So far, the times that I have used it, it does very well. Mainly used for mountain biking.

I wish it had a little more grunt, but on the whole it is useful for getting above the crowd noise in an acoustically unfavourable setting.

I wasn't sure if I was willing to spend $30 for just two lenses but my options were a bit limited with the standerds I had set to myself. When I bought it i was just really hoping that the pictures came as good as the ones demonstrated. I received it in the mail very fast and I immediately went and tried it out. There is no doubt that this definantly has a significantly big difference between my actual camera. I have the iPhone 6s and the camera on this is ok not the best but not terrible and o absolutely love the finished look I get when I use the lense. I'd defiantly recommend this!

I bought a lot of headphones, and none of them really fit well in my ear. I have a small ear hole. These fit really well!
