Title: Refurbished -- but still defective
Review: I bought a refurbished pair for $ from an Amazon partner, "...". They came in some generic packaging with photocopied instructions and a 30 day non-manufacturer warrantee. Evidently there's now a mini-industry of businesses that handle returns and refurbishes them.At home they seemed to work. With noise reduction on they had a soft background hiss, and if I moved around in some noise settings they produced an annoying buzz. On an airplane, however, the right earphone produced an earsplitting whine. The headphones are defective, the noise canceling mechanism is malfunctioning.I have a nasty suspicion that the headphones were rather minimally "refurbished", and that this defect was the reason they were returned in the first place. It wouldn't show up in simple testing without an airplane volume noise source nearby.Don't buy these refurbished headphones unless you have money to waste....
