It looks like it's a bit different. The EarPod teardown has a pretty nice comparison of the generations of earbuds from Apple in step 11. They look like they mostly have open-back designs while the new AirPods have a black plastic (and mesh?) that covers the back of the driver. Apple EarPods Teardown

I would be interested in seeing these compared to the new PowerBeats 3 since that headphone model also uses a membrane-style speaker in the midsection bulge of the stem.
