Excerpt: This speaker is even smaller and more portable than the Logitech Mini Boombox. Again, it uses Bluetooth to play songs wirelessly from your phone or tablet. The sound might not be as hefty as from the Logitech, but it’ll fit in your pocket, and give you eight hours of music from one charge. Music to our ears.
Conclusion: The X-mini KAI is a great device, perfect for travelling and teleconferences. It is small and lightweight and produces an outstanding sound for its size. The battery is an issue, but this shouldn’t bother most people, as it doesn’t take long to recharge.
Pros: Small size; big sound; Bluetooth; microphone
