Etymotic Research ER2-XR Extended Response - In Ear Noise Isolating IEM Earphones with Detachable Cable

Product Information

Because the insertion is much more shallow with these other tips, I find the sound stage to be a bit wider, and the music doesn’t sound like it’s in the middle of your head as much. The main correction is actually on the 4-5kHz treble peak which is already present in ER4XR but absent on ER2XR and ER2SE.

Whatever your preferences, you can’t go wrong with any of these from the list, as all these entry level IEMs are at least good, if not superb.The bass boost alone makes me prefer the 2 over the 4, but there was also an unexpected difference in soundstage.

ER2SE is a great choice for audio creators and musicians on a budget, who require a precise and neutral sound reproduction. I probably won’t be writing Cliffnotes for every IEM, but you can expect them for the ones that stand out, either positively or negatively. From ER4XR to ER2SE – To get similar output i had to push the ER2SE’s volume one notch higher in my HTC10. It is a deep insertion micro dynamic driver design with almost ruler flat impedance across the audio band.Not sure if you have gotten it, but you can get an adapter, or make one using microtape and taping around the nozzle, to take on different ear-tips. Do they protrude too far from the ear to be comfortable to wear underneath noise cancelling headphones? 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.
