First off as you can see (only just see due to shoddy camera work
) a plastic construction complete with fully adjustable headband.
Front opening for phone.
Side to side lens adjustment.
Focus adjustment.
Phone holder adjustment.
My Samsung galaxy note 3 fits ok, but I did have to remove my flip cover, it would probably fit ok with the standard back on it.
It works great, resolution is not fantastic, but of course that is down to the phone not the headset. Headset wise, the nose piece could do with a bit of padding, but for £10 it is far better than I expected. There is enough adjustment in the lens positioning for me to be able to get it in focus without needing to wear my glasses, which is great. Also the two rear panels behind the phone slide off if you need to be able to allow the phones camera to see.
Now the bad points.
This particular model didn't come with the NFC magnetic control, which I thought it did, but that is just me not paying attention after looking at loads if different models, so there is no way to control the phone. I will be looking into one of those little Bluetooth controllers instead. Other than that I cannot fault it, remember it was only a tenner.
