Pros Good sound, good blue tooth, light weight
Cons Dependability. Lousy warranty policy! $169 for disposable earphones
Summary I truly loved these when I got them. Best blue tooth earphones I had seen. Then they completely died on me in month three. Jaybird replaced them and I was happy again - until 4 months later the new set died. Jaybird policy says the warranty on the replaced earphones is only 3 months! I had two sets die inside the original warranty and they refuse to replace the second pair. I can only assume they know that their product only lasts 3 months at a time. These turned out to be the most expensive disposable earphones ever.
Pros Fit, depending on ear size, mine fits snug and securely.
Sound, good bass and treble provided you're sealed in properly
Size, compact and easy to store with carrying case.
Cons Price for some but worth the value for me.
Summary If you're an audiophile and looking at blue tooth, you're already barking up the wrong tree. As far as blue tooth headphones go, this is by far the best I've used. I've used Sony, Motorola and Plantronics and by far from the sound quality to the fit, these have been perfect.
My average day is 1.5 hours at the gym in the morning, 1 hour commute to and from work and as the Summer comes along I'll be using this even more. No problems yet.
The issues with ear buds have always been "fit". I like yhe wings that they created because it helps me find a complete sealed fit for true bass and treble.
I recommend these...I really do.
Pros Sound quality, durability
Cons Fit, comfort, price
Summary I have been looking for a bluetooth headset that I could wear on long runs and during weightlifting, but would also allow me to answer occasional calls while working out. I use a separate headset (LG Tone+) for other usage (office, car, airplane).
I read numerous reviews, from both professionals and end-users, from this site and others prior to purchasing the BlueBuds X. Based on those reviews, I knew that my satisfaction with this product would depend almost entirely on my ability to get a good fit. That prediction proved true.
After 3 weeks of using the BlueBuds X daily for running and lifting, I never could get a good fit. I only tried the under-ear mode, because I need to use the microphone occassionally. The BlueBuds did not completely fall out of my ears, but they never had a tight fit and kept getting looser during exercise. I was constantly pushing them back in my ears. The loose fit allowed too much noise, which was especially annoying at the fitness center. My cheap SkullCandy wired earbuds provide a much tighter fit, but wired earbuds are a pain to use with my Lifeproof case. Since I went past the 15-day return period from the retailer, I'm stuck with Bluebuds, which I will try to sell.
Considering the BlueBuds to be a sunk cost, I then purchased the Motorola S11-Flex HD headset. After using the S11 for a week of daily workouts, I am completely satisfied with the S11.
If you can get a good fit, you will likely be very pleased. If you do not get a good fit, you will be dissatisfied and have an expensive, useless headset on your hands. Unfortunately, there's no way to test the fit without buying the headset.
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!
