            First shipping

            Great sound! Nice bass, mid and soprans. Very good seller, good contact, fast delivery! Just one week! 5 stars!

            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.

            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.

            Hi Joseph,

            Thank you for taking time to leave us the product review so that we could be better informed and hence improves our product quality.

If it turns out to our problem, we'll be more than glad to offer exchange or refund for you.

            Please don't hesitate to contact us or send us by email: uiisiiservice@gmail.com with your order # and the problem you come across. We will reply you within 24 hours.

            Thank you!

            I ran them through the washing machine and they still work

            Okay so I don't recommend that you try this, I accidentally left them in the pocket of my jeans when I did laundry, and amazingly they're still working great even after a trip through the washing machine! The other things I like about these headphones are:
            - they fit small ears really well. The design fits my ears well and doesn't fall out very often. Much better than the style of workout headphones with a piece that goes over the ear like a pair of glasses.

            Not bad

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