The good impression continues in the materials and workmanship, here come brushed aluminum and fine Alcantara used. Makers may miss the leather often used for high-quality headphones, but I think that's breathable and anti-slip Alcantara as even more suitable in its properties. It is just on very warm days not unpleasant on the skin. Something unpleasant the pressure that the strap exerts on the ears. This is too much for my taste a bit. However, this is probably an issue that all supra-aural headphones over the circumaural, since they also have to keep. But that's about criticism at a high level, all in all, the momentum is comfortable to wear even over a longer period.
On connecting cables without cloth coat, but this is not really a disadvantage, there is a 3.5 mm jack for smartphones and tablets and a remote control with buttons for volume and call acceptance and a microphone. However, the remote control does not seem to be compatible with all devices, with my Motorola smartphone with Android 4.4.4, it is not working. According to Sennheiser website, it is suitable for the Samsung Galaxy, LG, HTC, Sony and other Android devices as well as iPhone, iPad and iPod. The cable is also connected to the headphones via a connector and not fixed, it can therefore be replaced if necessary.
Practical and therefore suitable especially for mobile use of headphones is its foldable earcups. The adjusting bars with the earcups can be folded inwards, thus making the whole thing a lot easier to handle and can be stored with bags so in the bag supplied. The bag as well as the pure Containerboard are nicely styled and make a quality impression, which makes the Momentum also a beautiful gift for music lovers.
All in all, the Momentum headphones, which can especially convince with its sound qualities and is particularly suitable for mobile use. It can be folded to save space and is visually unobtrusive elegance. You can see that's not the same as a marshaller on the airfield from. The music is still well shielded from the outside, the person sitting next to on the bus or train is therefore not harassed unnecessarily. For the domestic musical enjoyment I would still prefer circumaural headphones, they are just, if you are wearing a long time, even more comfortable than supra-aural.
