Good headphones with solid BT range and incredible battery life(took me 2 weeks of on and off use to get the case to turn red) my main issue is with how there's nowhere to secure the ear strap on the case so it just kind of fits around it until you lose it. If you want perfect audio quality look elsewhere as the way these sit loses a bit of the sound, but if you want these for a jobsite or the gym they're a pretty solid choice as you can hear the world around you still.
These earbuds are excellent. the noise-reduction is excellent and puts what your listening to on top of background noise so you can stay focused on that while still being able to hear the background, The sound quality is excellent especially if you EQ it raising the highs and the lows while attenuating the muddy mid-range.
