I have a pair of 3800s that in hindsight may not have been what I should have purchased (very problematic remotes that lose their sync regularly). I also regret not being able to use my universal IR remotes. I'm thinking of selling my almost new 3800s at online auction and buying a pair of 3900s.
From what I can tell - they are very similar units...?
I would lose the built in microphones for audio search (could still do this via mobile ap)
I would have to have the unit in visible line of site as with any traditional IR controlled device
I would be able to use a single universal IR remote for all devices including the 3900
Am I missing anything?
