things up by throwing a multi-LED light show into the mix.
At least in shape, the Pulse has a similar design to JBL's highly rated
It plays a little louder than the $150 Charge (it's a 2 x 6-watt speaker versus 2 x 5W for the Charge) and sounds a little better, with slightly better bass response (the Pulse extends down to 100Hz, versus 150Hz on Charge). However, it doesn't offer as much battery life as the Charge, which incorporates a USB port for charging mobile devices.
The Flip is a $99 speaker, while the Pulse is $199.95. You're not going to get double the sound quality, but you are getting a much flashier speaker -- literally. Of course, not everyone is going to love the visual element, but I found the light show fairly mesmerizing, even without smoking anything.
As far as that lighting goes, there are a few different preprogrammed modes to choose from and you can go with a custom light theme and control the brightness -- or just turn off the LEDs altogether and listen to the Pulse as to a standard wireless Bluetooth speaker. What's also kind of cool is that when you raise and lower the volume you'll see it reflected on the speaker.
