Genki should be able to transfer voice through a bluetooth headset, just as if a headset was plugged in through the audio jack. Will be making a review about that soon!
This’ll make it a huge plus in taking your switch on the go. Playing something in depth like MH Generations on the go is a no brainer. Sure, it’s on the 3ds, but even that needs a wired headset to work around defaulting to speakers. To top it off, a 2 way multiple bluetooth device is just a bonus. If it works great universally I might pick up an adapter for use with my computer as well. Glad I supported and ordered this through their page.
