    Best ANC earphones especially if you’re a Samsung user. Don’t like the fit for workouts

    Pros- clear audio, great bass and easy multi connect if you have Samsung ecosystem. You can have a conversation with people wearing these-ambient mode is unlike any other earbuds which makes you feel like you need to take them out to hear clearly. Best for day to day use, be it listening to songs or podcasts while travelling or making calls with a sense of what’s happening in your environment and hearing your own voice. Cons- don’t think they have the best fit for workouts. Used to Jabra (like elite 8 active) which feel secure and rugged for intense sweaty workout.

    Perfect earbuds

    Purchased for my wife's birthday. She loves them, fit really well and great noise cancelling. Got them for a good price too.

    Truly Amazing

    My 4th iteration of Samsung buds. Everyone has been blown away by these. The sound is better than my $6000 Bose surround system. Easy setup and play. If you are using Samsung or Android this is a no-brainer.
