"Great training partner!"4.5 starson by MNRLrunner
Pros: I train 5 days a week and have been using these almost 2 weeks at the gym and on a few runs. They have done basically everything jaybird claims they would. The fit is good and the bluetooth signal and sound quality is awesome. Battery life is great.
Cons: I have yet to run the battery fully out and do a complete recharge to really see what they will do. I did however go 3 days this week with out a charge and spend about 2 hours with each training session. The dual fit took a little bit to dial in.
Summary: I am an avid outdoors and fitness participant and have been using wired earphones for years until the past few months. I have tried a few other wireless brands, but have not been satisfied thus far. With that said, in the 2 weeks I have had these they are the best I have owned and I am not planning on trying anything else. So far, so good!
