How many drivers per ear piece are there?

From the manufacturer's website. "Using a single Balanced Armature (BA) driver allows for extremely accurate IEM without the added complexity of crossovers, and helps keep the aluminum body small and slim." So that means 1/ear to me.

I have been using Etymotic mk5 phones for a long time... would these have a similar level of comfort, or perhaps be more comfortable?

The ER3SE earphones are as comfortable as your choice of earplugs. You have a lot of options including those from other vendors. I have seen the three-lobe models, two-lobe models, foam, and made-to-order custom-fit earplugs. Personally, I found the two-lobe earplugs to be comfortable and Westone makes a very comfortable custom-fit earplug that will last for several years. If price is not a problem, I highly recommend the Westone made-to-order earplugs for the ER3SE. They provide the most comfort and the best noise isolation.

Can the main detachable peice be replaced (not the detachable foam part but the main driver)? I'm getting low volume on one side.

With low sound on one side, the first thing to do would be to replace the filter. It's probably clocked with earwax. They're replaceable and that's what they're there for. Otherwise, when I sent in a pair of earphones, they replaced the earpiece/driver on one side.

Are these good for listening to music through my phone? Or are these just made for studios?

I use them with my phone all the time. They are really good at blocking the outside noise. I love them when I'm flying.
