I thought these would be more comfortable. They are okay for day use, but for someone with insomnia like me, that uses sleep stories, the portion that goes into the ear was not very comfortable.
I bought these for new running earbuds but they are not good. The first problem was that they will not work together when paired. For example, the left bud will only play while the right in silent, and if you try to connect the right bud it will stop the left one from working. The other thing, they are very uncomfortable to wear. I tried all the ear piece sizes but none were comfortable. The last thing which isn't a big deal but it comes as an inconvenience for travel use. The travel case is HUGE (cue in the “that's what she said” comments), like I can't fit it in my coat pocket. So if you were to go out running you'll have to leave the case behind.
