I am delighted with my purchase. Some of the included instruction are vague but when deciphered with Pyle CSR's this camera performs to function and for the price is a very good alternative to more expensive cameras.

The Yi 4K Action Camera is performing very well; especially after I upgraded my firmware to version 1.33. The new stability feature has helped greatly with the Fish Eye distortion issues. One disappointment to me an engineer who uses Windows extensively is the total lack ofa Windows 10 based app that will allow me either to Wi Fi connect and upload images from the camera to my PC's or make use of the USB port which so far seems only useful for charging the battery???I also own a GoPro Hero5 Black. GoPro provides a nice Windows app that automatically uploads images from their camera to my Photos folder. This is a basic tool that I would have expected to exist. I have used the YI Action app on my Android phone to take a few pictures. The Android based app is robust but still, Windows has a enormous audience. Windows products include their Nokia phone and tablets clearly these are targets for an app. Overall I am pleased with Xiaomi's product and with increasing firmware updates the device will shine. One addition could be speech commands which are very powerful on my GoPro. These comments are directed to the YI team.

Boy great set I am impressed. Not cheap like I have heard others say. BUY IT!

I bought these to pair with my laptop so I could do Microsoft Team meetings from my home. I initially had issues where the microphone would stop working after 15 minutes - but Bose just released an updated firmware for the headphones and all of my issues are gone. Now I have been on several hour long calls - no audio or microphone issues at all!!!I have my home office currently setup in a converted workshop - so I have a heater hanging from the ceiling that is quite loud. I am amazed that these headphones can cancel out the noise of the heater - and what is more amazing is that the people I am talking to cannot hear it either - they only hear my voice. I gotta say, these are amazing.I have the headphones also paired with my android phone - and the headphones are able to switch back and forth between devices seamlessly. If I am listening to music from my computer, a phone call on my cell phone will immediately switch the audio to my phone for the call, then after the call ends, I go right back to the music on my computer.Overall - 5/5! Very Impressed!

I purchased this camera for my back packing trips and compared to the gopro I am HIGHLY satisfied and ready to make some amazing videos. I love the voice commend and the sleek design. I would totally recommend this product to a friend.

Keeping in mind that these headphones are less than $20, they are very good. I wear them when on my computer so that I don't bother the family. They are on ear headphones, but still reduce outside noise to the point where I can't hear my wife in the next room (oops...). I am not an audiophile, but the quality is good enough for me. For the price, I think they are one of the best pairs on the market.

So many people have been coming ang going in my home. Some welcomed, some not. The moving company I hired managed to "lose" way too many things that were mine. Neighbors have tried to help me get settled in, but because of certain missing items, I suspect they may have had sticky fingers. A word to the wise is - always have a nanny cam in place and ready to use, just in case. This isn't the first nanny cam I have used, and I am sure it won't be the last. They are cheap, easy to use, and as soon as "guests" know they are on "Candid Camera", they will be on their best behavior.

For the price its offering go for it. The treble parts sounds a bit weak but as soon as I put a song it sounds very full and very can hear all mid and high very well. The Bass is not that strong that goes for my Sony headphones are king. These sound good for a casual day but I am going to start a new job that these headphones are required and hit the jackpot here in Amazon.
