First page image of the manual for LIVE 400BT

The JBL LIVE 400BT headphones stand out for their excellent sound quality, with a frequency range of 20 to 20,000 Hz and a 40 mm driver, providing an immersive listening experience rich in detail. Their impressive battery life of 24 hours of continuous playback allows for extended use, ideal for active users. However, some drawbacks deserve to be highlighted. Although Bluetooth 4.2 technology ensures effective connectivity, it may limit compatibility with newer devices. Additionally, the nickel-metal hybrid (NiMH) battery may require more regular maintenance than lithium-ion batteries, which could be a disadvantage for those who prefer simplicity. The weight of 185.8 g may also be perceived as slightly heavy during prolonged use. In terms of design, the red model is modern and attractive, but it may not suit all tastes, with some users finding it too flashy. Finally, while the touch control is intuitive, it can sometimes lead to errors, especially in moving situations. Overall, the value for money is satisfactory given the audio performance and battery life, but considerations related to weight and battery technology could influence the overall perception of this product.
