A tiny Bluetooth speaker you can literally carry in your pocket sounds like a great concept, but going small -- and I mean really small -- usually means sacrificing sound quality, or more specifically bass performance. Bose's SoundLink Micro, the company's smallest and least expensive Bluetooth model yet, at $100, £100 or AU$150, aims to defy those small speaker conventions. It mostly pulls it off.

In the US and Australia, the price of the SoundLink Micro has dropped $10 and AU$20, respectively, in recent weeks. That's not a huge price cut -- you're still paying a premium for the Bose name and this speaker's portability -- but it's a welcome move in the right direction. (A Bose representative confirmed to CNET that the price cut is, indeed, permanent. Bose has also recently cut the price of its SoundSport Free wireless headphones.)

Available in three color options -- black, midnight blue and bright orange -- the SoundLink Micro is IPX7 certified, which means it's totally waterproof and can be completely submerged. (We dunked it in a vase full of water and it continued to output sound.) While it may be small it does have a bit of heft to it, weighing in at 10 ounces (290 grams). It has a built-in speakerphone for making calls.

Overall I was impressed by its build quality and liked its integrated "tear-resistant" flexible rubber strap, which you can use to clip the speaker onto a bag or just about anything else you want to clip it onto, including your bike's handlebars. That said, the speaker has a bass port on its underside and is designed to sit on a flat surface to maximize bass performance. (I clipped the speaker to the front strap on a backpack and could feel the bass on my chest.)
