has anyone compared them to the Sundara, which is a similar price, but without the blue mini?

I have the 2020 Sundara and I’d like to know if it’s worth both, i have t listened to samples yet, on paper it seems to be warmer than Sundara but I solve that with a tube preamp when I want things smother which isn’t alway. No track control is a pain though, I get that with my Sundara and btr5 in balance mode for casual listening. Trying to work out the value prop for Bluetooth without a bt dac amp say around house as btr5 or a ifi go blue is rather a tiny device and with a light 8 core platted cable isn’t such a bind really.
