Obviously, the best test for sound quality is to listen to headphones first-hand. With that said, these specs can help add some context to your search.
Impedance and Sensitivity
Impedance and sensitivity can speak to the wattage needed to output certain volume levels. Low impedance and high sensitivity headphones require less power and are better suited for small output devices like smartphones or MP3 players. The V-Moda Crossfade M-100 falls near the average for impedance and would not require an amp for best listening.
A headphone’s frequency range represents the lowest and highest pitches that it can output.Considering that the human ear can only hear between 20 Hz – 20 kHz, the V-Moda Crossfade M-100 range of 5 Hz – 30 kHz is a little excessive.
Given the low bass frequencies and closed operating principle, this is a great set of headphones for bass heavy music such as dubstep or EDM.
Diaphragm diameter, or driver diameter, is another variable that affects the bass or treble output of the headphones. The V-Moda Crossfade M-100 diameter of 1.9 in is a bit higher than the average of 1.60 in for over-ear headphones making it slightly better for bass.
Weight is simply a user preference and metric of portability. It does not indicate higher quality headphones as some brands add unnecessary weight to their models. With that in mind, know that the V-Moda Crossfade M-100 is slightly heavier than the average over-ear headphone.
3.5mm is the most common input for headphones and is what you see connecting with MP3 players, smartphones, and laptops.
