ER4XR

接続部が独特なのでリケーブルは専用品が必要です

値段は以前の定価くらいでしたが、Made in USAのもの(パッケージが赤基調)が欲しくてあえて中古で買いました。 ヘッドホンはHifiman ANANDAで以下の構成でレコードのDSD5.6MHz録音を聴いています。 環境設定をする時に夜使う時に動作確認用に購入しました。 Rock5b→FX-AUDIO-PGN2→iFi hip dac2→TOPPING A30 Pro イヤホンはIE800しか持っておらず、感度とインピーダンスがANANDAに近くなる本製品を選びました。 TOPPING A30 ProはデジタルボリュームなのでMAX0dBで使うことができるのがポイントです。 想定通りANANDAと同じボリューム設定で聴けています。 最初、高音側があまり出ていないので失敗したかなと思いましたが、フィルターを交換したら綺麗な高音が出ました!

良いです。商品そのものが長く高評価な理由と思いました。

この3年ほどで、数え切れないほどのイヤホン、ヘッドホンを購入しました。 予算は上限10万円ですが。 新しいものが届く度に、一喜一憂し、前のものと聴き比べ 喜んだり落ち込んだり。 「他にもっといいのがあるはず」という期待感のもと 散財を繰り返しました。 もし仮に、イヤホンの音に「正解」があるのだとすれば、 このER4XRのような気がします。 私はエージング信奉者（笑）ですが、これはエージング前から いい音を出してきました。同時に聴いていたAnandaの音が こもって聞こえるくらいに、いいサウンド。 世の中には、これより高音質（あくまで主観と思いますが）高価格のものは 沢山ありますが、一つの指標、到達点としてER4XRを挙げてもいいと思います。 あとの製品は、それぞれの個性を付け加えたようなものではないでしょうか。 あとデザイン性とかも、個人の好みがあるので、選ぶ楽しみは限りないと思いますが、 こと音質に関しては、文句のつけどころはありません。

er4srも所持しております。普段はヘッドホン派ですが、この音が無性に聴きたくなります。 srはリケーブルして使用しておりましたが、何度もコネクタを抜き差ししていたため接続が不安定になってきました。 しばらく他のイヤホンを使用しておりましたが、やはりこの音が恋しくなりました。 同じものを買い直そうとも思いましたが、若干の低音不足を感じリケーブルしていた所もあったので、xrをチョイスしました。 結果リケーブルは必要なくなりました。srの煌びやかな中高音に量感の増えた低音。非常に満足しています。 アンバランス接続なので音の拡がりはバランスほどないですが、しばらくはこのまま聴いていこうと思います。 ※ ケーブル交換は必要最低限にしましょう。あまり丈夫な端子ではないようです。

タイトルの点だけが残念です。 自分が購入したときは緑色を基調にしたパッケージでした。 最近（2021年4月に書いてます）パッケージ変わったなと思っていたら、製造国もアメリカからベトナムに変更になっています。 Etymotic Researchは、真面目に頑固にモノづくりするメーカーだと思っている。 何せこの値段で一台ずつ周波数特性のテストを実施していて、その証明として（担当者のサイン入りの）テスト結果グラフが添付されている。 だからこそ、このモデルの製造国は、本社のあるアメリカに拘ってほしかったなぁ。 せめてベトナム製にするなら、価格下げて欲しかったなぁ。 製造国も気にする自分としては、コスパ悪くなり、人に勧めづらくなった。 ［XSかXRか］ これまでイヤホンは「ER4S」しか使ってないぜ！という人はXSでいいのかもしれないが、 他メーカーのイヤホンも使う人には、低音強化のXRの方がむしろ「ノーマル」に聴こえると思う。

O produto em geral é muito bom. Todavia, as espumas dos fones que acompanham estavam amassadas e duras quando abri. Deixei elas aerando para ver se recuperavam a forma... mas elas continuavam deformadas. Testei um par, mas a dureza da espuma machucou o meu ouvido e a espuma simplesmente se soltou do tubo interno quando fui substituir pelas flanges de silicone. O certificado mostra que o produto é de 2019/2020, sendo vendido em meados de 2024... parece que envelheceu na caixa e o Amazon está desovando o produto velho no mercado brasileiro. Fiquei constrangido e decepcionado.

