与前代QCC512x系列和QCC30xx系列相比，此次发布的QCC514x系列和QCC304x系列均能够提供更稳健的连接、更持久的电池续航、更高的舒适度，同时还集成专用硬件以支持高通的混合主动降噪技术（Hybrid ANC）、语音助手和顶级的无线声音与语音品质。下面来详细了解一下：

Compared with the previous qcc512x series and qcc30xx series, the qcc514x series and qcc304x series released in this release can provide more robust connection, longer battery life and higher comfort. Meanwhile, special hardware is integrated to support Qualcomm's hybrid ANC, voice assistant and top wireless voice and voice quality. Let's learn more about it:

1、Qualcomm TrueWireless Mirroring 技术

1. Qualcomm true wireless mirroring technology

QCC514x系列和QCC304x系列SoC将会支持Qualcomm TrueWireless Mirroring技术。该项技术让一只耳塞通过蓝牙无线连接至手机，另一只耳塞则成为其“Mirroring”（镜像），并且这两只耳塞可以在多个使用场景下快速切换。

Qcc514x series and qcc304x series SOC will support Qualcomm truewirless mirroring technology. The technology allows one earplug to be wirelessly connected to the mobile phone via Bluetooth, and the other earplug becomes its "mirroring", and the two earplugs can be switched quickly in multiple use scenarios.

例如，从耳朵中取下和手机相连的耳塞之后，用户无需任何操作，Mirroring耳塞便能接管与手机的连接，避免了音乐或语音通话的连接中断。

For example, after the earplug connected to the mobile phone is removed from the ear, the mirroring earplug can take over the connection with the mobile phone without any operation, avoiding the connection interruption of music or voice call.

Qualcomm TrueWireless Mirroring还支持管理单一蓝牙地址，在用户将两只耳塞与手机进行配对时，手机仅显示一只耳塞设备以进行配对。

Qualcomm truewiireless mirroring also supports the management of a single Bluetooth address, and when users pair two earplugs with their phone, the phone displays only one earplug device for pairing.

2、集成式混合主动降噪技术

2. Integrated hybrid active noise reduction technology

QCC514x系列和QCC304x系列SoC均采用了集成式混合主动降噪技术。通过支持外部环境音的超低时延透传，SoC所集成的ANC专用硬件能够对周围环境进行真正自然的感知，使用户不仅可以在飞机上使用ANC，还可以在运动、办公等日常场景中使用。

Qcc514x series and qcc304x series SOC adopt integrated hybrid active noise reduction technology. By supporting ultra-low time delay transmission of external environment sound, the ANC special hardware integrated by SOC can truly sense the surrounding environment, so that users can not only use the ANC on the aircraft, but also in daily scenes such as sports, office and so on.

3、超低功耗、超长续航

3. Ultra low power consumption and long endurance

取决于设置和其他影响因素，通过优化QCC514x和QCC304x SoC可以在不同用例中支持业界领先的低功耗，65mAh的电池可支持长达13小时的播放时间。现在，启用ANC对电池续航影响甚微，更长的电池续航让消费者可在国际航班或长时间办公中享受卓越音质。

Depending on the settings and other factors, the qcc514x and qcc304x SOC can support industry-leading low power consumption in different use cases, and the 65mah battery can support up to 13 hours of playback time. Now, the use of ANC has little impact on battery life. A longer battery life allows consumers to enjoy excellent sound quality in international flights or long hours of office.

此外，更长的耳机续航时间也可以允许使用更小的充电盒电池和更紧凑的设计让耳塞更容易携带。

In addition, a longer headset life also allows for a smaller charging box battery and a more compact design to make the earplugs easier to carry.

4、语音助手唤醒功能迎来全面普及

4. Voice assistant wake-up function ushered in comprehensive popularization

面向旗舰产品的QCC5141特别针对多个语音生态系统提供始终在线的唤醒词激活，比如亚马逊的Alexa、Google Assistant等语音助手；

Qcc5141, a flagship product, especially provides online wake-up word activation for multiple voice ecosystems, such as Amazon's Alexa, Google assistant and other voice assistants;

面向入门级和中端产品的QCC304x系列能够为多个语音生态系统提供按键语音激活，助力OEM厂商以更快速度、更低成本实现对语音助手功能的支持。

Qcc304x series for entry-level and mid-range products can provide key voice activation for multiple voice ecosystems, helping OEMs to support voice assistant functions at a faster speed and lower cost.
