Selling TWO pairs of these fantastic headphones. I got them during internships and wore them very rarely and never during exercise. They are like new.

The HD 280 PRO is a pair of closed, dynamic stereo headphones that deliver accurate, linear sound reproduction with ambient noise attenuation. Optimum impedance ensures universal compatibility, from home listening to studio monitoring. The space-saving design features collapsible, rotating ear cups that are very comfortable to wear, even if used for long periods of time.

Amazon (slightly different design but technically identical): https://www.amazon.com/dp/B00IT0IHOY
They are $99.95 + tax new. I'm selling them for $80. $150 for both. Can meet up on campus any day.
