dunno about wireless headphones but,the Audio Technica AD700 suggestion was purely based on budget considerations.honestly,for the price they are going,i dont think it has too much competition.the M50's are a little pricier.now as for whats better,i would just say,the AD700's supposedly have a great soundstage due to being open,hence the bass impact is less.there,but less.the M50's are closed,so smaller soundstage,but great bass impact,particularly excellent sub-bass, and very neutral.for someone who listens to jazz etc,the AD700,full stop.just dont expect to listen to trance and wonder why they dont sound as impactful :indifferent14:.i listen to everything,indian classical to a lot of EDM/PSY(yeah,very all encompassing tastes,),so the closed M50's made sense.cheers
