One more thing w.r.t. the Eris E4.5 before I buy a pair, I've read about user experiences that state these monitors seem pretty sensitive for nearby cellphones, radio, nearby switching of illumination etc.
It's all hearsay, so no idea if this is really a vulnerability of the design, or extreme user conditions.
If it's the former, possibly it has been addressed in the design meanwhile, for later production runs ?
Thanks!
