These are the greatest headphones in the world. I bet I wear them 12+ hours everyday. I can listen to music and have a conversation. I can go exercise and hear my surroundings. The better life is great, and they weigh almost nothing. They also have a 2 year warranty, which means I've purchased one pair in almost 4 years after a driver disconnected in the ear piece. I would have gladly paid to replace them though.
