The longer length of the Senn's may bother people like myself who suffer from TMJ syndrome (jaw problem due to clenching), which may also be further induced by its vice like pressure.

Some people may prefer headphones with more thumping bass, but I tend to avoid that so I can hear the clear highs.

People have described the bass as lacking in these

Not THAT many people have an actually decent sub, and barely anyone realizes what soundstages or resolution mean for the listening experience, so using these instead of my better resolving and more dynamic headphones actually benefits the people I'm mixing audio for

but I suspect most people will find it quite comfortable

Same issue as the other people report: the plastic handle broken.

Many people complain about the "lack of bass", but theirs a big difference between mudding up the rest of the sound spectrum with bass and being able to handle low end, and these do the later perfectly.

Some searching and you'll find other people have had similar issues with a bad connection
