After reading reviews, I was a bit skeptical but decided to get 5. I happened to uses studs to anchor this but the included anchors are really no joke. I love these shoes not only do they help with my rheumatoid arthritis but they are so stylish. I love these shoes and they love me! First of all I bought a TORRAS Slim Fit Hard Plastic Phone Cover Case. The build quality for this price is unbelievably good. However, after walking around in n them for 5 mins, my toes begin to hurt as well as the base of my feet. 5 so I ordered a size 7 and they were a little bit loose in the toe box area. - Some weird quirks Ive discovered: - Battery life, with Transparent Hearing on, is around 5 hours for me (same as ANC) - Surprising amount of wind noise when jogging/running with Transparent Hearing on - Cannot toggle Sidetone during a phone call (will effectively mute you) - Still have to turn the volume up more than preferred to get to a subjectively "enjoyable" level of soundORIGINAL REVIEW:Over the course of the past year, Ive tried out just about every true wireless earbud on the market I do have slimmer shaped feet- so if you have a wider foot OR your 2nd toe is much longer than your big toe (you know who you are :) this may not be for you.
