Sound is great on these. The sub is more of a shaker but cool, and adds a lot of bass. Make sure you bring an extra aa battery with you because you nvr know when it's going to die. The phones still work but no bass when the battery is dead. Don't like the fact that they have wires coming from both sides, and the battery should have been integrated into the headset in my opinion, makes them a little awkward. Overall I am very happy at this price point for them.
