Re: BOSE QC II Noise Cancelation is HORRIBLE
i'm too facing this problems. i bought mine one year ago. Noise Canceling was great. Unfortunatly i did all the firmware Updates up to 4.5.2 At some point the "Ear-pressure" went down (in the beginning i couldn't use them longer than 3 to 4 hours). But since then i - as MANY other - face the same problem. Voice is cleary hearable, even constant background noise like a vacuum cleaner is NOT filterd out anymore.
this has in my opionion NOTHING to do with pairing oder other 1 level support tips. Its definitly the firmware.
give us the option to DOWNGRADE the firmware. It is the best and imho only way to find the point where it went wrong.
