Hey! I've got a question, please help. I recently purchased this cable:

A 3.5 mm to 6.3 mm cable "extension". The idea was to get an angle 3.5 plug to use instead of the big connector that comes with my M50x, which produces a huge torque over my DX50 phone out (I don´t want to break it!). First thing I search for was an angle Adapter or an angle plug 3.5 to 3.5 cable (male to female) but I could´t find any of them anywhere (physical stores). So I figured "I´ll just buy this one and use it with the 3.5 to 6.3 adapter that comes with the M50x". Both of very good quality, so I assumed the sound would be the same. Well, I was wrong, cause the sound quality is really bad! The funny part is that I tried a much cheaper way before this, using a AUX cable (with much smaller plugs) and a double female 3.5 adapter. Not very pretty but it didn´t affect the sound quality, at least not like this new (and more expensive) cable.
So, What should I do? Is there a better solution so I can keep the SQ and decrease the torque of the original cable? I can't replace it cause of the propietary lock system and I don´t really know why this -not cheap- cable works so bad. Or maybe is just the volume what changed and not quality?. That´s hard to believe after what I could listen.
Thanks!
