Overall Review: The fans I've been using are from 2014, and I knew they've gotten better. Until getting this guy, I had no idea how much better. At slow to medium speeds: I've heard more noise from waving a feather around. Absolutely perfect. Even at full speed, it is quieter than my old fans. Love it!

Pros: It moved air well enough at high at full speed. The lights are cool.

Cons: When at full speed produced so much noise it bothered my girlfriend in the other room. I didn't measure the sound, but would estimate it at over 40db. I finally disconnected it and am doing ok with my other fans while I order a new quieter one.

Overall Review: I'm going to kinda miss the lights.

Pros: Good sound quality, fits comfortably, pairs easily. This is the third one of these I've gotten... The first still works, but I order them for friends. Before this, I had another type of bluetooth... that was more expensive, and didn't have as good of sound quality. This is the first one I know of where you can talk while driving without the ambient car noise getting in the way.

Cons: None

Overall Review: I like the over the ear fit... and built in over the ear is way better than the little wire some come with. But if you don't want that, don't get this.

Comments: I bought and returned these faster than any other purchase I've made. I had to yell to be heard on the mic, and if any sound was coming in on the headset (not external speakers the headphone!) it could be heard as an echo by others. They kept asking me to "speak into the mic" and "turn down my speakers" meanwhile I was going hoarse and I could barely hear anything (though the sound on the headphones was turned all the way up). I can't image a 2 dollar set being worse, so if you are considering these save yourself the xx bucks.
