I listen their sound and it was cool. Unfortunately I loss. I buy a dell laptop and they give me dell byte Bluetooth headphone. First I saw and think whats that because I always thinking about brands and this brand I never listen, but when I listen their sound it’s amazing and I love that. So I suggest all you guys to buy this headphone. It’s design and look is amazing. When you listen then you know its performance. It is value for money. I am overall satisfies this headphone.
