Have handled my falling asleep with them in, being thrown around by my younger brother, and more without giving up on me. Which is a testament to their resilience and quality methinks. I was worried they wouldn't fit my ear size as well but they're doing fabulously.

Would be five stars but the ‘hook’ area to the earphones do come loose from my ears. I have relatively small ears AND I wear glasses so it always has been a struggle, but I did expect the shape of these to mitigate these, somewhat. However, these would definitely fit someone with dumbo's ears, its just a matter of readjusting once or twice during your walk/run. If you're stationary, like at a desk or laying on the couch, these are five stars, guaranteed.
