These are by far the most convenient, well built, comfortable and longest lasting headphones that I have owned. I have been wearing them for years and love them.
These are great headphones for running and biking. The sound is strong and it's good to also be able to hear other things in my surroundings. Easy to adjust the volume and turn on/off. I first ordered the regular size (not the mini) and it was too large for my head; the minis fit me much better.
I have a set of the regular size and really like them, so I bought the mini for my wife. I do wish I had chosen the mini for me as well, as the regular has too much band hanging out the back for me. I did the measurements, but the mini still fits better.
I bought the OpenRun’s for running. They sound really good, better than I expected. Sound is crisp. I listen to electric music, and while the bass is a little light, I am happy with the overall performance. I don’t like earbuds, so was looking for an alternative. The fit is very comfortable and is easy to adjust volume while running. Can’t really tell I am wearing them. I wear a mens medium/large hat, but opted for the blue mini as I wanted a tighter fit. Fits great. Bought these on sale and definitely recommend.
