Design: 5/5
-As Soon we unpacked, we say "this is good cam", chromed edges, outline brushed aluminum dyed black, it's clean, it works. I personally love the design. It is robust and appears solid.
Autonomy: 4/5
- Decked out in a 1500mah lithium battery manufacturers data promise 10 hours of continuous operation. In practice, it takes 10h EASY see much more if used at medium power. Charges in about 3 hours, I turn a point because we could decrease the charging time and increase autonomy.
Connectivity: 4/5
-Free Bluetooth without too much trouble to any device. One has a double flat-jack cable supplied, which is pretty cool.
-We Nevertheless regrets the lack of NFC that would have given a little more. I take off a point for that.
Use: 4/5
-Here We still have a perfect compact speaker for mobile use. In the photos above, we can compare with xiaomi and the muse aukey sk-m2 (which I will publish the test soon).
If not for the keys is the classic 3 keys, less, more, and play / pause.
Finally, to 39.99 on Amazon, it's a nice offer for a small quality speaker and design and perfectly nomad for someone who is not looking for raw power.
