If I had given these headphones a review two or three months ago, I definitely would have given them four or five stars--they've been my favorite headphones for years. Not necessarily because of the sound quality (quite passable but definitely not audiophile quality), but for the compact convenience of them: they fold up neatly and tightly and are easy to stow in a pocket or backpack. I've used these 'phones for years and they have always lasted many, many months until the wiring pulled out from the plug, usually through my own rough use. (A couple pairs on which I had the foresight to apply some precautionary electrical tape around the wire near the plug lasted for more than a year).
I haven't been able to find these headphones in retail stores for almost a year, so I was pleased when I noticed Amazon carried them. Several months ago I ordered a set and put it away for when I'd eventually wear out my old set. A couple weeks ago I at last switched to the new set, and two days after starting to use them, the headphones snapped in two at one of the folding joints--a problem I have never had with over a dozen pairs of these headphones before. Well, maybe that was user-error. I ordered two more sets and started using the first last week. It snapped in two the day before yesterday. The second pair snapped in two today. That can't be user error, that's faulty construction. I'm beginning to see why the bricks-and-mortar stores don't carry them anymore: I don't know what Sony has done in the process of the manufacture of these headphones, but they've changed them from my fave headphones to cheap breakable garbage. I won't be buying them again.
