I always wanted to try "open back" headphones, and these happened to be the cheapest that had decent specs. While it may not sound like my friends pair of Beyerdynamic DT990, it does provide very good sound! The frequency response is clean and flat, it doesn't boost anything, I can hear everything from the bass drum to the high-hat with these headphones. The stereo separation is phenomenal, I can hear things pan right to left like never before, it sounds more complete and dynamic now. These headphones cost me less than $20! And even came with a 1/4th inch stereo adapter. The impedance (32 Ohms) and the fact that it's open-back makes it a bit of a double edge sword. On the one hand, the high impedance helps block out whatever distortion is coming out of the headphone jack, and the open-back nature adds more depth to the sound stage, on the other hand, BOTH of these factors means that the headphones will be quieter and thus the volume has to be raised accordingly. That can be problematic when you try using this on a low output device, like a phone or computer. If need be, I can use a headphone amp. One last thing to mention about the open backs of these headphones, sound leaks. You can hear the outside world, and conversely the rest of the would can hear what you're listing to, so these are pretty far from "noise cancelling", These are all things to consider. I love these headphone! And maybe you will too!
