The IEM shells are made of anodized aluminum, CNC machined with extremely tight tolerances. Using a single Balanced Armature (BA) driver allows for extremely accurate IEM without the added complexity of crossovers, and helps keep the aluminum body small and slim. Included is a user-replaceable cable. Etymotic IEMs are world renowned for their class-leading passive isolation, providing 35-42 dB attenuation (depending on eartips used and the depth of insertion). For comparison, most custom IEMs provide approx. 25-28dB attenuation and foam ear plugs attenuate up to 32 dB.

That means no amplifier is required to drive the ER3 IEMs properly. The only difference between the 2 models is the tuning of the lower (bass) frequencies. The “Studio Edition” ER3SE is tuned to have a flat frequency response. The “eXtended Response” ER3XR is tuned to be high energy with emphasized bass, adding 1-2dB to the mid-bass and 3-4dB to the sub-bass. The rest of the frequencies are practically identical to the ER3SE. ER3SE is a great choice for audio creators and musicians on a budget, who require a precise and neutral sound reproduction. ER3SE is also the IEM of choice for prosumers who prefer to listen to their music exactly the way it was recorded. ER3XR is favored by those who enjoy the extra bass presence and body when listening to their music. The extra bass is done tastefully without turning the ER3XR to a bass heavy IEM.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency response graphs and Etymotic’s target:\u003c\/strong\u003e\u003cbr\u003eEtymotic’s target frequency response graph represents a “perceptibly flat” frequency response. Our goal is to have a flat frequency response curve when the music notes hit your eardrums. To achieve that, we need to account for the resonance inside the average ear canal, since IEMs bypass the outer ear structure. The result is the need for higher SPL in the 2-5k region (lower treble) for compensating said resonance. That is the reason for the “hump” in that region. The target curve that Etymotic is using for tuning our IEMs differs slightly from the Harmon preference curve.
