Love/hate with this product.For all the positives it has, I ended up returning it because of its' construction.Pros:- great connectivity, battery life and comfort.  The earbuds fit well and the sound is very clear.  It also holds a charge through a solid 5 hours a day.  I would charge it at the end of every day, so not sure how much longer it would last if I kept using it.Cons:- Although it is very comfortable and easy to wear during active runs and gym sessions, it just feels flimsy to me.The little earbuds are supposed to be held onto the neckband with little magnets.  These magnets are far too weak and barely hold them in when they are stationary.  They are also not the easiest to fit in place while the neckband is still around your neck.If you do manage to fit them in, the slightest head movement causes them to fall out.This is not only frustrating, but with them just dangling there, they easily got caught on my jacket, shoulder strap of my purse and scarf.It was an accident waiting to happen and I just knew they'd get torn off one day soon.Another concern was how they'd hold up being toted around in bag.  If you don't want to walk around with them hanging around your neck, there's really no easy way to transport them.  I'd wear them on the train to listen to music, but didn't want to leave them on once I got to work.  I'd put them in my bag, but then had to wrestle with a tangle when I retrieved them.Overall very disappointed because although user unfriendly, the sound and comfort of these were great.  If you're just going to be using them at home and not taking them with you, they will suffice.  A bit pricey for being limited like that though.  That's why I ultimately returned them.
