        Great headphones

        The sound quality is chic and the headset itself too. Before altai 23 days, the courier brought to the house. All the reviews are true, people take and never regret. On the neck and in the ears sit perfectly, you can do everything in your head they will not fall. Another headset Uiisii model is weaker and older at me serves as faith and truth for 4 years and even the battery did not die. Great brand.

        Not bad

        Impeccable. Good quality in relation to the price. They listen very well and look good. Recommended.

        Functional, sound quality is OK

        I can hear static noise in the background when no music is playing and the sound quality is definitely not the best (you get what you pay for though probably). The noise cancellation is pretty decent, and the magnetic buds are excellent. I wish that the earbuds were a little smaller though, because it hurts my ears if I leave them in for too long because they are too large.

        Very good product at a great price point, bought two

        I actually own two of these because I misplaced my first pair. Two weeks later I found them outsider in my rock where they had been getting rained on and hit by sprinklers every day, a little dirty but still work like new. These are good quality at a price point you don't have to worry too much if you lose or break them. I am an endurance athlete and use them during running and strength training.
