Frankly I was very disappointed by the strength of this product, which is far from the reputation of technics. With the RP F400, allow at least one tube of glue or super glue Araldite because arcveaux are extremely fragile, and if they survive, the plastic will dry out and become brittle literally.
Mine has the two poles of left broken, and now the left has just broken.
As against the wire has survived strokes noumbrex CHIS, q'il I believe will end up in my conection to reserve, but for ca € 50 is an expensive shielded cable and mini jack

Maybe the quality is corect for this type of product, but obviously the rest is in Chinese products: disposable after a few months.
