So I've owned a pair of Sennheiser HD555's for about 4 years now and while they haven't broken in any way, I'm looking to buy another pair of Sennheisers that are more portable than the HD555's (10 ft. cable and bulky 1/4 inch jack + open design -_-) I've been considering 2 choices in the Sennheiser 400 series. The HD439's and the HD449's While I know they are both very similar, there are big differences in my opinion. HD 439's: I really like the detachable cable on these, and I've always been in love with the cloth ear pads from my 555's, so i know these would be super comfortable. Also these present a bit more bass than the others in the 400 series, which i don't know if I'll enjoy, because I really only have the HD 555's to compare audio quality to. HD449's: These headphones are apparently a bit more powerful than the 439's because of stronger magnets in their monitors, which is a plus because I mostly listen to music on my laptop, phone, or zune (YES I SAID IT AND I SAID IT PROUD--ZUNE). Also I'v e heard that they have a better range of sound quality not just regarding the bass and treble. The one thing that scares me to death about these cans is the pleather or "leatherette" material for the ear pads. While i know that these are better at blocking outside noise, I can't help but feel like they'd be very uncomfortable. The only other cans i've used with the pleather are the Bose AE2's, so one question is how do they compare? also to beats leather pads? In general, I listen to a broad range of music from classical to rap to indie rock. Pretty much anything but country. I like to have a bit more bass and high tones than mid, but not too much. For this reason, I think the HD439's would be better in regards to sound quality and better design/comfort. The only thing that keeps me looking back at the 449's is the offer of more powerful magnets and better sound when playing from a mobile device or something with a low power output. I also really like the fact that even if i do like lows and highs better, I can always put an equalizer on the HD'449's to tailor their more balanced sound to my wants. But I'm still afraid of the comfort the 449's offer compared to the cloth pads of the 439's. Again I own a pair of Sennheiser HD55's and love their sound quality and comfort. I also own a pair of AKG K181DJ series, but those are mostly for listening to house, dubstep, and drub&bass.; I've owned the Bose AE2 (second edition) and have used beats studio for a time. These are really all of my reference points for sound quality and comfort. Anyways, I digress. I'm very torn between the two and I've given all of the info I can. Any suggestions/ratings/opinions would be greatly appreciated.
