Manual of product H-20B
Editorial note
The Lasmex H-20B headphones stand out for their immersive sound quality, thanks to a frequency range of 20 to 20,000 Hz and a sensitivity of 118 dB, which ensure clear and powerful sound, perfect for enjoying your music or podcasts. Additionally, the in-ear coupling provides prolonged comfort, making these headphones ideal for long-term use. However, some drawbacks are worth noting. The weight of 340 g may be considered relatively high, which could lead to discomfort during extended use. Furthermore, the Bluetooth 2.1+EDR technology, while offering connectivity, is now outdated compared to newer versions, which may affect the quality of the connection with modern devices. The microphone sensitivity of -42 dB, while acceptable, may not be sufficient for high-quality recordings in noisy environments. Regarding battery life, the 320 mAh allows for 8 hours of talk time, sufficient for daily use, but this may not suit heavy users looking for extended autonomy. Finally, while the modern and sleek design of the headphones caters to various tastes, the in-ear coupling may not necessarily be everyone's choice, with some preferring over-ear models. Overall, the Lasmex H-20B offers a pleasant audio experience with solid performance, but users should consider their specific needs regarding weight, connectivity, and battery life before making their choice.Score details
