Etymotic Research Er4XR Extended Response Precision Matched In-Ear Earphones (Detachable Balanced Armature Drivers, Noise Isolating, High Fidelity, World Leader Response Accuracy), Black, Standard

I purchased it when it was a 450dhs sale. I mean this earphone is well-known for its superb sound quality. Although it is old, it still outperforms other IEMs in the market. Highly recommended.

The Etymotic ER4XR are my first dive into the world of high-end IEMs and I consider myself to be very lucky as I feel that I have reached the endgame. I've dabbled into midrange IEMs as I've always preferred these over other forms of headphones. Another testament of these headphones is the packaging and the amount of accessories that come with it.The fit of these takes some getting used to but once you do, they become extremely comfortable to the point that you forget you have them on. The audio quality is incredible and the imaging is some of the best I have ever heard. The XR has more bass than the regular ER4s however these IEMs are DEFINITELY NOT FOR bassheads. The bass however is very clean and fast and it never muddles the sound.Also, one thing to keep in mind is that once these bad boys are placed correctly in your ears; the isolation is just mind blowing. This is a completely different ballpark to ANC. It basically creates a vacuum chamber in your ears where even playing music at 30% level will cut out almost everything. I wore these on the plane and at 40% volume from a DAC-powered phone, I could NOT hear the plane at all.Just be wary that the fit is not for everyone, these IEMs will physically violate your ears for the first 10 days of you wearing them. Start slow and slowly your ears will adapt to the feeling.

As a professional sound engineer, these are the only in ears that I can mix confidently with, knowing that my mix will playback nicely on anything. I started it with the SR 4 then moved to the XR 4. The SR are perfectly fine but the XR has a slight boost in the bass that resembles a studio subwoofer. These headphones are super flat and truthful, they tell it as it is, no gimmicks here. I initially ordered the $1000 sure Se 846 gen 2 monitors, to keep it short, don’t follow the hype and the YouTube reviews……these are the only in ear monitors that come close to my trusty Genelec monitors, cold, harsh, flat and truthful, no make up here, no eq, no boss or gimmicks, no multi drivers that are full of phase issues and frequency dips, no disillusioned Audiophiles who imagine frequencies. This is the best in the business period. If you want the best hyped sound then get yourself a Beats headphones and enjoy your workout!

Wonderful quality! Best sounding IEM ever listen to!
