Both headphones in beautiful condition. Original owner, non-smoker. Momentum has a new genuine Sennheiser remote cable ($$) and a after market straight regular cable. New genuine regular cables are still available for only $12. Great condition and fantastic sound. HD-598se are in beautiful condition, too. No crud on ear pads ( I’m a very clean guy! ) They are like new with both Sennheiser cables, one short and one long (3m). No retail boxes, just the Sennheiser case for the Momentums. I moved (retired)to a very noisy area in LA and will get noise canceling headphones.
