Id highly recommend. 0 and I ordered a 5. fit perfectly Confortable, lovely, I have taken a Large size and I?m 9. They fit true to size which was my only concern because buying footwear online can prove to be tricky. Pros: Easy to install, about as comfortable as the originalCons: Perhaps a little more muffled than the original ear cushions, but they might break inNotes: At first, they make a lot of crunching/shuffling noise when you put the headset on, but as they sit for a little bit and take shape the noise goes away. This is the best waist trainer! these dont even have the bottle cap opener on the sole. The case is really great, but not right for the JBL E50BT as they said. Nonetheless, pretty good for the $$
