I recently purchased a pair JH16 from the forum and sent them to Unique Melody to have them reshelled. UM had the drivers measured and it appears to have a 6 db difference between the left and right midrange drivers. I was wondering if this level of imbalance is common in the JH16's since I've...

Not sure if anyone posted a heads up but I found 2 vintage pioneers for sale on eBay: the SE-700 and SE-500. Both piezoelectric headphones. Considerably rare. Would pick these up myself but they're pretty pricey. Could be worthwhile for collectors.    I have no monetary interest in the...
