The ability to PRODUCE bass is different from being "bassy" or "boomy".
HD280's are a studio headphone, calibrated and designed to give a FLAT response, meaning no crazy EQ curves. All frequencies are as close to equal amplitude as possible. HD280's have the frequency response and the sensitivity to accurately produce bass, whereas gaming headphones are designed to have "boom" or sound "bassy".
If you like accuracy and precision, studio headphones are amazing. If you like boom, gaming headphones are your choice. I use my studio headphones for gaming because I like REAL sound... not colored or "washed up" with bass frequencies.
