I have great headphones, so no need for something new, but if I had the need I would not get it cause of what you wrote above, @Al1885 !
I the end it’s all about having good sound, in my opinion.
Also, it’s 2.4Ghz - which is known to have challenges with WIFI signals.
I have Lekato MS-1 (also 2.4GHz) for my Headphones and Harley Benton AirBorne 5.8GHz Instrument for my bass. While not as covenient, as I need multiple devices, I can choose whatever component I use for any specific use case … and still have great head phones (for monitoring etc.).
Bottom line is: I would prefer the Boss Katana Go for a mobile use case, as I can use my own headphones AND it can be used as a poor man’s DAW.
