I'm interested in the ER2XR and I have a few questions I was wondering if anyone could answer:
- How does the level of isolation compare to the Mee Pinnacle PX, with or without triple flange tips?
- Do they protrude too far from the ear to be comfortable to wear underneath noise cancelling headphones?
- How low is the bass extension? If you use an app like Frequency Sound Generator on Android, what is the lowest you can hear below 30hz?
- How is the sense of impact from the sub bass?
- Anyone tried putting a foam tip or a hole punched foam earplug on the body of the unit behind the eartip? If it works this could be a good way to further increase isolation, but I'm not sure if it would be comfortable with the angle of insertion.
