Bought these to replace the woefully-poor-fitting ones stock with an Aliph Jawbone Era. But I say go with the size chart or order two and return the one that doesnt fit. I got rid of the boxes and have a more organized closet. installed new Volex power cord with additional ferrite beads. Overall, it?s a great bench. They don?t fit well enough to tell if they are even comfortable or not. Looks great and organized spices perfectly. Id order a size down. Had to downshift to stay at max resistance. Im a huge Sennheiser fanboy.
