Alright, here's everything I like about this product:
1. Great price
2. Sound is clear, base hits, and notes are distinguished.
3. Soft padding on the speakers so it's not too uncomfortable when tight on your ears.
4. Battery life is LONG! 60 hours without ANC! (not sure if it's exactly 40 hours with ANC but it's still long)
5. Very quick charging
6. Comes with a travel case and AUX cord to make the headphones wired if battery runs out. (however, wired does disable features)
7. Noise cancellation is brilliant
8. They just look cool
9. The speakers turn in many angles to properly cover your ears.
10. Overall build quality is very good
Now, here's everything that i dislike about this product:
1. Too big to properly fold
2. Holding button for a long time to power on and off is annoying.
3. Audio deafens for a bit each time you switch modes.
Despite the minor dislikes, this product gets 5 stars from me.
Do I recommend it? Absolutely.
Will you regret buying? I very much highly doubt it.
