Alright i am stuck between choice, my current razer blackshark headphones are slowly dying and i am looking at a future pair for when they eventually die. i am looking at using bluetooth for my new pair as i am not a huge fan of my cable getting stuck. i have already looked around and i am wanting a good pair for music as i listen to a lot of it (and considered active noise cancellation as i wanted the peace when on public commute). i have looked at the Steelseries Siberia 800 (gaming type) because they fit what i wanted except they don't have ANC and also have looked at the Sennheiser mm 550-x (music type) as they have ANC and fit the rest of the specifications, if you could help me choose between them, have any other pairs you think i might like or even just some advice on what would work, please let me know, Thanks
