When working up a sweat, they don’t have any ventilation so your ears get all sweaty

They definitely fit me quite well even though my head is a bit large and I need to extend both earcups fully for them to fit my ears well.

Only negative is that I use them in the gym and they generally stay on my head/ears just fine, but when I change positions a lot for different exercises, sometimes they don't stay on quite as well.

ears sore after

Even just using them normally (not workout), my ears were getting so uncomfortably hot that I had to take them off every now and then

but I have sensitive ears.

Hold down he large button on the right ear to activate Siri, or im assuming whatever virtual assistant your phone offers

The headphones are not as durable as I would like them to be and being geared to those who workout
