Noise cancelling experience

In terms of noise cancelling experience, U&I Pure true wireless earphones support ANC/transparency mode and ENC dual mic call noise cancelling to meet the usage experience in different scenarios.

The ANC function adopts the DSP digital noise cancelling solution, which picks up the ambient noise in real time through the noise cancelling microphone, analyzes the audio information with the ANC software algorithm, and sends out reverse sound waves through the speaker to achieve accurate noise cancelling effect.

In use, the physical noise cancelling effect brought by active noise cancelling and closely fitted eartips has a very obvious inhibitory effect on medium and low frequency steady-state noise. The moment the active noise cancelling is turned on in the office, the humming sound of the air conditioner is stopped on the spot. For streets and subways with complex sound information, it can also greatly reduce the impact of external sounds and provide a more tranquil music experience.

The transparency mode also picks up external sounds through the noise cancelling microphone, and after algorithm processing, compensates the sound heard by the human ear wearing headphones through the speaker. After U&I Pure turns on the transparency mode, the listening effect achieved by the superposition of the two sounds is natural and comfortable, and it can be seamlessly connected with the external sound without removing the headphones.

The advantages of the noise cancelling function are mainly reflected in two aspects. On the one hand, it can present clear audio effects to the person talking to it. On the other hand, it enhances its own privacy. U&I Pure earbuds has a built-in dual microphone unit to achieve more accurate sound pickup, and with the ENC call noise cancelling algorithm, it can effectively reduce the environmental noise during the call and ensure the effect of clear voice calls.


Sound quality of U&I Pure

At present, the in-ear headphones on the market can better demonstrate the bass effect due to the way of listening deep into the ear canal, so large-sized units are no longer used in the application of units. But also because of this, the sound field effect of the audio is also limited.

While U&I Pure earphones adopt the in-ear method, they are still equipped with a 12mm dynamic driver, and use a composite fiber PU+LCP diaphragm to further improve the response and strengthen the flexibility of the diaphragm. In the music experience, the most notable features are the low frequency shock and the wide sound field. The audio performance is powerful and crisp, the bass is natural and full, and the mid- and high-frequency vocals are clear and loud.

In addition, the U&I Pure true wireless earbuds also supports AAC high-definition audio decoding. When used with iPhone and other mobile phones that also support AAC codec, it can also provide richer audio details through higher bit rate transmission.


Charging and Battery life

In terms of charging, the U&I Pure true wireless noise cancelling earbuds adopts the Type-C charging interface, which is compatible with the current mainstream Android mobile phone charging cables, and does not require additional charging equipment when going out. It also supports wireless charging, providing a more convenient charging method.

In terms of battery life, the official data shows that the music playback time is more than 3.5 hours at 50% volume, and the charging case can also charge the earphones 2-3 times.
