I was not sure if these would work or not, but I wanted something to play music while riding. I am really pleased and excited by the results. I use these only for music and cannot vouch for the phone part, but I am sure it works well for that as well. I have a full face helmet and listen to music off my iphone7 via Amazon Prime. Some have questioned the sound level of these, but you have to be sure the volume on your phone is actually turned up too. I've not had any issues with sound at all with these and could actually turn the notch down a level or to. I have found that there is a difference in sound in new music and old music. Jim Croce music is harder to hear then John Anderson music. I assume the recording sound level was different. With streaming music from a Prime station I've had not problems hearing riding at speeds up to 60 MPH. It is important to put them at the correct ear level too because as some have mentioned they are slightly thick. I had to adjust where they were in the helmet a couple of times to make them feel good.They were easy to install and quick to sync with bluetooth on phone. For 20 bucks... these are a steal!UPDATE.I came back on here to express how much I love this item. I use them every time I ride. The sound is plently loud, at times I want to turn down, and I can also hear my engine. I cannot imagine anyone not liking this item.
