Koncen X11 Bluetooth 4.1 Wireless Sports Headset for Smartphone – Black & Green

As an audio enthusiast and runner, I've owned over 10 sets of wired and bluetooth headphones and feel I should point out some of the details with this product that aren't in the description, as well as my opinion after running with them for a couple dozen miles.Physical fit: Though they do look somewhat awkward while in use, they stay in place fairly well. I find myself only adjusting them maybe once or twice during a longer run. I do like how they keep the top of the ear free for sunglasses, cap, etc. Unfortunately, if you run in the cold, these probably will not do. They stick out too far to put any kind of muffs or thermal around, except for maybe a loose hoodie. The rubber tips come in three sizes, but be warned, they are firm and tough to change. You might punch the little debris screen inward trying to change them unless you are patient and careful. I was worried the little hook would be uncomfortable in the ear. It felt a touch unusual at first, but I quickly got used to it and it doesn't hurt over time. If you have very sensitive ears though, this might be an issue. Oh, and a side note, each side has a small L and R where the cable leaves the plastic part. These are printed in reverse. You will go nuts trying to put the L one in your R ear... it won't work right. Note that the rubber tips do have a tendency to block out ambient noise, which can be either good or bad depending on your workout, or if you run where it might be better to hear possible traffic.Operation: Unlike the supporting piece of paper says, there are only 2 buttons on this device. One button provides power on/off, pairing, pause, play, answer call, redial, and hang up. Yep, all from one button. The other button is skip and volume. This is where the product loses a star for sure. There is only skip track ahead. There is no way to repeat track, only skip forward. You hold it down two seconds to skip. If you touch it quickly, it turns the volume up to the next level. If you want to turn the volume down, you have to keep making it louder until you get to max volume, then tap again and it cycles to minimum volume, and starts going up again. In other words, to turn the volume down one "notch", you will have to press this button 7 times and subject your ears to max volume somewhere during this process. Long pressing the button for 2 seconds to perform a skip requires holding the other side of the unit with the thumb, in my experience, which is a little cumbersome while running, but I'm getting used to it. The LEDs on the top to indicate if it is on or off are way too small. You have to hold it just right and look deep into a pin-prick hole to see if the unit is on.Sound: The quality is as expected for this price point. Nothing awesome, but not horrible either. People seem focused on the bass, but that is really not going to matter. The only way to get any bass out of these is to put them in at a perfect angle, then to never move. When active, the ear "hook" doesn't have the strength to brace it against your ear canal to keep a tighter fit for bass transmission. They don't fall off, but they won't stay as close as necessary for emphasizing bass. The sound quality is below that of the Arriva Leo headphones, or the Motorola S305. It is equal to the Rokit Boost Swage, though those are over-the-ear.When I run with them, yes, I notice them but they are not uncomfortable. The battery life is good so far. I will continue to use them in warmer weather. If you turn your head near 90 degrees, they will move enough to have to potentially adjust them. I have not used the tiny shirt clip that comes with them. This allows you to clip the loose cable loop onto the edge of your neckline somewhere. It is very small and someday I might try it out, but I haven't felt the need.I hope this review is helpful.

I just received this headphones, nope not being paid by Amazon. And the honest truth is that they are great. I would expect to pay $60 at the min for these. They cancel noise exceptionally well, I've been using them as I work out and I'm a constant sweater, and the Bluetooth services well as long as you keep the phone in close proximity. Also, the case and other earbud sizes is a nice bonus. Decided to wait a month to post a review bc I wanted to give an unbiased opinion with some of the mixed reviews on the durability. Will be ordering these again for a gift. Oh and tip for whoever's new to these, hold the bigger button for 5sec to sync to your phone. It's not in the instructions and I had to inquire myself on it.👍🏼

We've been researching the best Bluetooth ear buds and I purchased these while my husband purchased beats. We were amazed with the sound cancellation on these compared to the beats. Also, the sound quality is much better than I thought it would be... They are better than any earbuds I have owned. They fit comfortably on both of us and do not fall out easily. It comes with a very nice case too!

This product is mediocre. The sound quality is great once it is connected, but the connectivity is very poor (choppy). Based on connectivity with iPod, then an iPhone, then the Apple MacBook Pro, it had duplicate results all around. Maybe 4-6 seconds of sound all clear, balanced with 3-10 seconds of choppy sound, regardless of remaining power.Synchronization is smooth, device is easily discovered. The audio quality is decent when it works every 5 or so seconds, the remaining connectivity is all broken up.

I bought these a while back and they are not what I was expecting but I learned a valuable lesson that sometimes things that are a great deal don't always work as intended, thus they are garbage. Anyways, I connected these to my Samsung galaxy and quickly found that range on these head phones was so small that I could not even put my phone in my pocket without the audio droping. After much experimentation the only way to get the audio to not be scratchy or drop was to place the phone uncomfortably close to the headphones. I guess I got what I paid for and I now use Jaybirds.

These headphones fit great in my ears and connect to two devices at once. I can easily switch between the two. Easy to operate and sound great.Update: 9 months in and I still love these headphones. I'd recommend them to anybody that jogs or works out. They do not fall out of my ears. They do get a little slippery if I'm pouring sweat, but that only happens when I'm watching Cops or Breaking Bad. So, do your self a solid and pick up a pair of these majestic ear ticklers.

These worked great for a few months, but all of the sudden, I can't get them to pair with my phone. They don't show up as an option at all, regardless of what buttons I push. I've tried this on 3 cell phones and my laptop and nothing, and the instructions that are given by this company on the product page are bogus. The instructions they give with the earbuds are wrong, too, citing icons on buttons that don't exist and colored lights that aren't there or are a different color. Don't waste your time.

Ordered these because they got good reviews... My boyfriend even has a pair from the same company that works very well. I'm so disappointed. The charge light turned blue even though they were not fully charged. And they are glitchy. The voice says they are connected, then says it again but sounds crazy like a malfunctioning robot. Then I try to use them, I get maybe 2 feet away and they start to cut out. I will be returning these.
