Very good sound despite engine!

So I bought myself recently DIESEL VEKTR that yes cost significantly more than the Crusher.
A friend told me this then borrowed in order to compare them with each other.
The first thing you notice:
Crusher: Over-Ear
VEKTR: On-Ear
Both ear cups can be but comfortable to wear, the not mount the crusher so firmly and naturally are much larger.

Sound:
The crusher has not necessarily a particularly large diaphragm that produces the bass. Instead, a vibration motor is used, which requires a separate battery.
Although this is only a vibration, the bass by listening to but more intense.
If you do not know that it only comes from the engine, you would immediately say that the sound is also clearly better, so from the more expensive diesel VEKTR, which incidentally already sound quite good.
When listening closely to the bass is naturally not as differentiated as in higher value earphones, yet convinced of the sound, as well as the bass.

Disadvantage:
The built-in motor and the battery are slightly heavier than ordinary headphones.
The diesel VEKTR can easily wear at the gym or while jogging.
Crusher, however impossible not to feel rather on weight. In addition, you can hear the clack engine while jogging.
Why only 4 stars. Otherwise for the price very good headphones!
