OHO 4K Ultra HD Water Resistance Video Sunglasses, Sports Action Camera with Built-in Memory and Polarized UV400 Protection Safety Lenses,Unisex Sport Design

Very pleased with these glasses. I have had it for only two days and used it three times so far. The quality of the video and audio surpassed my expectations so much that I decided to leave this review. Even in very dim evening lights with the streetlights on, there is still legible recording, especially around streetlamps. Sound is crystal clear - the microphone even picked up faint music from my in-ear headphones. Daytime recording is as good as any standard digital camera. The battery did last 70 minutes during 3.8 miles walk and it was still recording when I stopped it. The material and quality of the glasses frame seems great. The dark lenses are not too dark, but good enough even when looking straight towards the sun. I will upload a short video that I trimmed directly from the recording made with these glasses. Also add a few screenshots from the evening walk. Overall fantastic pair of sunglasses. Highly recommended. Just a brief *update*: I had these now for 6 months with pretty much everyday use. Still great. The battery lasts about 60-70 minutes. One little nag is it does not have override capability. If I don't clear the memory card for a few days, it runs out of space in the middle of the walk and stops recording. I think it would be a really good feature if it had optional overwrite whereby the oldest file gets automatically deleted just before the memory card rans out of space.

Tested with a video. Connected to iPhone but it didn’t show up in files folder so plugged into laptop. Videos did transfer but they were corrupted so I couldn’t review them. There were another 6 videos as well which weren’t mine. Think they’ve been returned before. Do you want to send me a new pair. But don’t bother if I can’t transfer the files to an iPhone

Excellent. Playback is clear and especially the sound is clear. The size of memory denotes how long it can record. I will get a larger memory next time. First time I’ve given a 10 out of 10 review. Enjoy.

Was really impressed with the overall look and feel of the glasses. Build quality seems pretty good and the selection of lenses and accesories was really nice, however I did not receive the strap to secure the glasses to your head. I did not test the transition lenses out due to the decision to return the glasses. The features are pretty basic and straight forward and require you to edit a text file via a pc on the device storage to configure the settings. I only tested 4k30fps and 1080p60fps settings and although the resoloution was correct there is no real decernable difference in the quality or the fps when playing the video back via a pc. I also found the video on both resoloutions to be quite grainy and have pixel noise in the video. I also found that if you are in a fairly low light scenario with the glasses and there is a light source from a screen or elsewhere that the camera did not handle this well and and does not seem to have the firmware to focus and compensate for this so if you wanted to record a screen or light display you will just get an unfocused light source and will not be able to make out any images or designs. This final issue wich may only be a problem for some and on the Camo version due to its light colours and clear plastic used in the frame, which resulted in the flashing light from the video recording being visible through the frame on the front and side's of the nose bridge where the lights are mounted and I found this not only very anoying as it is visable in your peripheral vision while wearing the glasses but also eleminiates the descretionary factor and in any low light situations results in your nose and glases flashing red like a bulls eye right between your eyes.

I got these yesterday and so far they're phenomenal. Love the way they feel and controls are pretty good. When I went to extract the files from the storage I found 6 recordings already on it.5 of them were pure noise but the video I uploaded contains a man named Yanislam testing the glasses, even showing company emails. I chose to upload just to prove it happened, and I found it hilarious. Yanislam, if you find this review good job on testing the glasses, hope you don't get in trouble with the boss.

The 4k £119.99 most expensive model (sale price) version pros: Better resolution, meaning slightly sharper. The 4k version cons: 23 min battery life out of the claimed 30. (and in 1080p mode 47 mins, which is strange, maybe I got a bad unit) Very heavy 61g, advertised as 49g Large visible lens Chunky Shakey footage The image is very noisy, and trails the noise speckles with motion. Audio recording is very low. The 1080p £49.99 (sale price) pros: The battery lasts 1 hour and 28 mins. The image is much more stable, no major motion trail / lag. The lens is much smaller, so less noticeable. Although much heavier than the stated 35g, it was 47g which is fine, not too heavy like the 4k ones. Slimmer frame, comfier for the nose The audio recording is very clear quality and loud. £70 cheaper than the 4k, when it's next on sale might buy a second pair. This being said the 1080p version which comes with the spare lenses, this has been confirmed to be the same design as the 4k version meaning it's also heavy, so if you want the light weight model, you will want to get the very cheapest model. (£49.99 on sale, £89.99 regular price.) These glasses any model work as a nice addition to your dash cam, of course the benefit of the 4k is that it see's the numbers more clearly. I will upload a video at some other date.

Video and audio quality did not meet expectations, it's definitely not 4k. Additionally the glasses were far too small for my head and it's far too overpriced for what you get out of it.

Great footage

Buon prodotto qualità buona e giusta per il prezzo

Dålig kvalitet på bilden när man filmar. Skickade tillbaka dom.

Doesnt work. It turns on with a solid red light but wont do anything else. Wont connect to pc or record. Useless. Update Seller sent a replacement pair at no cost so I am revising my review to reflect the great customer service.

いいんじゃん、偏光サングラスじゃん。ロクビーも可能じゃん、写真可能じゃん、ドローン撮影も可能じゃん、目視の先にドローンじゃん。話聞いていてその時はわかるが！後で忘れても録画ムービーじゃん声も鮮明ありありじゃん。
