The teether between then is a spring. After 2 months the spring still rips then off my head 2-4 times a workout. Sometimes more. Hooks to ear but still a problem. Have tried to stretch outElectronically it all seems to work wellI have been trying to exercise with these on, now the right side has become loose, so instead of falling off 2-4 times a work out--it is over 10--to the point where I am going to try to return them or throw them away. This not only occurs during active exercise, but you can be walking on a tread mill, sitting with them on, and the "spring" will simply rip them off your head.

The instructions are almost vague. The light that tells you whether or not you need to charge it or if it is pairing for Bluetooth is SOOOOOO small. Need an eagle eye to see it. Then, charged them, didn't need to use them for 2 days, went to use and the battery was dead. So dead in fact that the little tiny light wouldn't register at first when I plugged them back in.

I think once I adjust them with the different earpieces I think they will stay in my ears better on my runs. They would be great for bike riding . When it says 3 feet is the operating range...they do mean it. I think the antenna is on the right side and if I have my I-pod in my left hand and extend my arm- it cuts out. But, with the natural bend in my arms while running they work great. It is easy to turn on and off and syncs very well. Charging is good as well.

Great sound. Very comfortable. Pick-up range is only about 20 feet.

Nice product, a little on the small side.

It works great. I can do many things while using the headphones to listen to music and chat with people and I don't have to worry about any cords being in the way. Its an awesome set of headphones.

Love them I have both 4 pairs so far.. I got them for my husband, kids and myself.

These headphones are wonderful. I was looking for Bluetooth earbuds and found these. I looked at different styles and decided I wanted ones that fit over my ears to make sure they stayed in place while running. It's so nice not to have to worry about a cord bouncing around while running anymore! It used to drive me insane having the cord jingling as I was running and having the armband for my phone. Now I have a slim waistband that my phone fits into and I don't have to deal with a tight band on my arm that sometimes slips off and a cord going to the earbuds. These were very easy to connect to my phone. You just push the button on the earbuds and it flashes, then it pops up on your phone under Bluetooth devices and click on it. The only downside, is I had seen some earbuds with play, next and back buttons on them and this one does not. I can't comment on battery life because I haven't used them for more than like an hour at a time. But I do often use them a couple times before recharging it.Disclaimer: I received this product at a discount or free in exchange for an honest and unbiased review of the product, based upon my own personal experience.
