Management: A native remote control is good for navigating the menu, it’s not enough for the Internet. I use either a wireless keyboard or a Fly Air mouse. The keyboard is good for typing, shortcut keys, the touchpad. The mouse is also good, you need to get used to the current gyroscope, but infuriates when in the dark instead of the volume you press the home key (buttons next to it) and fly out of an Internet or a movie.
Sound. I listen through the optics to JBL active acoustics 5.1, I bought 10-15 years ago, for the room 18m power for my eyes. If not a film, then the Tronsmart T6 is also enough, I attached a bottle cage to the rack, it sits securely in it. I make sound through the cord from the headphone output to the AUX Tronsmarta, or through bluetooth, you can put a speaker under your head or next to it, the normul bangs.
3D. Viewing 3D on a reflector is good, brightness is enough, but on a sliding screen it’s a bit dark. Due to the screen size on a 3D projector, it’s fine, I have a lesser effect on TV 47 ”, as you look out the window. There are two glasses for viewing, the first ones The quality is good, but the glasses are not enough. Another of the minuses is that the left / right switch button is on the nose and it’s quite tight, it’s difficult to switch with one hand and the second charging socket is under this button, you can’t charge and watch a movie, if necessary. But the second ones comfortable glasses, switch button for d To the side of the phone, charging (mini usb, which surprised) in the same place, you can connect a power bank and watch if an Akka suddenly sits. But the glasses came with a marriage, something with a color, faces in a negative, the colors were burned out. I wrote to the seller, sent photo to him, he immediately returned the money 100%, for which many thanks to him!) And let the glasses be, a freebie, if you don’t look closely at the defect, you can watch!
That's probably all, the projector is 99% satisfied with everything good and peace!)
