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

The media could not be loaded. 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.

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.

3rd pair ive biught now n returned its so dumb there is no audio and my previous pairs glitched on me too after a few weeks cheaply made clearly bow on the 4th pair they are over contrasted and AGAIN NO AUDIO DO NOT BUY

These shades look very nice and the picture and video quality is superb. I would recommend it for casual recreational use especially for outdoor people.

I took the glasses on a holiday break for an extensive 1 week test. Over 7 days I took 60 video shots ranging from 1 minute to 10 minutes. 29 of those videos had poor grainy picture of varying quality (see attached videos). If you record beyond 9 minutes you can feel the heat sinking into your upper cheek from the right frame where all the electronic functionality is located to record.The 4K, and 1440 resolution is wonderful when it works, anything below is pixelated including the 1080p which I was hoping to use most. I experienced no anti-shake when watching video back of me just walking, that I would be something anti-shake should be able to cope with besides being on skis or cycling.The lenses are quite quick and easy to change and they are all beautifully clear. The cleaning cloth that comes with it, is great. Charging the glasses is fairly quick and the battery life is as specified, you can store a lot of video and you can use a power pack to recharge even while you are recording and taking pictures which is excellent, if they could remove the grain issue.In order to change resolution, the date time stamp, etc, you need to plug the glasses into a PC or mac and amend a text file. Easy to do, but the instructions are not comprehensive. They forget to mention that you need to change the Update line at the top to Y, save the file, turn the glasses off, then on again. If doing this set the date and time at least 20 seconds ahead of current time to allow for the reset. Extracting the photos and videos is easy, just like working with an SD card or memory stick and the data transfer to my laptop was around 26Mb/s which is good for USB 2.0, pity it is not using current USB 3.0 technology.I do love these glasses, and I hope the video issues are a "personal experience" due to a defect and not a result of the manufacturer. I will be writing to the manufacturer to enquire, as this is the main reason customers will purchase this product.

The media could not be loaded. 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.

It arrived ahead of time and in excellent condition. Easy to use, good quality, would buy again. Highly recommend.

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 49gLarge visible lensChunkyShakey footageThe 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 noseThe 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.
