no they're not
sennhiesers are trash
sennhieser represent here.
i've been using a pair of their gaming headphones and they're the best headset i've owned
ever.
yes they're like $300 bucks but the build quality is amazing, they sound great, very comfy cloth pads, and the microphone doesn't sound cheap either.
the mic sounds very similar to a blue snoball, not a cheap mic with sound leakage (it happens with me because open back which is awesome btw)
their site is very lacking to the 2014 standards of web design but don't bash them because their site "sucks." when sennheiser says "dj", they're actually trying to market it for djs. they're a serious company that does audio tech for venues and studios, not a stuffty company that just says they are dj headphones but in reality it's just a ploy for kids who think dj makes them better.
EDIT:
They are indeed. Sennheisers headphones are all severely overpriced plastic-tastic toys that sound overly warm and unrefined. This only stops being true at about the $1500 price point, the HD800, and even then a $200 headphone is really close to its performance.
they're really not. are you sure you're not talking about beats? oh btw, the HD800 won't work on a mobile phone since it has a
1/4inch stereo jack and it requires a powered headphone jack to run it.seriously you gotta look up these things and determine if they're really good or not. best case is to actually try out the product first and then choose to buy or not.
tl;dr: sennheiser is a VERY respectable company and not a stuffty beats rip-off.
ANYWAYS. this is for OP. $100 dollar for headphones? what i did was i bought IEMs because i like the portability, but if you do prefer headphones, go for the sennheisers. they're cheaper and lack some of the things that the higher end models have (open backs, cloth pads) but work for mobile purposes since you won't need a powered headphone jack.
audio technica does good things too, but the build quality is kinda poop. the last thing i tried headphone wise from them was very plasticky and i'm not a guy who likes cheap plastic on my head.
another company would be AKG. one of their best headphones are on sale right now for
$69.
http://www.amazon.com/AKG-240-Semi-Open-Studio-Headphones/dp/B0001ARCFAi'd say that's a better deal and WAY better sound from the cheap-o sennheisers. with audio, when you do spend more you will see a difference in quality with cheap vs premium products. (compare the list prices not the actual prices for my little known fact there. yes you might be able to get really good headphones for cheaper and that's what i did with my IEMs)
other brands to look out for: sony (good but super cheap), shure (their se215 IEMs are awesome for the swapable cable, but that's a earbud like thing not headphone), klipsch (yet again, earbud but higher quality).
i've been looking into the whole world of audiophile products for a few years now and i think these are things that people starting out for
GOOD headphones and not stuffty beats.
