Etymotic Research ER2XR Extended Response High Performance In-Ear Earphones

The new ER2SE delivers clear, accurate sound using high performance dynamic drivers. The ER2SE offers Etymotic’s renowned isolation featuring a variety of eartips to provide 35dB+ of noise reduction so you will hear all the detail buried in the mix without raising the volume to compensate for ambient noise. The flat frequency response of the ER2SE will appeal to sound professionals and audiophiles alike. (Detachable Dynamic Drivers, Noise Isolating, High Accuracy, Studio Grade Accuracy)

Much is made about the fact you need to invert the ER2's into your ear canals. This is much todo about nothing! Like any IEM you need to adjust to warring the ER2's but I found myself acclimated after a few songs. I purchased both the SE and the XR and I will say what the manufacturer describes here in the product listing is spot on as to the sound profile of each earphone. I think I favor the SE for most of my listening but there are times you just want that extra in the bass and the XR delivers that without compromising the mids and treble.  I own a number on IEM's and Headphones at many price points and the ER2's are the best sound value on the market.

The sound reproduction is amazing

Lucid Hearing

At some point the foam tips were no longer available.  I have fancy hearing aids and The Beans.  One thing about The Beans, I don't have to worry about recharging.  The batteries have not become too little for me to manipulate....

Tried getting them years ago; glad they are back!

The foam tips are very comfortable. My only issue is their lack of availability. 
I have been using bean for over ten years. Please keep making them.

They are well built,  I shoot 2 times per week and have had first set for at least 6 months.
Perfect fit and retention.

These are perfect

Impressive for the price, great detail and sound. Only concern is if my hands come into contact with the headphones while listening to some tunes, it becomes somewhat staticky. I will be working on an exchange with Etymotic as they have fantastic customer service.

Crystal clear and defined

They seem high quality but they are too small for my ear canals so they don't block out a lot of noise and sound very tinny. I could not find the ones that I have used before on the website.

Too small for me (adult 170lbs male)

I really wish Etymotic would post the actual dimensions of more than just their double flange tips. I had to order these to find out they are still too big for my tiny ear canals (the diameter is about 10mm for anyone with similar questions). The foam is also on the rough side, so even cut down to fit in the larger, outer part of my ear canal they weren't super comfortable. If Etymotic had used softer (or at least smoother) foam, these tips would likely have worked for me once cut down to about half their original length (which would have also given me twice as many tips to use).

Ordered for use with Akoustyx R-120. Tips are decent, but still too big and kind of rough.
