Sennheiser MM 400 Bluetooth

Sennheiser MM 400 BluetoothGet a unique sound and a superior clarity

Higher quality when it comes to the clarity of the sound and that of the bass. It provides wireless freedom and the Bluetooth technology allows telephone connection.


The microphone is not properly functioning and there are often delays at the level of the Bluetooth technology. Also, there are some controls that are not compatible with iPhone.

While you get the feeling that you are only using headphones from time to time, the Sennheiser MM 400 Bluetooth headset still makes a great investment for those who long searched for the device that delivers great sound quality. The invisible microphone could have been a major advantage, but the fact that the user encounters problems when using it lowers its practicality.

Sennheiser MM 400 Bluetooth Headsets

Enjoy great optimized hi-fi stereo sound

The new Sennheiser MM 400 Bluetooth headsets offer the possibility to both make calls and listen to music. With the help of an integrated invisible microphone, one can easily use MM 400 to talk in a comfortable manner. However, the microphone is full of surprises and this useful feature can become unusable at times. When it comes to how long can the headsets’ user talk, the product offers a talk time of around 20 hours.

The product also includes features and controls meant for playing games and watching video on the iPhone. As it is a full of surprises device however, MM 400 comes with difficulties when it comes to these activities too.

Sennheiser MM 400 is a great choice for those who travel a lot as it works both wireless or wired, in case of no Bluetooth accessibility. More than that, it can be compacted so that it won’t take too much space when carried. The German company Sennheiser did a good job with this model when it comes to portability, comfort while wearing the device and a great transmission signal, but failed to provide the product with the promised standards in terms of using it for communication.
