I got the buds thanks to @coffeebaron The base was a bit weak and the sound not quite as good as my previous buds (Sony WF-1000x) but the first thing I did was fit some comply foam tips. As I expected this improved the base no end and with the EQ on dynamic I think I am completely happy with the sound. The sony's had dieing batteries and while livable they had the occasional drop outs from day 1. I had to cut the foam tips down a bit so that the buds fit into the case but I think they now make smaller ones for wireless airbuds if anyone is interested in purchasing them. Highly recommended.
