Welcome to the future... where audio devices will be wireless. Now your music will sound crappier on your ridiculously expensive Bluetooth headphones connected to your Bluetooth-only device. Cables? That is so 1900's.
It's sort of sad for me to think of a future bringing technology which is worse than what we currently have, in terms of both usability and quality of sound. I'm not a audiophile, use either a set of Ministry of Sound MOS006 for on the bus or... near any people I want to not hear and a set of Sennheiser PX100 collapsable ones if I want clearer sound but slightly less... ear bleedy! Still tho, in comparison to blue tooth sets I've tried which have been 3x and 4x the price I got mine for, the clarity of the Sennheiser and the sheer volume of the Ministry pair can't be beaten not to mention of course the lack of interference potential from 3.5mm jack and not having to worry about charging my headphones seperately.
Also when it comes to bluetooth headphones having no cable, the Ministry of sound set I have come with a jack at both ends, so yeah if I'm walking into a job I can just as handily pull the cable from the headset and put the cable in my pocket or the PX100 pair fold into a case no bigger than a glass's case. convience need not cost every bit of quality and definitely does not need to cost €200+ :< that's just clueless buying imo.
