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. ### ⭐⭐⭐⭐⭐ Truthfully Great *by A***. on Reviewed in the United States on December 13, 2015* 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.👍🏼 ### ⭐⭐⭐⭐⭐ Better than Expected *by B***B on Reviewed in the United States on November 12, 2015* 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! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/24562652-koncen-x11-bluetooth-4-1-wireless-sports-headset-for-smartphone](https://www.desertcart.us/products/24562652-koncen-x11-bluetooth-4-1-wireless-sports-headset-for-smartphone) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
