I bought the speaker as an addition to my old Headrush FRFR112, and I will say that the old one is made of much better quality. On the old one the volume is 2 (!) times higher, the bass is juicy , this one has a dirty bass, and at high volume the sound is distorted. I tried changing the speakers - no difference, I noticed that the material of the case itself was different, in addition, in the Headrush FRFR112 (old) version there was a cotton wool spacer, in the Headrush FRFR112 MK 2 - nothing. Among the advantages - only bluetooth, and it’s not clear why it’s needed here. In general, I don’t recommend it. If possible, it’s better to take the old version.
