Great GoPro alternative
Works great for RC speed runs and bashing. Just the right size and compatible with GoPro mounts. I use it several times a week. Great picture quality if you ask me, but I’m a rookie in this game. Just BE careful inserting and removing the SIM card, you don’t want that spring inside to break. If it does, she’s a goner… unless you’re McGyver.

They never ask the important question...
Do they fit? Not me. I have fully expanded them and they still don't fit right. I don't know if I'm wrong or not but, sometimes, I don't think manufacturers always realize just how many of us have fat heads. If your head is larger than a medium, be prepared.The noise cancellation and sound quality are great, as are the battery life. (Blame Microsoft Editor grammar extension for the grammatical errors. I'm just tired of fighting with it.) The ear pieces are kind of hard to get oriented correctly to sit on the ears when you first put them on but are pretty comfortable after that...if they'd just come down a centimeter or so farther.I've been meaning to come back and add this for a while now but...Anyway, the most important thing here is my new 50" Samsung 4k TV does not see these BT headphones. Obviously can't use them for that. They still work with my 10 year old computer, though. I will add that I recently installed a new wireless network card from CUDY in this computer. It covers BT 5.0 so the headphones should be visible. Now, after 9 months of use, they've finally broken because they're too small. I mean the speakers still work. They just won't stay on my head because the framework is broken. I suspect, like anything else these days, that's by design. I'll let you know if I ever find a pair that fits and lasts. In the meantime, I'm still convinced the Power Locus brand of headphones work and fit the best but, in all honesty, even those don't always fit and will break from my big head. Still, when they do, I'm out less than half the price of these.

Q
77mm caps for 77mm filters? Am I correct? Step-up 67mm to 77mm should also work?!
A
Hello, thanks for reaching out! Yes, this 77mm K&F Concept lens filter cap is for a 77mm filter and will also fit one side of the step up ring with a 77mm filter size, unfortunately it will not fit the 67mm side of the step-up ring. Best regards 
Q
do i use a step up or step down to fit a 82mm filter to a 77mm lens? Thanks
A
... 
Q
Can the adapter rings also be combined with Step Up rings?
A
This is possible if you do not have a suitable adapter ring. However, care must be taken when reducing larger lens diameters because of possible vignetting.
