I've had Sennheiser headphones before, but after working out with the wraparound style, I have gotten used to that type. I stumbled upon this new model and saw that the price was pretty darn reasonable so I thought I would give them a try. The sound very full with great bass response fo0r headphones of this size. The sensitivity is such that they can overcome any background noice which is good too. Very nice Sennheiser.
