Used for a bar. airpods) when much better, higher performance earphones (like these ones) are available at a fraction of the price. These are the BEST shoes for summer. Fantastic stuff to have around, for sure! I ordered the medium and they were very generous. After that disappointment i went back and researched again and settled on these which again are number one or two consistently on everyones top ten list. They matched my dress perfectly, but my feet were so swollen and sore on my wedding day, I couldnt wait to take them off. This took a bit to learn the right placement for changing. I returned this one and bought the Jabra Engage 75 Mono Wireless Professional UC Headset, this "Mono Wireless" one has a bigger "ear piece" that while a little too large, and sort of dorky looking, has an actual "foam" earpiece and is NIGHT AND DAY more comfortable than the "Convertible" one. When listening to music, I noticed that this headphone has a hard-punchy bass.
