so, there is a website where i get points for doing surveys and i get whatever i want from amazon when i get enough points. and i want to choose between bose ie2 and sennheiser cx 880. i have tried bose and they sound amazing and loud, but i dont get as much bass as i get on my 2 year old sennheiser cx 400 ii. since i haven't tried CX880 i dont know what to choose. If you have tried them BOTH, please let me know what you've liked more, and what characteristics are better in each ones. Thank you.
