I bought these headphones after a friend got them and talked about how much they liked them. I could hear my friend crystal clear on the voice chat as well so decided to give them a try. The headphones paired effortlessly with my iPad an the bluetooth works great. I can leave my iPad charging in my room and go anywhere in the house and still hear my music or podcasts clearly while working. My voice chat with my friend went really well and they could hear me crystal clear on our chat, which is great.Noise Cancellation: When I am working around the house, I can hear not only the music but the sounds around me when working. If noise cancellation is refering to blocking the outside soundscape then these have zero noise cancellation. If referring to excess sounds when using the microphone during a chat, then they work fabulous. During my gaming chat, I was multitasking and listening to music and videos on my phone. My friend heard my voice only and did not hear the sounds of my speaker phone, me eating, etc.Lights: The cat ears, ear pieces, and microphone all light up and the colors can be changed to your preference including cycling through the rainbow. The lights are cute however I cannot use the rainbow cycle as there is a noticeable buzzing sound in the headphone earpiece while that is occurring. When the headphones are set to a single color, there is no buzzing. I am sound sensitive, so that buzzing might not be an issue for non-sound-sensitive people. The microphone light was helpful in knowing where to reach if I wanted to adjust my mic position, but I also found it a little distracting since I had a glowing orb right under my eyes. I got used to it after a while and was able to ignore it.Comfort: I have found the headphones to be very comfortable and have worn them for half the day while doing chores around the house with no issues.Things I really like: Bluetooth range, retractable mic, color choices, easy switch locations for turning mic/etc on/off and changing volume and other settings, minimalization of outiside sounds into the retractable microphone when talking.Suggestions to company for future models: Resolve buzzing issue during color rotation, add an easy access switch to turn microphone light off while still having microphone work, consider a separate magnet pack so people can have more options to customize the ear pieces. Each color headset has a different cat design. It would be nice to be able to buy a separate pack with all the magnet designs so I can mix and match for more fun or replace lost or broken ear caps.Would I purchase this product again? Yes.
