If you are making a choice between closed back headphones, consider this comparison of Audio-Technica ATH-M50x vs Sennheiser HD 25. The first device is over-ear and the second one is on-ear. Both of them are wired.
Features
We'll start with impedance which is 38 Ohm in the case with Audio-Technica ATH-M50x. Sennheiser HD 25 has a much higher level — 70 Ohm. Their sensitivity is quite different as well. Audio-Technica ATH-M50x has 99 dB, while the other appliance is 120 dB sensitive.
Let's get to frequency response. The headphones by Audio-Technica work in the range from 15 Hz to 28 kHz which is a great performance since Sennheiser HD 25 provides the sound with frequency response 16 Hz - 22 kHz.
Sound
Using Audio-Technica ATH-M50x I hear a powerful bass. Its sound is clear, detailed, and accurate.
The bass that you hear with Sennheiser HD 25 is just right without being exaggerated and the treble is so spectacularly clear. Mids and highs are crisp. Instruments are well layered within the sound stage and have good spatial cues.
Comfort and design
The most significant difference is in the weight of the headphones. Sennheiser HD 25 is exceptionally light as it has only 140 g. Comparatively, Audio-Technica ATH-M50x weighs 285 g. But the benefit of the second device is that the headphones are foldable and a carry case comes with them. The appliance made by Sennheiser does not have such advantages. Both of them have an adjustable headband.
Speaking of design, the fake leather on the headband and ear pads of Audio-Technica ATH-M50x look a bit cheap.
