Aye, I have the NUX in ears so ‘wanted’ their wireless as its 5.8. A plus point is the charging case! The thing that pushed me to Blackstar was that the NUX only have a 2hr (ish) battery life before needing to be charged in the case. An Open Mic play at goes on longer much than that - and generally people use my gear even if I don’t play - and a lot of gigs are 2 1/2 hrs. Didn’t want to risk it.
I saw both at the Bass Show and another plus is the Blackstar fit in an old glasses case and take up a lot less space in the old leads bag (should we still be calling them that now?).
