BONNAIRE is said to be a headset brand from Hong Kong. The MX-330 in-ear headphones is priced at RMB 399. It is made of transparent plastic case and double-acting speaker. Available in blue, black and red.
The BONNAIRE MX-330 not only uses a transparent case, but also uses a changeable line design and supports iOS's remote control function. The interchangeable cable socket and plug of the earphone are more interesting and look like many bayonet ports used for power supply. This interface is actually very plugged and unplugged. As a headphone changeover design interface, there is no problem in reliability. The transparent cover of the earphone is generally in the process, but the MX-330 cleverly puts the glue side on the inside of the earphone [on the side of the catheter, when worn On the inside side], so the overall look is beautifully assembled.
There is no doubt that the double moving ring is the biggest selling point of the MX-330 earphone for the earphone enthusiasts. Compared with the multi-unit ring iron and moving iron earphone, the multi-moving ring solution is more intriguing because it can not be theoretically found. The technical advantage of multiple moving coil units in one earphone. We have never heard of a multi-unit dynamic ring earphone with excellent design.
Since the MX-330 headphones use a transparent case, we can clearly see the placement position and wiring method of the speaker unit inside [maybe the photo is not clear enough, but the naked eye is very clear]. We see that the MX-330 is different from two. The dynamic speaker is composed. From the back, the magnets of the two speakers are large and small, and the difference is obvious. The magnet of a speaker that is facing the outlet of the in-ear extension is larger, and the speaker looks like this on the back. The size is also larger. And next to it, there is a headphone outlet at the outlet of the earphone. It has a much smaller magnetic steel, but the size of the speaker diaphragm or the front exit is not much smaller. But this part Since the glue placed on the speaker affects the visibility of the transparent casing, it cannot be accurately judged.
From the connection point of view, the MX-330 two speakers do not do a simple crossover process, but directly connect the parallels. The way of wiring can be clearly seen from the transparent case. In the case where the capacitor is not used at all. Next, then the two speakers are either parallel "double push", or some rough crossover by physical occlusion. Since the output power of the headphone speaker is very small, such physical occlusion is definitely effective. But for caliber Already a big dynamic speaker, it is definitely not a good idea.
Since the MX-330 is intended to be divided by the occlusion method [the side speaker opening is far away from the duct exit], there is another problem. The front of the speaker unit is blocked, how does the diaphragm vibrate backwards? There is no way to deal with it. That is to say, the entire single cavity of the rear side of the moving ring speaker of the MX-330 may be completely enclosed, which is more common in the micro moving coil. For example, the double moving coil earphone made every day is like this. Monomer. What does this mean? This means that if it is a closed structure, the shape of the outer casing of the earphone will have almost no effect on the sound, that is, the air in the entire space of the earphone casing cannot be used. In short, it is a very different kind of design. We speculate that the MX-330 may be a similar design. Of course, if the speaker unit is not closed, the control of the double moving coil may be more difficult, and the mutual interference is much more troublesome than the frequency division.
From the perspective of the overall acoustic structure, it is already very difficult for the MX-330 to do well.
The overall listening of the MX-330 is really bad, but if you really buy this headset, it is worth 100-200 hours. The improvement is still quite obvious. The sound performance of the MX-330 is extremely restrained, the intermediate frequency and the middle. The low frequency has obvious signs of very severe extrusion, and the dynamics of high frequency and medium frequency have extremely severe compression. Maybe when you listen to a very bright music of high frequency itself, you will feel that the sound of MX-330 is a bit crowded. But if you listen to an ordinary pop song, you may feel that the headphones are broken. Its high frequency is not only dark, but the dynamic is very small, and the female voice seems to be sung by the mouth. If this is a The speaker, the feeling is that the handle is held down by the speaker diaphragm to make it work. In short, the sound of the MX-330 is catastrophic, and there is still a long way to go from normal use.
