If you have bought this pair of headphones recently please give us some feedback on the reliability of the product. Has the quality and quality control increased ? Or does this particular Focal product still has issues with quality, reliability and quality control? It seems that this product in particular has had many issues, which is not the case with other Focal products (Clear, Celestee, Utopia, Stellia etc.) Issues with Elex seem to have to do with defective driver coil failures (design issue?), defective cables and leaking (glue) headbands.
