Simple Video Display Glasses. Type-C Input, Easy Connect to iPhone 15 Directly,Plug and Play, no Need APP.Not VR HMD. Without Battery, Light Weight (Bigeyes H5 USB-C)

Worked ok, but returned it as it will not fit over glasses.

Delivered today. It's simple to set up, but just didn't work. Tech Support is in China with no number for USA.

I bought these strictly because they looked like a cool gadget. They are. It takes a little fiddling with but I'm a happy little technogadget fan.

I gave this a test drive on a few devices. My thoughts:Overall, it's very responsive and the resolution is good. These work only without glasses, however, the lenses can be adjusted to accommodate what seems to be most visions. The lenses are a bit challenging to turn and calibrate, but it can be done with relative ease.One thing I don't like is that if you're like me, you move around a lot if you work, and it's hard to concentrate on the image if you're moving your head. I wouldn't recommend these for exercise, but try it out anyway.The strap is adjustable and should fit most heads securely.Other thoughts about key uses:1. This works wonderfully with a mobile phone, but I highly recommend trying to use it with a little USB-C hub. The reason for this is that without access to your phone, you won't know where to click easily unless you have perfect muscle memory. A USB hub can give you a mouse and keyboard, so you can do mobile work privately on the go. Not ideal, but if privacy is important, I suggest this. Additionally, a hub will allow you to charge your phone and keep the glasses powered on.2. This works with a PC that has video-out capabilities via USB-C. This can be used as a duplicate monitor (ideal) or as an additional monitor (extend desktop). I personally had trouble focusing on work using it (Excel), however, certain work can likely be enhanced by these (visual work, work that requires privacy).3. This is probably ideal for watching movies and playing console-type games with a physical controller you don't need to look at. I found just laying around watching some TV shows to work rather well.

This is a very stripped down and simple head mounted display. It has very little in the way of features, but what it does it does well. I can see this being a good way to watch TV in bed or on a plane.The goggles are extremely light and they're very easy to put on and take off. They sit very comfortably.The distance from the eye to the display is a bit too long. Unlike VR goggles, there is a very obvious black border around the 16:9 display, so it kind of gives the effect of looking at a TV hanging on a black wall in front of you. Unfortunately the corners of the display aren't visible unless you smash the gasket into your face to reduce the distance from your eyes to the actual screen.If you normally wear glasses, you will not need to wear glasses to use these goggles as each eye lens is equipped with an independent diopter. The diopters are even marked with the diopter values so if you happen to know your prescription you can just turn the dials to match it. Unfortunately the diopters can only be operated by turning the dial located right where the lenses are, so adjusting them as you're looking through them (as you need to if you don't remember your prescription) is very difficult to do.There are sliders located on the top of the goggles for adjusting pupilary distance.While it's not perfect, when you get the pupilary distance and diopters set properly, you're treated to a very crisp and clear screen.I tried four separate devices with these.The iPhone 15 gave a very clear image, but there was an additional border as I don't believe the phone will output the native 1280x720 resilution of the screen. I had a little trouble because the supplied USB-C cable had a plug end that was just barely too fat to fit through the gap in my phone case. The image kept cutting in and out until I just took my phone out of my case. When the iPhone is outputting video via USB-C, whatever that video is remains on the phone screen too, so you can't use these for private viewing - like say you were laying in bed and didn't want to disturb your spouse with what you're watching - the screen of your phone is still going to be glowing and flashing. Also, it's pretty much impossible to use the touch controls on the iPhone without looking at the phone screen itself, so any pausing, fast forwarding, browsing or whatever either has to be done blind, or you're going to be taking the goggles off every time you want to do something. If iPhone is your primary use case, keep in mind, you will probably not be able to use the full resolution of the goggles, and you may need to get a different phone case or a different USB-C cable, the phone screen will still be showing whatever you're looking at, and you won't really be able to navigate or control what you're seeing without taking the goggles off and looking at the phone.Using a Windows PC with a USB-C port wired to the video card was very straightforward. Windows immediately recognized the display and set it up. The display is crisp enough that I had no trouble typing, browsing and doing normal PC functions. These passed several of the Blur Busters tests for image retention, frame rate and ghosting. They held up very well.I also tried a Nintendo Switch, and a Modretro Chromatic - both of which have unpowered USB-C video, and neither of which worked because these goggles require the USB connection to provide both power AND video. I imagine if I used an external dock that provided power it would have worked find on either but did not take my testing that far.There are also devices available which can convert HDMI output to USB-C input which would ostensibly give these goggles the capability of viewing HDMI sources, but these adapters are $25-$30, and it's very easy to get them confused with the much more common USB-C to HDMI adapters which would definitely NOT work with this.The goggles don't come with any kind of carrying case to keep dust off them when they're not in use or to keep the cord and headphones with them when they're being moved.Pros:- Lightweight- Comfortable- Has independent diopters so you don't need to wear your glasses- Has independent adjustments for pupil distance- Display is very responsive and clear- Only one wire for both power and videoCons:- Only video source is USB-C- Diopters cannot be accessed from "outside" the headset- Won't work with unpowered sources- Distance from eye to display is too longNeutral:- No carrying case or bag or anything- No lense coversIn conclusion, these are very capable 2D goggles that provide a clear image once you've gone through the trouble of adjusting them. The iPhone use case is sub optimal because you won't be able to use the full screen resolution. Because it only accepts video over USB-C AND has to be powered by the same connection, your options for video sources are extremely limited unless you want to spend extra on adapters. They could made this a lot more useful by including a mini or micro HDMI port as an option. If you're looking for the novelty of wearing a TV on your face these are a fairly cost effective way to do that. Using them with a PC or a laptop that can ouput video over USB-C is pretty much the only practical use case (iPhone is just too unweildy) so don't expect to go around untethered. It's hard to recommend these unconditionally, but they're okay for what they claim to be.
