    Etymotic Research ER4SR reviews

    ER4SR In-Ear Studio Reference Earphones is rated 5.0 out of 5 by 4.
    Rated 5 out of 5 by from Unique, spectacularly transparent, not for bass heads I am not a big fan of IEMs, I prefer over the ears headphones but ER4SR are special. With proper sealing they sound spectacular, but the seal is absolutely critical. That means you have to be OK with triple flange ear tips going really deep into your ear. It does not bother me, I know people who do not like it, but I think this is the only way to listen to the ER4SR full potential. They need good amplification as well. I do not treat them as IEMs for mobile device, for that I have SE535. But if you really want to hear your music get those. Superb noise isolation, superb sound, if I had to live with one set of IEMs that would be ER4SR

    Rated 5 out of 5 by from Sugar-free sound The transparency you get with this earphones is like nothing I've experienced before. I had the Audeze EL-8 CB + AudioQuest Drangofly Red 2.0 (connected to a laptop or to an iPhone 7) and I ended up selling it because, to my untrained ears, the sound was good but not great. I read this earphones are famous for their flat response. No flavors in here: at Etymotic they are obsessed with delivering to your ears what was originally recorded at the studio. Of course, I have no way to validate such claim. What I can validate is that I haven't experienced a sound so detailed and rich before. Every instrument in its place, not fighting to fill up the air. Now I realized how conditioned by the bass was my listening experience before. This earphones is like starting a sugar-free diet. And the vocals, wow, it's like the singer is sitting next to you. Listen to The Light (masters edition) by Regina Spektor on Tidal and you'll know what I'm talking about. I've paired this with the Oppo HA-2 SE.

    Rated 5 out of 5 by from Accurate sound reproduction for sound studio work What do you want to do with these headphones? If you want to listen to the music while commuting or traveling DO NOT buy these. Buy its twin ER4XR where X stands for Enhanced and Extended Bass. I bought these because for my home video sound work I need a very accurate sound reproduction and I get this using these headphones.

    Rated 5 out of 5 by from incredible audiophile sound I LOVE these headphones!� I am using them with custom ear molds (worth every penny).� They sound great just plugged into an iPhone, but if you want to get your full $ worth, I suggest lossless source files (Tidal or better) and a great DAC/AMP.� I invested in a Chord Mojo to pair with these and could not be happier.� I fly a lot for business, and my life just got a lot better...
