SONY / WF1000XM4 SM

Variations

The SONY/WF-1000XM4 is a Bluetooth true wireless earphone that features industry-leading noise canceling function, supports the high quality codec LDAC, and allows you to experience high-resolution sound quality.

Scheduled for release on June 25, 2021 ■Industry-leading noise canceling performance (※1) ・The WF-1000XM4 reduces noise that reaches the ears over a wide frequency range, from low to high frequencies, providing even more silence than the WF-1000XM3. You can now feel quieter even in noisy environments such as airplanes and buses, as well as in environments with a lot of people talking, such as in the city or cafes. ■Sony's first fully wireless earphones with high-resolution support ・LDAC support allows you to enjoy high-resolution sound quality (※2) even when wireless. In addition, with DSEE Extreme (※3), you can enjoy high-resolution (※4) high-quality sound from various compressed sound sources such as CDs, MP3s, and streaming on Android and iPhone. ■Comfortable calls in any environment ・Equipped with voice pickup technology that optimally controls the microphone and sensor and performs advanced voice processing. Beamforming technology and bone conduction sensors capture both the voice emitted from the mouth and the voice transmitted by the vibration of the skull, and collect your voice accurately and clearly even in any noisy environment. ■High wearing stability and comfortable fit ・Utilizing the data on ear shapes from various countries that we own, we have created a shape design that does not interfere with the unevenness of the ear. We have created a holding method that fits the shape of the ear and supports the earphone body with the contact surface inside the ear. In addition, the noise isolation earpiece has a holding force in many directions, achieving a higher wearing stability and comfortable fit. ■Long battery life that is safe even when you are out and about ・When noise canceling is ON, you can use it for 8 hours on the main unit alone, or for a total of 24 hours (※ 5) by charging twice with the included case. In addition, when noise canceling is OFF, you can use it for 12 hours on the main unit alone, or for a total of 36 hours (※ 6) by charging twice with the included case. It also supports quick charging, so you can feel safe even when you suddenly go out. (※ 1) In the market for completely wireless noise canceling headphones. As of April 26, 2021.

スタッフレビュー

SONY完全ワイヤレスイヤホン『1000Xシリーズ』の第4世代となるWF-1000XM4。

デザインも前モデルから大幅に変更され、耳の収まりがより良くなった印象。
充電ケースのサイズも非常に小さく改良され、これなら持ち運びしやすいですね。アプリの便利さは前モデル同様。EQはノイキャン、アンビエントモードの調整など細かな設定を行えます。サウンド面では、奥行きを感じられる立体的な音場、クリアな高域ながらも「さ行」が刺さらない、非常に聴きやすい音質です。

EQを調整すれば、低域の効いた迫力あるサウンドも楽しめる、万能型ワイヤレスイヤホンです！

期待値を超える音でした

投稿者名Reviewed by：KAY 【千葉県】

初めてのワイヤレスイヤフォンですが、音に拘りを持っている以上は高級品しかないと決めてこの商品を購入しました。イヤフォン内部の構造やそこでどんな処理がされているのか技術的な知識もあるので、こんなちいさなスペースで”それ”ができちゃうのに驚きました。低域から広域までクセのない音を作り出していることは高く評価できます。
密閉型のSONYのスタジオモニターも使っていますが、こちらは音を出すスピーカーにあたる部分がイヤフォンに比べて巨大なので良い音が出るのは当たり前ですが、あえて比較するならば、WF-1000XM4は奥行き感、音の滑らかさなどはどうしても劣ります。
しかし、繰り返しますが、ワイヤレスイヤフォンの物理的な制約を考えたら、十分に満足できる音です。
なおノイズキャンセリングについては比較するものを持っていないので評価は控えます。
