While we appreciate the Sennheiser HD 25-1 II quality, we particularly appreciate its great design as a working headset for DJs and monitoring needs. This means that every focus has been placed on making the headphones last as long as possible without malfunctioning, and after more than 20 years of development, the headphones are still one of the most robust products on the market. The clear design of the headphones is also evident in the precision and choice of materials used. The headband, for example, retains its sturdiness thanks to smooth hinges. Also, the headband can be adjusted so that it can be worn securely. A matt granulate of very nice quality is also used, which does not affect the device’s prestige. The plastic of the headband is soundproof and wear-resistant. The finish is also designed to maintain the sophistication of the headphones. The headband and earrings also have an imitation leather pattern that adds a classy touch. The designers also padded both parts of the headphones to give a better impression to the wearer in spite of their long lifespan.

We appreciate the slim, classy design of Sennheiser headphones, and the HD 25-1 II is no exception, providing music professionals with a classy device with a lovely finish. The device’s vintage character increases its appeal, and many experienced audiophiles will be attracted to its simple and unobtrusive style. I also believe that everything has been planned in advance and that you can feel comfortable working on site. In addition, the headband has two straps and can be easily extended to fit your head. The earcups do exert pressure on the ears to isolate the outside noise. The only drawback is that you will feel little pressure on your ears after a few hours of use. However, that’s okay, and this level of padding ensures that you won’t feel it too much.

The lightness of the headband is to be appreciated because you can barely feel it. It’s also worth mentioning that the headphones are designed to suppress as much noise as possible from the outside. As a result, some users, especially those who wear glasses, may be concerned that the side clip may be securely attached to their ears. However, with a little practice, you’ll soon get used to this feeling.

Comparison

The Audio Technica ATH-M50x headphones are over-ear, completely wrapping around the ears, while the HD 25-1 II sports an on-ear type of design. Besides this difference, the ATH-M50X headphones are also foldable, which is not the case with Sennheiser headphones. Another difference is the headphones’ weight, the latter weighing 140 grams and the ATH-M50X 285 grams. This difference is significant and important, especially when you’re a DJ and need to perform your job for a long time.

The only negative aspect of pleasant is the memory of the pressure effect. In fact, you may feel some discomfort after about 4 hours of use; after a 15-minute break, this feeling will disappear. We would prefer that the earphones not feel this pressure. However, this is the only way to isolate them from outside noise. However, the designers wanted to reduce this tension by covering the earrings with a thick, flexible foam. The foam is also protected by a leather product and can be removed if necessary. So you won’t have to put up with it for long, and although you may feel a slight sensation, you’ll appreciate the passive isolation of these earphones, as you only need to push them for a few minutes to regain your comfort. And if you get used to using public transportation, you won’t bother your neighbors.

We also like to use the earphones because they’re easy to use and fit after a few hours of use. Even though the earphones do not have a noise attenuation system, they are very effective at applying pressure and blocking out background noise. These earphones are barely noticeable above your head, having a weight of 140 grams, and once you put them on, you won’t feel them anymore.

As dedicated DJ headphones, the HD-25 can be used for mastering, mixing, and recording. These headphones have a high dynamic range, so there is no need to use them at high volume levels. You will also notice the headphones’ level, which is useful for DJs and radio commentators because they can hear the results of the mixing console with one ear and the headphones with the other. The HD 25-1 II has a 120dB function of a 35mm motorized driver with SPL sensitivity. This way, you can efficiently mix several songs at once.

It’s a sound quality that appeals to many audiophiles because these headphones have a detailed and accurate sound with a very balanced response. At this level, the attack speed and impact are blameless, no matter what melody you play. However, the earphones have a 70 Ohms resistor and must be used with a proper power supply.

Note that these headphones allow for artificial sound reproduction. Therefore, playing any melody will sound empty at first, especially if you are used to the fact that the range of low and medium frequencies is increased by other headphones. With the Sennheiser HD 25-1 II, you first have to get used to the nearly dead sound, you don’t need to resort to tricks, and the sound reproduction is more accurate.

A nice level of detail is noticeable across the entire frequency spectrum without losing high-frequency detail. The sound imaging is also very nice, and I found it easy to distinguish and locate instruments in complex tracks. The headphone works best in combination with rock, metal, and acoustic. However, the sound of the bass was less clear when the genre was bass.

You can say that the headphones provide 120dB in terms of performance, which is enough to reach very high volumes. You will soon find that you don’t need to turn the volume up to maximum to use the headphones. And even though you turn the volume up, there is no distortion because they maintain the same accuracy level.

Comparison

Both studio headphones sound incredibly rich and detailed. We also appreciate that the ATH-M50x has a 28,000 Hz higher and clearer high-frequency range. Simultaneously, the 15 Hz bass range produced a stronger and more intriguing bass level (in contrast to 16 Hz in HD 25). We also found a significant difference in sound pressure levels, with Sennheiser headphones at 120 dB/mW and ATH-M50x at 99 dB/mW. At this sound pressure level, the Sennheiser HD 25-1 II generally sounded louder.

The impedance of the two headphones is completely different. The ATH-M50X has an impedance of 38 Ohms, whereas the HD 25-1 II has an impedance of 70 Ohms.
