          Customer Reviews

          My go-to earbuds

          These are very, very comfortable to me (they fit a lot like their pricier options) and they are lightweight, have a good all-around sound profile and have a great connection distance and consistently strong. I also wish they had some sort of magnet on the backs of the earbuds to have them connect when not in use because these have a proclivity to turn halfway around my neck and almost fall off. These are not the most expensive wireless earbuds to a lot of audiophiles but to most people they aren’t cheap, either. With that being as it may, these exceed a lot of benchmarks that I look for in a set of wireless earbuds and are lacking in others. Here’s what I think:

          Good all around sound
          Adequate bass and highs
          Super comfortable
          Not bad noise isolation (passive)
          Great controls (power/ volume up/down, etc)
          Outstanding Bluetooth range/connection
          Mic quality is good


          No way to wear without them flopping around

          No active noise cancellation (but no extra cost, either)

          Overall, I like these a lot and use them for audio books, music and such when I’m working because I’d rather lose or damage these than a set that is 3 times as costly. These work for me for a sort of universal headset where they don’t do a couple things exceptionally well but rather do a lot of things in a very good way

          Uiisii BN90J in ear headphones

          I will say that so far I am pretty satisfied with this product, my only complaint was I got mixed up and thought they came with a nice little carrying case. I haven't used them at the gym yet but hoping they keep up with my sweat with the water resistant technology. The sound is really quite amazing I must admit, just hoping they last me a long while. Thank you thus far as I am impressed.

          Uiisii did it again!

          Loved the sound quality of these headphones, didn't love the fact that they are $10 cheaper 3 days after I bought them

          Dear Alex,

          Thank you so much for your support. We are so happy you like our headphones. We work hard to meet expectations like yours, and we’re happy to hear we hit the mark for you. Please don't hesitate to let us know if you have any other comments. We'd love to hear from you!
