Pros: excellent portability, rugged design, clear and boomy bass and mids.
Cons: treble can sometimes sound unatural and pitchy, very uncomfortable after half an hour, you need to wear it right to get the bass.
Writting this out of utter boredom...
Im an audiophile by nature and appreciate every bell and whistle that comes with a product. Been usin these for around half a year. Had to use the warranty once after the wire snagged onto a table which cause the left speaker to fail. First time it actually failed like that cause most other times it'd pretty much pull my phone out of my hand :P guess i got it to its breaking point which i often do with anything XD
I got em at a discount but, based on sound quality alone, sennheiser did not disappoint. They can get pretty loud if u want em to. Not to say they're overpowered. Just right i guess. These were built for those on the go and appreciate above mid level sound quality. But if u want more sound quality on the go than go get sennheiser's hd448 or others of the same caliber. You'll lose portability but hey there's no compromise for sound quality from a larger driver, not to mention how much more comfortable they'd be :P
If you're a bass maniac who wants portability than these cans shud be ok for you. Not just right but ok cause generally speaking, apart from the on ear design, they'd cause some strain on your ear drums and canals which i pretty much think is due to the sound pressure. Well if u use em for more than 45mins at 70% and above from the max volume. They'd handle pulsating rock, RnB and hip hop pretty well. The treble can get very pitchy and unnatural on certain songs and/or Eq settings.
Out of the box, the highs were persistent while bass and mids were abit shallow but after some burn in time a few weeks of wear and tear they balanced out each other and the pitchy treble lowered quite alot but its still there though, just not so prominent. The cups manage a pretty decent job in outside noise isolation not on par with active noise cancellation but more than enough. like i said above, you'd need a little wear and tear for the cups to actually soften up enough to mould onto your ears and effectively cancel most high frequency ambient noise.
Another thing is that ambient low noise, i.e engine hum on the bus, will severely dampen the bass causing it to actually blend with bass guitars or other bass instrument/sound in the song. Well its no surprise though i mean they are relatively small so there's not alot between your ear-speaker-and the outside.
These cans were built around portability for people on the go and on that basis it definitely scored an A. The metal strip on the headband seems to do its job well although i do feel the plastic will snap easily of u put some effort into it :P comes with a volume adjusting thingy, not sure wats it called lol, which is pretty useful especially if ur usin iPods or iPhones since they're pretty much fixed on volume so these volume adjustable thingys offer a good degree of volume control. The pads on the headband offer some comfort but due to its light weight design you'd barely notice em. You can practically shake your head like an arse and it'll stay on your head with close to little to no headphone movement. Like i said, portable rugged design... :P
Well simply put, they're more of 'put sound in your ears while u move from A to B', in this case A to B would be like goin to the shop across the street and back home. They're comfy for about 10 mins ONLY. Well thats my opinion. In which case they'd do fine for people on the go who wants to kill time with music.
Nothing's perfect and there's a reason why there's thousands of different headphones on the market each purpose built. If ur the music lover always on the move and you want sth that blocks some ambient noise, rugged in design than go grab the px 200-II or some other model of the same caliber :P just do you research....
