Monster Beats Pro Over-ear Headphone Review$449.95
As you can see from the graph we've so handily provided, the Beats didn't actually do too badly in terms of frequency response. What is worth noting, however, is the dramatically overemphasized bass and the erratic higher tones. While the Beats stay within our ideal dB range for a good stretch of frequencies, you may notice some weird volume boosts with sounds in the 2.5 to 5kHz range, and again in the 7 to 9kHz range. For those of you who aren't well-versed in kHz frequencies, the attack on a snare drum and sibilants like "s" and "sh" will seem louder than they normally should be. Or at least they may, if you can hear them over the bass.
The Monster Beats Pro have a relatively low level of distortion, but we've seen better from cheaper headphones, and certainly not this much from a pair of "studio" headphones. Audiophiles: prepare to upturn noses.
The Beats Pros were a little erratic in their tracking, but it's nothing that you'll probably notice in regular listening, as the shift in volume from each channel never really exceeded 3dB to either side.
