I'm not one that likes over the hear head phones (I'm an in-ear type of guy) but my only comparison to this style of headphones is the Beyerdynamic DT770 . I know you guys will probably crusify me for making this comparison, but it's my only reference point. I love these headphones and for $59.99 you can't go wrong. I've had these for 2 weeks and I love them.  They have great sound and I love the wireless capabilities. I wanted a headset I could use on my computer that didn't sound as terrible as the Logitech h390's. And the real truth is I wanted something to buy that felt like it had a ton of value.  This is it!  So check out my video as I talk more about it. 
 
In case you don't want to go through the video here are some quick bullet points.
 

1. Big ear cups that cover my entire ear. 
2. Doesn't get to hot and it's the Logitech g930 are the only over headphones I've used that I could wear for over an hour without discomfort
3. I love the external buttons. They're mappable for gaming, but I use them mostly for Spotify.
4. I get about 7 hours of battery life
5. Portable enough to stuff in my backpack without a case
6. Rugged will depend on time.

 
Here's my video, let me know if you have any questions. I'll probably do a follow up video review in 2-3 months.
 
Ryan's Review on Active Tech Review: https://youtu.be/HQLOy2u39Ao

I made a video review of the dt770 80ohm  quite sometime ago and was finally finished it. I got them on sale at Guitar Center for $179.99 , the deal was better than anywhere on the web so I jumped on it. When I auditioned them in-store, I was quite impressed.  I'm not much of an over the ear headphone person, but these were comfortable and sounded amazing.
 
For most of my listening life I've used only in-ear headphones because I live a very active and mobile lifestyle.  
 
As I began to use them more and more I noticed that they weren't providing me the "umph" I was looking for in certain kinds of music.  I also ran into so me issues with sibilance that was bothering my ears for female vocals. Not that it sounded bad, but quite the contrary, they sounded great!  But it seems that my ears are sensitive to that.  I used EQ'd it towards base and fixed many of my issues, in fact it sounded better for my tastes.
 
I've read great reviews about how noise cancellation and noise isolation was great.  They were, but not for noisy environments like a gym.
 
I've read so many great reviews about how it was like having 2 pillows on your head - amazing comfort and amazing sound.  I need more volume so i purchase the creative e1 portable headphone amp. 
 
And I'll tell you that it made such a huge difference.  Based on my experience, if you get these headphones, you need to purchase the this headphone amp.
 
It turns out my head and ears are either too big or too sensitive (probably both).  So it would hurt my temples.  I've asked the forums here and they suggested stretching it out, and it did help a bit, but not enough to justify keeping them.
 
Although my written review here seems a bit negative, my video review expresses my enthusiasm for them - however my issue is that, for my lifestyle, they weren't a proper fit.

I'm all about best use on a  budget for a specific person and lifestyle.  In my case, the Jaybird Bluebud X's were fantastic.  You can check out my review on head fi here, but I also have an older "real time review" video of them here.
 
How does someone that loves high end audio find themselves buying cheap $30 wireless earbuds?
 
My listening habits consist of 75-85% spoken word.  Audiobooks, podcasts and youtube videos.  The other 15-25% is music which is done during writing, editing video and working out. I needed to justify a reason to buy some high-end audio.  So the only way I could justify it was to sell my jaybird BBX (I'm budget conscious or at least I try to be).  When I saw this for $29.99 on amazon I figured I'd give it a try.  They arrived and they did exactly what I needed them to do.  I also made a video review of these here.
 
I view these as the best disposable headphones ever.
 
For working out (I'm a powerlifter) they are terrific.  The freedom, feel and use is the same as the BBX's but at less than 1/4th the price.
 
Sound quality is crappy is slightly better than FM radio sounding.  As a primary set to listen to music they are can be great for teens or someone who's looking for an inexpensive wireless solution.  Perfect for active lifestyle.  You really can't go wrong with these if you use them like I do, a great back up pair or spoken word headset.
 
Call quality is as you would expect, NOT better than having the phone to your head.  What's nice is that you can keep one in one ear and place the headset with the mic close to your mouth.  

Experience with Customer Service
 
In case you want to see a video review, search youtube for "Jaybird Real time Review" and my video should be first on the list.
 
I'm going to start by saying that Jaybird as a company has fantastic customer service. I've ran into problems with my headphones and got replacments within a reasonable amount of time.  They're quick to respond and I can't say enough of how awesome I've been treated.
 
I bought these back in September 2013 and have had these as my go to since Last week Janruary 2015. This is the longest I've ever owned a set of high quality headphones and I love them.  I'm having some sellers remorse and want them back. There's a good chance I will own these again or the next version of these phones in the future.
 
I speak so highly of their customer service because they have a very liberal replacment policy.  It seems that they really care about maintaining a strong brand.  I've been out of warranty but have still gotten replacements.  I guess technically, they were in warranty.  They have a life time sweat proof warranty. So if the headphones were to fail because of sweat they will replace them, just as long as you have proof of purchase. So if you buy these, buy them from authorized reseller.
 
Over the course of 16 months these headphones have failed a total of 4 times.  You would think that after it failed I would be upset, but the reason why i'm not is that there is no other set of wireless earbuds that sound this good and have strong customer service.  The first time they failed, on side gave out and i just exchanged it at best buy ( bought it from best buy using an amazon price match).  Second & third time they failed and they stopped charging.  Sent them in and got a brand new one. The 4th time I sent them in I had a pairing issue that was annoying. 
 
When I got the new ones back I decided that I wanted a different set up. 
 
Sound Quality
 
By far the best sounding. Base is rich and warm.  Maybe my expectation were low, but I was blown away that these were wired headphones.  Keep in mind the reason why I was blown away was because I was using apple earpods at the time.  Mids and highs are clear and compliment the base.  Doesn't sound muddy. They are not better than wired headphones.  As I type this review I'm listening to some daft punk on my recently purchased Beyerdynamic DT 770 Pro's and the detail I'm hearing is something you won't hear.
 
During the time I had to send the Jaybirds for repair, I tried the Back Beat Go 2 headphones and it was dissapointing how poor they sounded.  Jaybird has done something special to make their sound good. It's adequite and the quality you lose from wired headphones is worth having now wires based on my use.
 
Comfort
 
I've watched some videos on the Jaybirds and the main complain I hear is the fit.  You have to fiddle around with the right fit.  The best fit for me was to wear them upsidedown so that I could have the cable wrap around my ear and hug my head.  I did experience some discomfort with my ears because of the "wings" that are used to secure them in when wearing them for over an hour.  Typically, these can be difficult to wear for more than 2 hours.
 
Best Use & Final Opinion
 
I'm a personal trainer and work in a commerical gym.  I have gym bags and move stuff around alot. I'm very active.  These headphones are perfect for someone that wants the best sound  in a wireless earbud.  When I do buy these again I will probably get the Comply Foam tips or find a double or triple flange tip to improve the seal. These are great for me because I can keep one in my ear and one out. It's easy to stuff them in my pocket or rest around my neck.
 
Closing thoughts
 
Figuring out the fit is cumersome and can be annoying.  Take the time to try to figure it out so you can get it work for you.  Be patient and figure out the right set up.  Also, see if you can find better aftermarket tips.  After trying a minimum of 3 fit combinations and you still can't get it to work for you, return them.
