Having had X-Mini 2 speaker I wanted X-Mini Max 2, but then HAPPY came out and I was dreaming about it days and nights. So, I've got it!
Firstly, loudness - it is much louder than previous xminis. It doesn't overload you ears with trebles but it s...Read moreounds good and loud. 5/5
Sound quality - 4/5. Would like to hear sub bass freqs too
Ease of use and responsivness - 4/5. I'd like it to play my MP3 files straight away as I start it and press PLAY. However, there is a bit of delay that's why 4 stars. Overall it is very easy to use, even despite next track/volume up-down function been united in 1 control jog it is not incovenient and got used to it quickly.
Connectivity - convenient is a fact that you can charge and transfer data at the same time via computer's USB. I was expecting X-Mini to ask us to owe SD card reader for file transfers.
What else? Didn't like hiss coming out of speaker if playing on low volume level. Also play/on-off button is so sensitive (at least on mine) that it turns itself on sometimes in my bag.
Battery life? Good, plays and plays.
Overall - 4.7 out of 5 just because of little "inconveniences" mentioned above
