        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:
        Pros:

        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

        Cons:

        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

        More Uiisii value

        Liked it a lot, sounds good for Bluetooth, not wonderful. Bass is good but I like a good dollop compared to a lot of people. The treble is where I think it falls short, it sounds like it's in the background for lack of a better description. It's clear but is not pronounced. The buds stay in pretty well but have the familiar thud that many buds have when you jog and take a step. The price is right and are above average for working out or bike riding, etc.
