Pioneer SE-M531 headset evaluation

Pioneer SE-M531 is a very popular headset? Why did you choose this headset evaluation? Is it poison in the SE-A1000? I am afraid there is really an impact in this regard. Unlike the Pioneer MJ series, the M531 and the A1000 are both avant-garde home audio and video and entertainment positioning. It is indeed not the main model of Pioneer in the personal user department. It is because of the good performance of the A1000 that we are interested in listening to the M531 performance of this exaggerated appearance. At present, the price of the National Bank M531 is 299 yuan, and the price of parallel goods is less than 200 yuan.

Pioneer SE-M531 is a strange shape. As a 300 yuan headset, because it is positioned with TV or living room audio and video entertainment equipment, it is not too small, and the headphone cable is also long enough to reach 3.5 meters. . Since the street and the portable are not considered, the thickness of the earphone casing is not small. What is more interesting is that there is a very obvious "hole" in the casing.

The opening on the outer casing talks about its use in the official data. The official translation of the "Powerful Bass Duct" "Stunning Bass Conduit" is also displayed next to the opening on the earmuffs. In short, it is a design for low frequency service. . In the official description, the M531 is positioned and closed. Indeed, except for this bass tube, it is indeed a closed-ended earphone. This catheter design is very interesting. In fact, in actual use, even if you put your finger in to block it, it will not change the sound of the headphones. That is to say, this duct is not a device for exchanging air with the outside air, and is a device for adjusting the airflow between the earphone casing and the internal cavity, which is very special.

The Pioneer M531 earphone uses a 40mm diameter neodymium magnet magnetic speaker unit, using the CCAW voice coil [Official Information]. With its large enough earmuffs and ear pads, the size of the all-inclusive ear can be achieved. There is a thin sponge on the front side of the earphone unit, but this part of the sponge is not well glued with glue, which will damage the delicate image of the product. That is, the plastic part of the head frame, the plastic quality of the rotatable joint part is not so high-grade. However, the process of the glossy plastic of the earphone casing is still very high, especially in the photo. Although the size of the earphone is large, but the weight is light, the pressure of the head frame is also slightly looser, and the wearing comfort is good.

We used the Monitor 06 MX, HiFiMAN HM-901, and vivo Xplay3s as the main test source for the headset. For the sake of its audio and video application positioning, we also used it with the TV, and the test track was also biased. The contrasting headphones are mainly the Rambler H840, the Pioneer SE-A1000 and the innovative Aurvana Live! 2 as a reference.

Overall impression : The Piston SE-M531's two bass devices are enough to attract eyeballs and even cause psychological cues - its low frequency is fierce? Maybe the psychological expectation is too high. The first time I heard M531, I don't think it has too much low frequency, even more than Live! 2 is less, the low frequency ratio is not large, the overall sound style is relatively neutral, and the sound is relatively balanced. It is definitely not a low-frequency headset. Not even a low-frequency heavy-duty headset.

High-frequency performance: M531's high frequency is more neutral and restrained. Compared with H840, the whole sound is more relaxed and stretched. The medium-high frequency density is better, but the resolution is slightly worse, and the extremely high frequency part is slightly harder. The level of sound and the width of the sound field are obviously not as good as the H840, and certainly not as Live! 2, there is A1000. In the big dynamic performance, if you match the sound source of 06 MX or HM-901 level, the medium and high frequency is better and the sound is more explosive. In some strings, the performance is also neutral and restrained. The details are not enough, but they are not obviously blunt, and there is no obvious sense of decoration.

IF performance: M531's mid-range thickness is significantly better than H840, vocal performance is very loose, stretch, compared with high-end headphones, its IF resolution is not good enough, but the dynamic and image is impressive. With H840, Live! Compared with the 2 level headphones, its medium frequency is more calm, and it is very open when the dynamic is dynamic. It has better performance under the amp. The performance of the vocals is also fuller, and the male voice is more solid and emotional. The only shortcoming is that the medium and high frequencies are slightly rough when the dynamics are large.

Low-frequency performance: The two low-frequency holes of the M531 do not mean that it is an earphone that stands out at low frequencies. For example, it does not have the low-frequency modification of Beats or even B&W P5 headphones. Its low frequency is still relatively neutral in overall sound performance. However, the design of the special structure seems to make the M531 helpful for its low-frequency dive details. In some low-frequency, deep-deep audition songs, the M531 can respond quickly, which is relatively rare in any earphone. And its low frequency also maintains a relatively relaxed style, in the performance of film music, film special effects, etc., in fact, can not be particularly exaggerated [may not be as good as Live! 2, the ultimate HFI-780], but also better than the H840 headphones low-frequency sense, dynamic better, the thickness of the low-frequency is also significantly better.

to sum up

For a 200-odd headphone, you may not match it with a particularly good sound source or even an amp. The sound performance of the Pioneer M531 is equally acceptable when paired with a level sound source such as Xplay3s. The low-frequency dive and intermediate-frequency thickness advantages can still be Show it out. In terms of low frequency, the M531 is specially designed to match some of the sound sources with better driving power. At this time, the low frequency deep dive and the big dynamic advantage will be better. Considering the audio-visual entertainment headphones, it is more suitable for low-frequency and medium-frequency neutrality, at least in terms of vocal performance is not as light as AKG or H840. Compared with the H840, the overall hearing of the M531 is more resistant, and the quality of the mid-high frequency is slightly worse, but the intermediate frequency and low frequency parts have obvious advantages.
