The sound quality of headphones is dependent on many factors. While nothing beats testing out headphones yourself, these specs help provide some clarity.


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 Sennheiser PX 200-II falls near the average for impedance and would not require an amp for best listening.
Frequency Response

The frequency response indicates the range of pitches the headphones can produce. For context, humans can hear between 20 Hz – 20kHz, but most songs stick to the middle of that range. 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.

Magnet Material

The magnet in these headphone speakers are made of neodymium, a very strong permanent magnet used in the majority of headphones.

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. Keep this in mind when evaluating the slightly lighter than average Sennheiser PX 200-II.

3.5mm is the most common input for headphones and is what you see connecting with MP3 players, smartphones, and laptops
