Bluetooth Headphones, KOOWIEN Bluetooth 4.1 Stereo Wireless Earphones Sports Earbuds Headset for Gym Running Exercise with Mic(8 Hours Play Time, IPX4 Sweatproof, Secure Ear Hooks Design)- Black

The connecting cord is long and gets caught on other stuff. The battery life on standby is atrocious. The battery life listening on one day seemed to be about 6 hours. Can't be exact as it gets turned on & off throughout the work day. The ear pieces are big. If you think the picture makes them look big, it is not an illusion. The instructions for how to use the controls are poor (inadequate). Finally, I find the ear pieces uncomfortable.

Poorly designed product. Pairs properly the first time, no issues. However, if you want to re-pair it with a new phone, it will not work. Holding down the power button for 5-10 seconds when powering it up should move it into pairing mode (blue-red flashing lights). It will not do that. Tried holding the button down longer with powering on. Tried to hold it down when powering off. Tried combination of power button with volume up and volume down button. Nothing works. The device turns on, and immediately says CONNECTED even though my phone is turned off.Bad design.

The treble is too high compared to the bass. These do have good bass, but the treble is really loud comparatively, so if the bass is big, the treble is probably too loud for you to comfortably listen to. I wish they'd dial down the treble and up the bass with these. They fit comfortably, though.

wouldn't hold a charge, sometimes it just decided it wasn't going to turn on even with a full battery charge (probably a bad switch problem ) or, if it did come on, wouldn't connect. Got frustrated and tossed them in the trash.

I would have given a 5-star a few months ago but a piece popped-off and then are now held together with duct tape. With that said, they work great even with duct tape. Seemless connection to my Iphone, good sound, and comfortable.

Love these! Work great with my iPhone 5s and Apple Watch, so much better than having the wire flapping around while I'm working out!

Very staticky and cuts off when I look down when I'm mowing.....if those two things didn't happen the sound quality is good and they would get 5 stars

Great sound!!! Normal use includes running, and commuting to work. I would recommend these to those of you who are on a budget and wondering what to choose. These are great!!! I was not paid for this review.
