Éronnée data sheet
The data sheet claims a frequency down to 30 Hz, which is technically impossible given the narrow width of the loudspeakers (edifier claims 180 Hz). These low frequencies are generally achievable with quality subwoofers with a woofer at least 16cm in diameter.
As far as the sound is concerned, the quality is average, with a dominant mid-range (very unpleasant when listening to voices: podcasts, youtube conferences, etc.), the bass is absent and the treble is a little recessed, giving a sensation of an audio 'halo'.
The usb and jack cables are on the right-hand speaker, and the wire linking each speaker measures around 95cm. All the cables are fixed.
In short, this is a kit that will help you out but will be less balanced than some entry-level bluetooth speakers.
ps: I've had these for 3 years.
