                  Wonderful headphones

                  I finally got my order. Delivery is very fast. The goods are satisfied. The seller is well done, respect!!! My friend bought one, I think the sound quality is very good, the price is still very cheap, I decisively followed him to buy one. This is a hanging ear type, fitness running is very suitable! !

                  Not bad.

                  For the price, they are a great pair of headphones. They sound good and the bass is decent. I loved the case, it’s well made. The reason why I’m giving them 5 stars it’s because they are extremely comfortable. I have small ears so I need comfy earbuds. This pair fits perfectly and when I’m working out I don’t have to worry about if I’m going to lose them! I love the ear clip it gives me a feeling of security.

                  Earbuds just OK

                  Cool headphones, good sound in general, good bass. In the ear sit well, but with unaccustomed slightly rubbing. If you smile widely to the ears, then fall out: dEach earpiece is defined as a separate device if you use one at a time.

                  best costumer service ever!

                  As soon as I received it, I immediately put it to the test under following situations:

                  - Yoga, where my head was upside down and sideways a lot, with lots of arm movement and up-and-down poses
                  - Jogging, where there was a lot of bouncing and noise from the treadmill
                  - HIIT, where there was a variety of upper body and lower body movement
                  - Hour-long public transit commute with my eye glasses on

                  Here’s what I learned:

                  Overall, it worked great and stayed on without any adjustments. Though the cord flopped around a little bit, I didn’t find it uncomfortable. During my run, I did notice that I could hear the vibration/noise of the cord rubbing up against something. It eventually became white noise, though.

                  I probably need to use a smaller earbud because after about 45 minutes, it started to bug my ear. The hook that goes over the ear was pretty comfortable, even with my glasses.

                  Great.

                  I've had these about a month. So far I am pleased. They meet my needs for a day on a single charge for off and on listening during my commute and during work breaks. The sound quality is good, and the range is adequate to my needs. Bluetooth connectivity has not been an issue. They work as intended.
