There are lots of great speakers out there, and picking the right ones can be a big headache. Any speakers are an upgrade over what comes stock in your laptop or monitor, but are a massive upgrade, and right now they're $40 off over at Amazon.
These twin bookshelf speakers comes with everything you need. With Bluetooth, you can easily control the speakers and no unsightly wires will criss-cross over your workspace. The speakers also come with digital and analog inputs, meaning these are much more than just a great pair of office speakers. They'll play nice with turntables as well. You can even connect to your TV, and you'll get better sound than the stock speakers stuck in your display.
It also doesn't hurt that Edifier pays attention to aesthetics. With what the company calls a "sleek piano finish," this isn't some ugly gadget mucking up the feng shui of your workspace. It's design isn't meant to disappear seamlessly, so all you get is great sound. Not bad for only $160.
