Let's start with design. The Disco 2 is a one of the tall Bluetooth speakers out there, it's made of black plastic and fabric mesh but is also available in white. It is pretty bulky but I believe this gives better sound as there's more room for air which gives better bass. It does have some nice weight to it which prevents wind blowing it over outside.
First impressions of sound quality, this is worth the price. Honestly, to my ear everything was well balanced. I'd say, the highs were very slightly lacking but everything else is pretty perfect. There was a slight issue at high volume where there would be slight distortion. This didn't really bother me because I don't listen to music loudly outside or through a speaker like this. I found it more suited to music in the background. It will go pretty loud but I'd rather save that kind of experience for my 1000w system.
So for me, the battery life was excellent, it has an internal non-replaceable rechargeable battery. I tested 2 scenarios, music at a comfortable level it lasted 11 hours. I was very impressed by it! Then I tested it at 1 from max volume and it lasted a respectable 7 hours. Although I'd never use it at this volume, it was great that it lasted so long for people that would use it at that level.
On the top of the speaker there are simple audio controls that are backlit. Vol Up/Down, Play/Pause, Backward, Forward and Power.
I have often found that when it comes to audio equipment, you really do get what you pay for. At the time of this review the Disco 2 is £50 which is a good price. It is great quality sound, feels well built and comes with a premium feeling felt baggie. Even if you don't have a Bluetooth device like an iPod Shuffle, it comes with a 3.5mm port and small cable. So if you want a good sounding, well built, easy to use wireless Bluetooth speaker, this one is ideal.
