SONY / MDREX31BNB

Variations

Digital noise canceling cuts out approximately 98% of noise. Wireless stereo headset with one-touch connection (NFC).

■ Equipped with Bluetooth Function
- Compliant with Bluetooth standard version 3.0 for easy operation and reduced sound dropouts due to surrounding radio waves. Pairing with a Bluetooth-enabled Walkman, iPhone, Xperia, or other smartphone or mobile phone enables wireless music playback and hands-free calling.
■ Equipped with One-Touch Connection (NFC) Function
- One-touch connection, Bluetooth connection, and power-on are possible with one touch using the NFC (Near Field Communication) function.
* To use the One-Touch Connection (NFC) function, an NFC-compatible smartphone or some Osaifu-Keitai®-compatible Android™ smartphones are required.
* Some smartphones require the installation of the ""NFC Easy Connection"" app.
■ Wide Range of Audio Codecs (Supports aptX/AAC)
- Supports aptX in addition to SBC and AAC, allowing you to enjoy a wide range of audio codecs.
■ Echo Cancellation: Reduces the amount of audio from the headphones included in the audio picked up by the headset microphone, suppressing echoes on the other end of the call.
・Noise suppression: By suppressing noise picked up by the headset microphone, the noise heard by the other party is reduced.
■ Digital noise canceling function reduces ambient noise by approximately 98%.
・Noise canceling function is significantly improved thanks to precise filter characteristics not possible with analog. The digital equalizer achieves ideal frequency characteristics, reproducing high-quality sound in quiet environments. You can also switch filter characteristics to control the amount of cancellation to suit the different characteristics of environmental sounds depending on the situation. This makes high-precision noise cancellation even more effective.
■ AI (Artificial Intelligence) noise canceling function automatically selects the optimal cancellation mode with the push of a button.
・The filter circuit that controls the amount of cancellation has been digitized and controlled by software, allowing you to switch filter characteristics. With the push of a button, ambient noise is analyzed and the optimal mode is automatically selected from three options. Effective noise cancellation is achieved to suit the various noise characteristics of each environment.

迷ってるならコレ

投稿者名Reviewed by：メビウス【大阪府】

安いワイヤレスイヤホンと比べると、耳につけた瞬間から違いが分かります。周囲の環境に合わせてノイズキャンセルを掛けれるのは便利です。室内で、使用すると、ほぼ人の会話は、聞こえません。ブルートゥース接続も、スマホ、パソコン共に。途切れる事は無く、遅延もありません。この価格帯の中では。最強です。迷っている人は、まずこれを試してみて下さい。お勧めです。
