Really good! Great alternative to action sport cameras. Good battery development and sharp image in 4K. Very nice!

tube problema la carcasa de la camara entra muy ajustada y me rompio el borde de la camara donde esta la marca. el borde es muy fino y el plastico no es resistente se rompio muy facil a sacarla de la carcasa

I am not sure what high end over the ear headphones sound like. I’m also not sure what cheap headphones sound like. But I am sure these headphones sound great to my untrained ears. Bluetooth works good. But I have not figured out to disconnect from a source and contact to a different source without turning the first source off. But all in all. Pretty dang good.

These work great and are perfect if you have multiple devices because you only need the one headset. I can pair both my personal and work phone, or switch up to my computer (using the optional bluetooth adapter) to use with Lync. It will switch back and forth as needed, but (obviously) can't connect to both at the same time. The noise reduction is excellent as well. I can talk to people on the phone while in a data center and they can hear me just fine.

I have been using this filter primarily to get rid of glare in my webcam setup so my requirements may not be as stringent as for more classical applications. Compared to a Nikon filter I have (of a different size, for a different lens), the polarization effect is a bit lower on the Tiffen, and it also lets through more light. Contrary to some comparisons I've seen online though, the Tiffen for me produces a warmer picture than the Nikon.
