          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
