          Customer Reviews

          Based on 21 reviews
          Great at 40$ but not mind blowing

          Since a lot of reviews go really in depth, I’ll keep it short and simple:

          Durable, small, light case
          Every earpiece and bud piece you need included
          Super easy to set up and use
          Bluetooth 5.0 is amazing
          At 40$ is an absolute steal

          Audio quality is very meh. Pretty balanced but the mids are hard to hear and the bass may not be as bumpy for hip hop or edm

          Uncomfortable for smaller ears. They barely fit in mine securely and after an hour or so, start hurting a bit. I’ve spent almost 2 hours trying to find which pair of buds and earpieces worked and it still isn’t a perfect fit. In particular, the left earbud doesn’t secure as well as the right one

          You really need to turn this up to at least 60% to actually hear your music properly

          Average battery life. Just okay and not amazing by any standards

          For 40$, I’m really satisfied with my purchase. I tend to use these during commutes and for short periods of times. Are there better option? Yes but can you really beat the price they are being advertised at?

          Dear Daniel,

          Thank you for your reasonable review.
