Imaginative Kiso Harmonica
The overall sound is that it prioritizes the midrange and highs, since the lows are on the average side. If you're expecting it to have that traditional aggressive bass punch and slam, this is not it, since this only uses a dynamic driver and it has no passive radiator.
Form factor and Size
The weight of this Bluetooth speaker is around 70grams, which is quite small and compact.
Bluetooth Specification
This uses Bluetooth version 5.3 which is quite good, it has some decent length and reach..
Battery endurance
According to Edifier, this can last up to 8 hours of playback, but in my testing, it does not reach that mark. The closest I can get is around 3-4 hours in full volume, while in low volume, around 4-5 hours.
Charging
Honestly its quite acceptable for me. The charging output is around 1.5w to a maximum of 2w. In today's standard this is super slow and quite old..
