In the battle for the most interesting looking Bluetooth speaker, Philips may have just sealed the deal with the SoundShooter. The super compact speaker easily clasps onto a backpack, belt loop, or any of your gear with the attached carabiner. Available in a few different vibrant colors (or black, if you’re not looking to stand out quite as much), the SoundShooter is surprisingly powerful for such a tiny little unit (that’s what she said). The built-in rechargeable battery can last up to eight hours on a charge, and the integral microphone allows it to handle calls as well. Perfect to add a soundtrack to your next excursion.
