Im giving these 5 stars because one is getting so much shoe for the money; I would have gladly paid more if the shoes were more . So to end this, Im sure Ill have these for at least another 10 These are the best "non OEM" replacements Ive used to date. Keep in mind that my go-to headphones are Grado 325s, so head-shaking bass is not my priority (though I definitely appreciate it if the genre calls for it). Wore once on treadmill for just two miles connected to treadmill tv and no problem. I wear a sz 8 and had to purchase the sz 8-9. Very convenient and I dont have to split my time between music and charging! Jay called back literally 10 seconds later. Instructions were clear. Very good sound with enough Bass to keep me happy (and I dont need too much Bass)Nose cancellation is OK, (about what I expected)Comfortable.
