I am an active person with small ears. Wearing earbuds inside my ears is uncomfortable and doesn't allow me to hear ambient noise. I bought these as an alternative to my Shokz which are fantastic - except for the band around the lower part of my neck. These have a great fit. You hardly notice them. The sound is INCREDIBLE! I really like the pop of color (I chose the ruby ones). I read on another review that they seem to get tighter when you sweat. I did notice that as well. In a way, it made me feel more secure. I would hate for one of these to get lost on a run! Overall, I am happy with the purchase.
Had them a few weeks. I like how they stretch to stay in place and are comfortable. Don not slid from ear like some other type. The open air allows for conversation when necessary but also limits sound level for the ear since they’re not in the ear canal. Battery life seems good , so far.
