As I have used the likes of various monitoring headphones, these give up a response that I can tell has been amped up to make it sound better giving you a biased source for mixing tracks.
I needed some headphones for some reason, and these were the only ones available at my price point at the local big box store. Sonically, they're not marvelous. I was a bit annoyed by the bass boost; this trend has been fashionable since the Beats by Dre phenomenon, and I'm not a fan. I should've just bought some headphones with a flat frequency response. Oh well. Luckily these aren't terribly uncomfortable. They have a detachable cable, too. I initially saw this is a disadvantage, but now I can see how this allows me to switch from 1/8-1/8 cables to 1/8-1.4 cables. This comes in handy when monitoring music from my Tascam or sampler.
Overall, these are nothing serious.
These have been my favorite headphones for countless years and I use them for almost everything. They are great for everything except for producing music sadly because these headphones exaggerate the bass sounds too much for making music but that's exactly the kind of thing that's makes them great for listening to music. The Bluetooth is a huge bonus for when you are listening to music while in the car or are studying at the library so that you don't have to deal with having to tuck the cord away in a pocket when going on a stroll when you are not using them.
These were the bomb before beats came out and Bose started coming out with more technological headphones. They block outside noise so well, but some of the lighter background instruments can get lost.
