My problem with the sonys are that they distort at volumes too low for me to enjoy while all the senn 5xx cans I've tried has never had that problem.

That sounds like either a defect or an amp/headphones mismatch.   I use my MA900s out of the headphone jack of a 330watt amplifier and no distortion.

Actually a lot of parts on the MA900 that look like plastic at first glance, are actually thin metal.  The headband doesn't seem particularly fragile.

The tape is just at the point where the slider exit the headband, which is a loose and wobbly connection.  By taping it, you provide a more solid framework for the driver to push against, which makes the bass a little more solid.

(The MA900 is an odd product - a large amount of research went into the design of the driver enclosure, which has IIRC a patented bass enhancing design.  Then, after the prototype was done, for some reason it was implemented as the top end of a super-cheap product line with cheap materials, rather than a premium product competitive with the HD600 and K701.  Of course, only Sony employees know what happened...)

Its weird though because both drivers distort at the same volume making me rule out that its a defect. Unless they have matched defective drivers LOL

Just received a brand spankin new hd518. A little bright out of the box but from my experience with senns, my guess is that this bright sibilance goes away in time. I'll run it in overnight with some random music and tones and see if there is a difference within 8 hours or so.
