These headphones give you a good taste of what the much more expensive HD660S2 can do for a very reasonable price in comparison. These aren’t terribly hard to drive and will sound great on any type of music that you choose to play on them. Very smart looking in the Ivory finish. These are a best seller for us at promo pricing.
