Editorial note

The JBL Live 670NC stands out for its optimal comfort and sound immersion, made possible by its active noise cancellation technology. The user experience is generally very positive, particularly due to an impressive battery life of 65 hours of continuous playback, making it an ideal choice for long days. However, although the headphones offer excellent audio performance, Bluetooth connectivity can sometimes suffer from interference in crowded environments, which can affect sound quality. Additionally, the weight of 219 g may be perceived as relatively heavy for prolonged use. In terms of features, compatibility with Google Assistant and Amazon Alexa enhances the experience, but the lack of a dedicated companion app for personalized settings is a notable drawback. Finally, while the built-in microphone is convenient for calls, it does not provide the same clarity as an external microphone, which can limit communication quality. In summary, the JBL Live 670NC is an audio headset offering excellent value for money with remarkable comfort and battery life, but it has some limitations in terms of connectivity and microphone.
