Features

Audio-Technica ATH-M40x has 35 Ohm of impedance and this is twice lower than Sennheiser HD 25 has — 70 Ohm. There is also a big difference between their sensitivity levels. The first appliance is 98 dB sensitive and the second one has 120 dB.

Now, let's compare their frequency response. The headphones made by Audio-Technica provide a sound in the range from 15 Hz to 24 kHz, while you have a frequency response between 16 Hz and 22 kHz with the device by Sennheiser.

Sound

Although these headphones do not block noise as well as an active noise-cancellation function, they do effectively block out the surrounding environment.

The bass that is boomy to the point of being annoying on other headphones is not a problem on the ATH-M40x. The mids here are clear and accurate, with amazing low-mid depth.

The signature of Sennheiser HD 25 vs Audio-Technica ATH-M40x has a strong overall bass response, with the particular energy in the mid and upper bass that is impressive. The highs are astonishingly crisps and clean.

Comfort and design

The fact that Sennheiser HD 25 is foldable makes these headphones more comfortable. Moreover, this device is also much lighter as its weight is only 140 g, whilst Audio-Technica ATH-M40x weighs 240 g. However, it is no wonder, as almost everything in the first device is made of plastic. Whereas, the headband padding and ear cups of Sennheiser HD 25 are both made from the hard-wearing faux leather.

You can adjust the headband size using any of these appliances. Consider, that there is no carry case whatever headphones you buy.
