Found these in my Audio Room so I thought I would give 'em a try. Plugged 'em into my portable bluetooth headphone amp and initially they played louder than my Sony MDR V600's. Adjusted the volume down I like 'em they sound good, don't detect distortion, clear, with good bass & treble. Definitely will be using often while at my desk.
These date back to 1990 where I probably used 'em with a Walkman.
