I bought this headphone dernirement. The shape of my ears does not allow me to use all the headphones, as many slide. The CX 300 perfaitement remains in the ear and also it comes with three games caoutchous sizes Different.
I find the sound quality fairly good condition with a good dynamic to use a low qualiseur as issued by the latter are impressive given the small size of the product. It insulates well from outside noise is almost that can become dangerous with traffic routire and can also be enjoyable in the transport (bb crying).
