Manuals of product MM 400-X
Editorial note
The Sennheiser MM 400-X stands out for its immersive audio quality, thanks to an in-ear coupling and a closed acoustic system that allows for full enjoyment of music and calls. Weighing just 105 g and featuring a foldable design, these headphones provide appreciable comfort during your travels. In terms of connectivity, the Sennheiser MM 400-X is versatile, allowing both wired and wireless connections via Bluetooth. Battery life is also a strong point, with a talk time of up to 20 hours, although the continuous audio playback time of 10 hours may be insufficient for some users. However, the weight, while reasonable, can become uncomfortable during prolonged use for some individuals. Additionally, the Bluetooth 2.1+EDR technology, while effective, is relatively old and may limit certain connectivity features. The built-in microphone, although effective with noise cancellation, can pick up surrounding noises, which could affect call clarity in noisy environments. In conclusion, the Sennheiser MM 400-X offers good value for money, but some drawbacks, such as the lack of a 2.5 mm connector, could restrict connection options for users. It is a solid choice for those seeking headphones that provide an immersive audio experience and transport comfort, while being aware of potential limitations.Score details
