High Sensitivity, Impressive Isolation

From Etymotic’s newest lineup of acclaimed IEMs, the ER3SE and ER3XR use high-performance, precision-matched balanced armature drivers. These high-sensitivity IEMs are a great match for mobile sources like your smartphone or portable digital audio player. For those who prefer a stronger low-end response, the XR version delivers a modest bass boost over the SE. Headfonia reviewer Lieven says, “If you know that custom IEMs most of the time offer a -26dB isolation, then you immediately know these Etymotic IEMs are very special. These ER3 and ER4 IEMs simply are the best isolating IEMs in my collection. Actually, they have the highest documented noise isolation of any earphones or headphones on the market today. Very impressive!”

Note: At checkout, choose the ER3SE or the ER3XR.

Ok I have to reply myself obviously as my ER3XR have arrived and I had some time with them in the meantime. They are definitely a big step up over the MK5 with more refinement to the sound, better treble and a nicer soundstage with better 3D sound. Many claim Etymotics to have a narrow sound stage which I personally cannot quite confirm. They do not exaggerate and make the stage broader like many other headphones. When I listen to my own binraual recordings the imaging is spot on, I can localize every aound source precisely while with many other headphones claimed to have a huge sound stage imaging is way off in this case. But back to the ER3XR compared to the MK5. I had harder time to really get the best fit than with the MK5. The MK5 tend to sound thin and mid-focused compared but there is a trick to make them closer in sound to the ER3XR. Use the large tri-flange tips, shorten the stem until the biggest flange and then cut the lowest flange away. This way the mid honkiness get away, bass improves as well as treble. So with the ER3XR with its stock smaller Triflanges compared to the MK5 bi-flange mod the tonality is quite similar but the ER3XR has more overall sparkle, something I was always missing from the MK5, there is also more air between instruments, it simply sounds more high-end. When I tried the bi-flange mod on the ER3XR they became boomy and muddy at the same time. I definitely prefer them with the smaller stock tips. I would still like to try out of the ER4XR would give me additional improvement. I saw measurements suggesting that it has even better treble extension. The ER4XR might be my next purchase in case there will be another drop. Unfortunately my ER3XR broke after 2 weeks of use. The right unit started to cut off and lose contact, swapping both sides didn't change anything, it must have been the driver unit itself or the connector on the driver part. I contacted Massdrop because of this and get my money back within some minutes. Respect for that kind of support! Now waiting to grab the ER4XR hopefully soon!
