SuperTooth has many high-quality speakers for sale. Today, we're looking at the Disco Twin which they just released not to long ago. It's basically two Bluetooth speakers that can connect to your phone, tablet, PC at the same time. It works with any Bluetooth enabled device. I was able to test it on the Nexus 7, Nexus 4, Samsung Galaxy S4, HTC First, and the Chromebook Pixel. They worked great with every device. The two speakers can be up to 10 meters apart, as well as the device you have connected to them. I was able to go to the other end of my house with the Galaxy S4 in my pocket and the speakers were still able to play music from it. Which is really great.
The Disco Twins can operate on it's own battery. They both have built-in batteries and it comes with a charger for each speaker. The battery I found to be able to last around 12-16 hours of use. That's straight music, movies, etc. They are both pretty loud, so they'll work great outside. In fact, I used them outside for Mother's Day and they provided awesome sound out there. Additionally, as you can see from the images, the Disco Twins do collect dust like a magnet. That's the only real down-side I can see to these speakers.
These SuperTooth Disco Twins are great Bluetooth speakers, and probably the best I've used to date. I'd have a hard time not recommending these to those looking for some good Bluetooth speakers. They cost about $200 from SuperTooth, at the time of writing this. But they are well worth the money. Check out their site for more information