What can you say about Etymotic? I currently have two pairs of the ER4S, and owned the ER4B in the past. I have been using Ety products for at least four years non stop, and I absolutely love the ER4S, and consider if one of, if not the best headphone ever. Decided to try the ER4XR after reading the impressions on the forums at head-fi. At first I thought the ER4XR had slightly too much bass compared to the sound of the ER4S that I was accustomed to. They still have the classic Ety sound, but with a very slight bass boost. Because I was used to the sound of the ER4S, I cringed when I first heard the ER4XR. My immediate first impression, after hearing a couple of tracks I was intimately familiar with, was that the bass drowns out a very small amount of midrange detail (Compared to the ER4S). I immediately started thinking "oh no... what is Etymotic doing??". But you know what? After a few tracks, my brain adjusted and I absolutely love the ER4XR now, even on those tracks where my initial reaction was negative. I probably won't ever get rid of the ER4S, as I feel that on some recordings the ER4S is a bit better, but on other recordings, the ER4XR is clearly better. I was stunned when some tracks produced a lot more realism than the ER4S was ever capable of. When certain background vocalists would come on, or a certain instrument would kick in, the ER4XR's imaging and warmth really adds to the realism, and produces a sound much more natural than the ER4S. This isn't true across the board, but on a good 60-70% of the tracks I listened to. Some Etymotic fans, and other fans of neutral headphones may say that the slight bass boost makes these headphones "less neutral", and I honestly thought I would think the same thing, but I was surprised by the added realism, and now I can't help but think "if it brings more realism and texture to certain tracks, how can that be a bad thing? how can that be "less accurate"?" I've read some people who claim that the classic etymotic sound wasn't really neutral, but clinical. Now that they've provided a very careful, slight bass boost, it produces a sound much more akin to what the human ear expects to hear. According to this viewpoint, it's the ER4XR that is the first truly neutral Etymotic headphone. I haven't spent enough time with them to settle on a viewpoint, but I suspect there may be something to this. Something about these headphones just sounds more REAL than the ER4S, even if I know it's less "neutral", the overall effect this headphone produces tricks my brain into believing it's more real. There is so much music out there, all mastered using different studio monitors, by mastering engineers of various ages and skill levels. In my experience, the ER4S seems to be a better match for some music, while the ER4XR is a better match for others. Who knows why. Maybe it has something to do with the studio monitors used to master the tracks. Studio monitors are supposed to be neutral, but there are many models out there, all with slightly different frequency response curves. So if the engineer masters a track on a slightly warmer monitor, it might be better to play it back on a slightly warm speaker or headphone, and vise versa. I feel that, for some truly wonderfully mastered music, the ER4S is better than the ER4XR (I haven't tried the ER4SR), but for other music, the ER4XR brings out more realism and texture, without losing any detail. That's not to say that the ER4XR is a "forgiving" headphone, not in the slightest. It just has that slight bit of warmth that really bring an element of euphonic texture to the music.

Mit dem tiefen Sitz im Ohr kann ich mich anfreunden. Dazu allerdings nicht mit den 2-flange Aufsätzen. Ich nutze meist die großen 3-flange oder die großen gepolsterten Aufsätze. Der Klang ist für mich mit das beste, von dem, 'was ich mir leisten kann'. Sie sind recht neutral und müssen mit etwas mehr Power angetrieben werden. Bei mir ist das der Fiio BTR7 und der Khadas Tea Pro. Beide meist als DAC über USB-C am Android Phone angeschlossen. Als Musikdienst habe ich vornehmlich TIDAL im Einsatz. Der Klang ist 'flach', im positiven Sinne, aber unheimlich detailreich. Meine bisherigen Favoriten bei InEars sind die Tangzu Wu Zetian und Shanling MG100, wobei ich die MG100 angenehmer zu tragen finde. Die ER4 sind, wenn sie denn mal richtig und tief im Ohr sitzen klanglich sogar noch besser und der von vielen bemängelte Bass ist dann auch da. Ich würde mir dieses Modell auch wieder kaufen! Leider war das Kabel bei meiner Lieferung defekt und hatte DropOuts auf dem linken Kanal, wenn ich den Kopf bewegt habe. Also habe ich mich an den Support von Etymotic gewendet und ohne weitere Nachfrage ein neues Kabel zugeschickt bekommen. Jetzt kann ich die InEars richtig geniessen.

These are very impressive earphones. Bought in June 2025 for Amazon sale price of £193. I have not heard as accurate, exciting, detailed sound from any portable source before (in ear or over ear). They reveal everything about the music. I think they have enough bass (the ‘XR’ bit seems to deliver). The isolation is good, not as good as active noise cancellation but with ANC you get strange artefacts and a kind of ‘wash’ over the sound. With these, you just hear less of the world because the fit is so snug. On the fit. If you read some reviews you will probably be a bit scared (I was). In reality, they don’t go extremely deep. A little deeper than usual earphones but not uncomfortable. Takes a small amount of getting used to. Because music sounds so good, I kept putting them back in! So they can’t feel that bad. Soundstage is narrow because of the fit. But you can hear everything in its proper place in the stereo field. I’d 100% recommend. If money was no object, then they are still very much worth it at full price. They have lots of excellent box candy too, including a graph showing how well matched the two individual earphones are. Bravo.

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.
