Conclusion: Philips’ SoundShooter SBT30 is no portable hi-fi, but it is one of the best-sounding tiny Bluetooth speakers we’ve come across, and certainly the most rugged. For adventurers needing a small, lightweight device that sounds better than their phone, the SBT30 is hard to beat.
Pros: Fuller sound than most competing speakers, Includes speakerphone, Carabiner is surprisingly useful/ super portable, Charging cable doubles as input cable, Surprisingly long battery life
Conclusion: The Philips SoundShooter Grenade chucks out a big sound for a portable speaker . It's particularly easy to carry, though a proper cover for the speaker diaphragm would feel a bit safer when you chuck it into a bag.
