Designed for Musicians who want to hear naturally but need protection when hearing is at risk. Using active technology that constantly evaluates incoming sound the Music Pro Elite gives you two modes of operation. The Low mode gives you transparent pass-through audio under 90db. When the 90db threshold is passed it gives you 15db of attenuation for material above that level with a super-fast attack and release with the effect of only attenuating that sound. If it’s a quick snare hit, you will hear the natural sound of everything else except that the snare, which will be attenuated as briefly as it happens and then levels go back to normal. If it’s a steady guitar amplifier sound over 90db the sound will be attenuated as long as it is present. In High mode you get 6db of natural level gain under 90db with 9db of attenuation over 90db. The battery life is unprecedented in that out of a single charge on the ear buds you get 16-20 hours of use and an extra15+ charges out of the case itself.

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. The included high-quality user-replaceable cable is reinforced and twisted, to improve longevity and durability.\u003c\/p\u003e\n\u003cp\u003eEtymotic IEMs are world renowned for their class-leading passive isolation, providing 35-42 dB attenuation (depending on ear tips 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. The ER4XR is a must-have for audiophiles and consumers, looking for very accurate in-ear monitors with a taste of added bass, for a more \"fun\" sound signature.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich ER4 is right for you?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth ER4 models, the ER4SR and ER4XR, use the same Balanced Armature (BA) drivers. The only difference is the tuning of the lower (bass) frequencies. The ER4SR, being the \"reference\" model, is tuned to be as precise and flat as possible. The ER4XR, being the \"fun\" model, is tuned with added bass. As you can see from the frequency response graphs below, ER4XR adds 1-2dB to the mid-bass frequencies (below 200Hz) and 3-4dB to the lower-bass and sub-bass (below 100Hz). The rest of the frequencies are practically identical.\u003c\/p\u003e\n\u003cp\u003eER4SR is ideal for sound engineers and mixing technicians who must have a precise and accurate sound reproduction across all frequencies. ER4SR is the IEM of choice for audiophiles and consumers who like to listen to their music exactly the way it was recorded.\u003c\/p\u003e\n\u003cp\u003eER4XR with its tastefully added bass is favored by audiophiles and consumers who prefer a little extra bass presence when enjoying their music. This model is not bass heavy by any means.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Frequency response graphs and Etymotic's target: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\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.\u003c\/p\u003e\n\u003cp\u003eThe target curve that Etymotic is using for tuning our IEMs differs slightly from the Harmon preference curve. It was developed in-house more than 20 years ago, leveraging on our human hearing expertise and acoustics research.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAccurate Earphone Reproduction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhen tuning in-ear monitors to accurately reproduce a recording of a live performance, our goal is for the sound hitting the eardrums to be identical to that at the original performance.
