I got these as a gift and they are horrible! They fit great and I love the concept of them. If you just want them for music I would recommend them. But for tracking purposes...don't even bother! They don't pick up full miles (if you only do a half a mile, it won't register it), half the time it won't even pick up all of my miles (if I do a 6 mile run it may only pick up 4 of them), the lap time is WAY off. The timing for my miles is what I was looking forward to the most. However it is way off. I contacted Jabra to try to fix the issue and I have 3 different case numbers and still no solution. I just got an email from them yesterday telling me to use it with another device or phone. Well I don't have that option so I'll be returning this product. I'm tired of trying to get them to help me!! If I could have given this 0 stars I would have!
I love how comfortable these feel when you first put them on. It almost feels like you aren't wearing anything. However, my issue with them was they ride up where they don't belong! I wore a pair to work and was so uncomfortable all day! I contemplated taking them off. But I thought that would be more uncomfortable. I really wish they didn't have this issue, otherwise I would have switched all my undergarments to this!!
I've used an entire tube of this. I used the same toothpaste for years and never had any problems. I bought this one and I have a cavity. I haven't had a cavity in more than 5 years. I don't eat a lot of junk food so I know that wasn't the issue. I won't use this again and don't recommend it.
