LOW: Depth and unparalleled clarity. No saturation. If you like low "natural", this will delight you.
ACUTE: Even if the bass is perfect, this prevents that at high frequencies there is the highest level. This is the case here.
The big downside is the strength of the product. I had concerns about the height adjustment of the helmet and the jack connection. But this is probably related to a defect that is not general! You still have to pay attention to it.
In summary, I would still highly recommend this product.
