IN TERMS OF THE AUDIO THESE HEAD PHONES SEEM FINE, ALTHO I PRIMARILY USE THEM FOR BOOKS SO THE QUALITY OF TONE MATTERS LESS THAN IF I WAS USING THEM FOR CLASSSICAL MUSIC. THEY ARE A TRIFLE BULKY EVEN WHEN FOLDED.BUT AFTER ONLY A FEW WEEKS OF USE, I FOUND A CRACK IN THE COVERING THAT EXPOSED A WIRE. I HAVE COVERED IT WITH ELECTRICAL TAPE AND THEY ARE WORKING FINE RIGHT NOW, BUT WHO KNOWS FOR HOW LONG. MY HYPOTHESIS IS THAT THESE PHONES WERE MADE SOME TIME AGO AND THE RUBBER/PLASTIC WIRE COVERING CRACKED WITH AGE...BUT WHAT DO I KNOW???
