they've been there for ages. At some point I wondered why does Jolla bother with newest midranger every time since for the same money one can get few moths old flagship which is better device.
Design is better on XA2 IMO, and there's 3.5mm jack but I paid my XZ2 300€ (with free XM2 headphones) at a time when XA2 was retailing for more than that.
