El único detalle más débil son los plásticos q lleva para montar las divisiones. I found the MDR-EX15 on Amazon but the sound quality on these is now horrible. I tried 2 different pair of the Zvolv, with the same result, they were too small. not as good a quality as you would expect from crocs started to fall apart quick Likerly to purchase a half dozen just to keep around. It really is very simple as long as you fully understand the process and prep everything before you start. I recommend them The tray attachs using a compression fitting. Unfortunately, the headphone jack is only audio out so he had to rearrange the cords and plug the headphone jack part into the tower and the USB into the base. But these, are so comfortable I forget it actually has this part.
