        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?

        Just received these and was amazed with sound quality. The ease of use is great also. Setup a breeze. Only complaint is the user manual. Better get a good magnifying glass.

        Nice buds... but

        Headphones came quickly. Sound quality, the microphone is good, comfortable. Very satisfied. The only negative is the problem with connecting two headphones, not convenient.
