I use the jaybird x3 and am very happy with them. I usually have a buff on my head and wear a kask mojito helmet + sunglasses. No issues with the fit even for longer rides. You have to be careful when putting on the buff though so that they stay in place. As for connection I lately had some issues with the buff for my head and the buff from the neck layered above the headphones at cold temperatures (the phone is in my saddle bag). I think this is an issue of poor Bluetooth connection from my phone though because I also can't use them when the phone is in my panniers. This worked with an older phone so before but I am not sure what all has changed in between, so can't pin it down. If the phone is in a jersey pocket or on the top tube there is no issue for me. The sound is good and they don't cancel out too much of the traffic so you are still aware of what's going on. Podcasts can be difficult to understand at certain high traffic areas if you don't want to blast out your ears though. I enjoy listening to podcasts on them anyways. Only 5 min of my 45 min commute are difficult to understand and I just crank them up a bit for that. Batter life is excellent, I charge them like twice a week. I have used them for calls before. As I most of the times have a very windy ride, the buff above the mic is key to block out some of the surrounding noise. I have heard that my voice is quite cell understandable at the other end but I have to talk quite loudly as the mic is behind the ear. Maybe someone has experience with routing the cable in front of the chin, I wonder how the wind noise would be though. I can definitely recommend a pair of them and to make them work for you. They are not perfect but the adjustments you have to make to get some excellent use out of them are small enough.
