How well do they stay in when you're active? I need ones that won't fall out when jostled. That's one of the reasons I was considering the PowerBeats 3. They have the little part that wraps around your ear.

I've always used Klipsch s4s. I love their sound but damn every time that cord bounces off you it's a echo of sound lol

Then they might not be the best choise, I would take a look on Sennheiser sport models if you need something that sounds good and stays on place.

Gonna have to pass on that lol

They have quite many different models tho, some of them indeed doesnt look so good but some look quite promising imo.

i just bought these actually

waiting for them to arrive

I'm still trying to decide. I have this coming in the mail today for my PC:

hahaha my sweet summer child

They're 598s with a mic. Seems good.

Get the SE215. They're great in ears. I bought mine with the intention of buying better ones. Since they're popular, you'll find many reviews and comments comparing or referencing the SE215. That should make your future purchases easier as you'll have a reference.
