On February 28, 2020, Freeman Dyson drove west at the age of 96, leaving behind an unfinished vision of the universe.And there is a earphone and headphone brand called "SONGX" that condenses the "daring" vision of Dyson Ball into a pair of true wireless headphones.This headset is shaped like a Dyson ball to pay tribute to Freeman Dyson.The metal structure on the outside of the headphone symbolizes the solar panel surrounding the sun.At this moment, what you are holding in your hand may be a hot star.Hold the tws earbuds bluetooth heaphone in your hand and push it away. It turns like an asteroid or a star, and the universe is in your hand.In particular, the outer ring of metal material has a delicate and shiny touch, which also renders the future cold science fiction sense.In my heart, it has a solar system gap from other headphones in terms of appearance.Not only is the appearance outstanding, the performance of this headset is also hard-core:Using 6mm Hi-Fi level high-performance speakers, the sound quality is good enough;The earplugs plug the ears and have a certain passive noise reduction effect;Both ears are the main earphones, either side can be used alone;Wireless charging, long battery life, IPX5 waterproof;Bluetooth 5.0 low energy, stable connection performance.

HIFIMAN TWS800 is a true wireless headset with a built-in independent amp and an impedance of up to 150 ohms. Seeing the previous paragraph, does it feel very long? I think it is necessary to write it out, because whether it is in the real wireless field or in the wired HiFi audio field, there are still very few brands that can achieve mass production of 150 ohm earphones.It is not easy to match high-impedance headphones.Due to the uneven front-end equipment, it is difficult for general consumers to match high-impedance headphones. For example, some consumers use mobile phones to push directly. Such equipment often fails to achieve the required slew, resulting in insufficient sound pressure. In addition, Headphones will have the largest impedance in the low frequency part (the headphone impedance is not static, it is a dynamic variable, and the impedance is different at different frequencies). If the power is not enough, the low frequency will be weak. Although high-impedance headphones are easier to push better than low-impedance headphones, in fact, portable devices that want to drive high-impedance headphones better require portable amps and other equipment.WS800, a true wireless headset, personally feels that it provides a complete set of sound-like solutions for general consumers: you don’t need to consider whether the sound pressure of the front-end equipment is sufficient, you don’t need to consider sensitivity, and you don’t need to consider collocation. And so on, just choose the music you like through the sound source and enjoy it directly after wearing it.Sound quality:This headset has a strong impulse to share the sense of hearing from the beginning, no matter from which dimension of the sound, quality or sense of hearing, I want to write too much.Summarize the sound in one sentence: the low-frequency cohesion is strong, and the dive is deep; the mid-frequency vocal density is medium, which continues the gentle tuning style of HIFIMAN; the high-frequency is smooth and the degree of restoration is acceptable. In addition, the sound field is generous, instrumental music and vocal images are slightly behind, with a sense of hall. In addition, the overall sound style is suitable for both HiFi enthusiasts and mass consumers.The TWS800 headset. A major feature of this headset is that it is equipped with an independent amp structure and uses a 150 ohm high-impedance unit. Compared with other true wireless headsets, it is flexible, cohesive, and diving. It is "one ear lift." In "Drum Poetry", which can well "monitor" low frequency quality, the low frequency of TWS800 is best described as "fight to the flesh". The drums are clear, the tension is acceptable, and the transients are well matched. And dynamics, so that it has a certain sense of speed, and it will feel that the drums rebound fast. In addition, the cohesive performance of the drum sound is more prominent, which is mainly reflected in the sense of "strength", that is, the cohesive force accumulated by the drum head, the depth of diving, and the good dynamic performance, which can satisfy some pursuits of low-frequency texture. Enthusiasts request.The vocal part still continues the HIFIMAN style. The brand's in-ear products, especially the performance of the vocal style, will basically not change much, as always, it is warm, delicate and has a certain sense of agility. I personally think that the vocal part of TWS800 has some RE2000 flagship flavor, and lacks a sense of charm. The sound bottom is still a warm sound system. After changing to the official two-section set, the transparency of the mid-frequency part is still good. In terms of quality, TWS800 basically continues the sound density of RE2000, and does not feel too dense or thin. In short, it is just right.TWS800 continues to use the topological diaphragm, so that the high frequency can reach 30KHz, and the overall tone is also significantly changed.After TWS800 is worn, it can feel very close to the ear and very comfortable. This is because the inner side of the earphone cavity uses a skin-like coating material, and the cavity is developed after the use of RE1000 to customize the user's ear canal size and collect big data. , Improve the overall wearing comfort.In terms of battery life, used it for no more than 1 hour except for the burn-in time, and then put it in the charging bay. During the week of the business trip, the charging bay has electricity from start to finish. The official claims that the headset battery life can reach 4.5 hours, and the use of the charging bay can reach 31.5 hours, which can fully meet the needs of one week of use, of course, it depends on personal wearing habits.

Apple AirPodspro use function and operation method1. Take out AirPods Pro in the correct wayThe appearance of AirPods Pro is not right-angled like AirPods. In order to facilitate the user to remove it with one hand, Apple has a special design at the storage angle. People who don’t know may find it difficult to take it out. In fact, only a small trick is needed, finger on the back of the headset. Push it to rotate it out instead of using two fingers2. Enable noise reduction function to get better sound qualityBy default, press and hold the lower part of AirPod Pro to switch between noise reduction and transparency modes, or through iPhone or iPad, open the control center and press and hold the volume Bar, and you will see the noise reduction mode below3. Click to view wireless charging statusAirPods Procomes with a wireless charging box, which can be used with Qi wireless charging charging pads. There is an indicator light on the outside of the charging box. It will light up for a few seconds and then turn off when charging. To check the charging status, just tap it with your finger and the indicator light will light up again. Orange means it is still charging, and green means Is full4. Only turn on the noise reduction function for one earAirPods Pro also supports single-ear noise reduction, which is very practical for users who only need to use a single ear to make calls. Go to the AirPods in the settings, you can find the option to turn on one ear of AirPods noise reduction5. Control noise reduction through Apple WatchIn addition to iPhone, Apple Watch can actually control the noise reduction function of AirPods Pro, which is less known. First, make sure that you are currently playing music. After raising your hand to wake up the Apple Watch screen, click the icon with a triangle and three circles in the lower left to enter the AirPods Pro in the list.
