I have Sennheiser HD 598 and HD 2.30g. The HD 598's are connected to my desktop and I would most likely not replace these, had them for years and love them, but would test them out as potential. The 2.30g however would get replaced easily, getting worn out and wired only. Been looking at wireless headphones for a while but never dropped the money. Would be nice to finally get wireless for more portability with my phone, tablet and laptop. Would use it for music, podcasts, youtube videos and conference calls.
