1More Triple Driver vs Etymotic ER4SR

I want something that will have a good bass profile and overall sound quality, no muddy bass or piercing highs, and can hold a stable connection to iPhones/Apple products.

Went with the studio reference version because I don't care for too much bass, and I can safely say there is a good amount here. The bass is present, clean, well-defined, and it's not so much that the sound is muddy. The isolation is fantastic of course, provided you can find the right fit for your ears. I use the standard tri-flange tips myself

Orchestral tracks, like the opening scene in John Adams' The Gospel According to the Other Mary, sound phenomenal. You get the richness of the lower register instrumentation and the bright treble edge of the higher register strings, brass, and vocals perfectly complementing each other. The balance here is nearly perfect, with the bass response playing a supporting role without shrinking into the distance—you get a wonderful sense of the space the recording was made in, and ideal clarity throughout the entire frequency range.

It's one of those IEMs that 'wow' that sounds like actual clean water. Something difficult to find in most price ranges today < $1000. Of course, I'm biased as a happy Etymotic ER4SR user. The journey to ER4SR included so many IEM testing including models like Shure SE846 that I'm a full Etymotic believer

and that is a problem. A $100 pair of IEM's isnt disposable. You should be able to fix them. No excuse for not being able to

5mm connection, but ship with a sturdy 0.25-inch headphone jack adapter for use with studio and stereo gear.

its just a SHAME! (Look at the pictures) COMFORT: - They are not comfortable at all, you have to find the right Tip for you... the plastic Tip because probably the foam one is already broken

This is for discerning listeners. It's sound as real as it was recorded. If you like the thump and the hiss, these are not for you.
