Taking a different approach -- A review of the Miole TH330 true wireless earphones

As a HIFI audio equipment enthusiast and a heavy user of TWS for iPhone, my requirements for true wireless headphones (hereinafter referred to as TWS) including AirPods and other products are relatively demanding compared to ordinary people. Of course, this multiple-choice question is actually not as difficult as it used to be. After all, most manufacturers that make accessories for smartphones are basically making TWS. The advantage is obvious, and the range of choices is quite large. The only downside is that it is easy to be dazzled. Originally, TWS has developed to this point, and it is reasonable to say that traditional HIFI manufacturers have nothing to do with it. With the size of this large number of peripheral accessory brands, supply chain and strong publicity and promotion advantages, any one of them is not comparable to the traditional manufacturers known by HIFI enthusiasts. Since the ordinary road is not easy to take, you have to change the way of playing. MiAolo is a typical manufacturer that has played this well.

The TH330 pair of tws headphones is the latest model of Miole. In fact, after careful consideration, I found that the gameplay of Miole is not complicated. As can be seen from the previous model TH220, the main highlight is the design. It completely adopts the appearance of professional public molds to customize the headphones, supplemented by exquisite and beautiful artwork panels, which is hard to resist for the general non-audiophile group. However, this process seems to be unable to be produced through the assembly line at present, so it is destined that this design of tws cannot become mainstream----isn't this what Miole hopes for... Of course, for HIFI brands, this design of tws cannot be said to be the only one of Miole, but when it comes to cost performance, no one can surpass it.

 

The whole resin cavity is one-piece injection molded, and the sound unit solution of two irons and one ring is commonplace by the standards of professional HIFI headphones, but by the standards of a TWS, this material is already very sufficient. After all, for TWS-type headphones, the inherent power supply bottleneck is there, and it is not easy to make these three units work. The entire cavity of TH330 is pure black, and the back is decorated with broken gold, which is calm and stylish. The feel of the charging storage box is similar to fabric, simple and simple, and exquisite craftsmanship. The official storage capacity of the charging box is 500mA. For the built-in battery of TWS, which is only a few dozen mA, it is enough to recover blood. In actual use, the headphones can be repeatedly charged three or four times and there is still room for it. If used for normal commuting, it is more than enough to last for a week. In addition, the battery compartment is also equipped with a charging indicator light and a remaining power indicator light. Even patients with obsessive-compulsive disorder can't find any problems with power management. Of course, the accessories are indeed environmentally friendly, with three pairs of silicone earmuffs of different sizes, a C-port power cable, and a cleaning cloth for wiping the cavity, and nothing else. Actually, it seems that there is nothing wrong with it. After all, a TWS is meant to facilitate users, and I really can't think of any accessories that are just needed but not provided by the manufacturer.

In fact, in the past, I would focus on the functional description of TWS-type headphones, and I would not go into too much detail on the sound. Because TWS is a device that sacrifices many aspects for convenience, in my opinion, as long as the sound meets the product positioning given to it by the manufacturer and has a breakthrough in functionality compared to similar competing products, it is a headset worth recommending. However, the product positioning of TH330 has been different from that of ordinary TWS from the beginning. Talking about its functionality can only be regarded as neither good nor bad at best. After all, TH330 has neither active noise reduction function nor wireless charging ability. From this point of view, there is really nothing worth talking about TH330. But what kind of people are the users of Miole, and what do they want? If you figure this out, you will know where this pair of TWS is good.

In terms of sound carving, TH330 generally continues the previous style, creating a popular foundation, and generally presents a balanced trend slightly biased towards the middle and lower range. No specific frequency band seems abrupt. In order to cater to the performance of the human voice, the imaging distance of the mid-frequency will be a little closer, but it is still a relatively restrained control. In most cases, it will not appear to be close to the face. Although it is not ruled out that there may be users who prefer this, from the manufacturer's tuning style, being conservative is the correct approach. The low frequency does not win by quality. As mentioned earlier, due to the inherent power supply level of tws, it is obviously unrealistic to make a low frequency as strong and rebounding as traditional wired headphones.

 

Therefore, it is appropriate to loosen up the low-frequency volume a little bit, to achieve as much cohesion as possible without excessive dispersion, so that it can provide enough atmosphere in most popular songs. This is also the consistent way that most TWS handles low frequencies, and TH330 is obviously more experienced in this degree. Compared with the low frequency with quality and quantity, the high frequency is obviously more difficult to adjust. From the actual performance, the ultra-high frequency of TH330 is obviously cut off. Although it is also a last resort, the remaining are almost all benefits. The direct reflection at the level of listening is the improvement of listening tolerance, and there is no stimulation that easily causes auditory fatigue. The completeness of the details of the mid-high frequency is still quite impressive. Even if it is used to listen to some physical instruments with a wide range of mid-high frequencies, there will be no obvious lack or sense of separation. Some electronic instruments with a wide range of high frequencies are also not difficult to control. The sound field is relatively regular, close to a normal circular sound field. Although the sense of boundary is obvious, it is not empty, and the energy density distribution is relatively uniform. In terms of detail revealing ability, TH330 is quite outstanding. Perhaps it is due to the support of two mid-to-high frequency dynamic iron units. The ability to analyze various sound elements is obviously at least half a level stronger than similar single dynamic coil solutions of competing products.

Regarding the adaptability of TH330, since it supports Qualcomm's APTX encoding, it can maximize its information advantage when adapting to some Android phones that also support this encoding. However, this does not mean that the device experience of the Apple camp is completely inferior. In fact, from the experience of using it with an iPhone for commuting for nearly a month, there was only one intermittent disconnection (not a device problem, but there was a strong interference source in the area, and AirPods were also disconnected), and the stability was excellent. In addition, TH330 can achieve IPX5 waterproof capability. Although this does not mean that it will be fine if it is left in the laundry and washed together, in the face of heavy rain in summer, such as forgetting to bring an umbrella, even if the underwear is soaked, TH330 may not have any problems. Of course, I am definitely not willing to do this kind of test, but I just understand it according to the objective concept of IPX5.

So in the final analysis, whether TH330 can be the only pair of tws for ordinary users, I think it depends on personal choice. In fact, in my personal opinion, if TH330 has ANC noise reduction function, even if its noise reduction level is not as good as AirPods Pro, I would be happy to replace my AirPods Pro with it. Because for the nature of my work, active noise reduction is a rigid demand, and it is still irreplaceable to a certain extent. However, this does not mean that the sound insulation of TH330 is not good. In fact, as a custom design of public molds, the passive sound insulation effect is still quite considerable. It has relatively good passive sound insulation, but lacks active noise reduction function, which inevitably makes people feel a little regretful. But I am still happy to carry it every day. As a person who separates work and life very well, I carry two mobile phones, so why not have such a lightweight tws.
