The OWS sports headphones that truly achieves HiFi-level sound quality, SIVGA SO2 review.
The OWS headphones can also be HiFi.
Recently, the OWS true wireless headphones has become popular, but most of the sounds are blurred. It is somewhat difficult to find an OWS headphones with good sound quality. Just when I was suffering headache about this, fortunately, the HiFi headphones manufacturer SIVGA sounded the first shot of the OWS headphones with high-definition sound quality, and launched the SO2 with HiFi-level tuning quality. This OWS headphones has achieved the ability to outperform its competitors in the same price range in terms of connection stability, battery life, and sound quality performance. As an audiophile, how could Xiong Miao not buy it at the first time? After using it for a period of time, let's talk about how it is. To be honest, it really sounds good!
The SO2 is equipped with a 14.2mm oversized PU + titanium-coated diaphragm dynamic coil unit. After careful tuning by the manufacturer, the SO2 can achieve HiFi-level sound quality. Coupled with the open design and the use of directional sound conduction technology, the overall listening experience is very open and loose, just like listening to a small on-ear headphones. The openness of the entire sound range is very shocking, and it is also very clear, far exceeding the listening experience of some commercial-grade OWS headphones that are blurred.
What is an OWS true wireless headphones?
Briefly, it is an open design that does not require in-ear, nor does it require close fitting like a flat-head plug. It only needs to be hung on the ear, and with directional sound conduction technology, it can conduct music into your ear hole without leaking too much sound, which will not affect those around you. Because the sound conduction is directed to the ear, it is not easy to cause severe sound leakage. Whether you are taking the subway or working in the office, you can hear the music clearly and also hear the sounds around you clearly. You don't need to worry about not being able to hear the honking of surrounding vehicles when running outdoors.
Comfortable wearability and stable connection.
The SO2 weighs only 10 grams per side, comfortable to wear, the hanging ear component is soft and elastic, and has good supporting fits. It won't fall out when one running with it. The SO2 adopts 5.3 wireless technology, supports AAC high-definition audio protocol, and during Xiong Miao's use, the SO2 has no disconnection problem for several days, and the sound background is clean, without audible background noise, which is worthy of praise.
Strong battery life, ENC call noise reduction.
The SO2 supports 10 hours of earphones playing and totally 30 hours playing with the charging case as a power provider. With a total of 4 microphones on both sides, it supports ENC call noise reduction. When Xiong Miao talk to someone through SO2 during call outside, he has not heard the other person’s complaint about the sound clarity. For daily use, you don't need to carry the charging case with you when going out for the 10-hour battery life of earphones themselves can ensure enough power on the road. The SO2 supports turning on and off through touch. You can directly turn it off and put it in your pocket. If your commuting time is totally 3 hours in the morning and afternoon, the SO2 can be used for several days after a full charge.
Let's talk about sound quality.
I first listened to the jazz music "Dolce Nonna". You can feel that the SO2 can bring a very wide sound field space, and the instruments are separated from each other, and the sound details in the left and right directions of the sound field can be heard from far away. The listening experience is very loose. Compared with those consumer-grade OWS true wireless headphones, the sound field range of the SO2 is wider, and the sound clarity is also better. There is no fuzzy feeling. The distribution and detail analysis of the three-frequency density are very balanced and clear. If the vertical performance of the sound field is also strong, it would be perfect.
Then listening to the song "烟青步晚", you can intuitively feel that the SO2 does have HiFi-level sound quality performance. The sound outline in this song by Chinese guqin (an seven-string Chinese Zither) is very clear, the main body of the song shows a feeling of wide stretching, the density is full, the timbre is transparent, and the details of the air vibration generated by the guqin player plucking the strings are very clear. The overtone is rich, which is hard to hear on consumer-grade OWS true wireless headphones. The resolution is strong, and the timbre is also quite neutral, without strange coloration. "烟青步晚" sounds very natural.
"Special One"(A song sung by Eason Chan and AGA. ) is chosen to test the human voice performance. Compared with some consumer-grade OWS headphones, the human voice through SO2 is not so thin or blurred. Its human voice performance is clear and condensed, with full density. With emotion, the human voice is not straightforward, not rough, not cold and thin, with a little warmth, and it sounds more interesting and not bland.
The most amazing thing is that, although it is an open design, the human voice fits the ear as well, which will give you a more comfortable listening experience. In terms of human voice timbre, the inherent timbre of Eason Chan and AGA embraces relative restoration, just with a little more warmth to make the human voice sound more comfortable. It sounds more lyrical when listening to some other old love songs, and the clarity is also high.
In the analysis of human voices, the details of the breath and the tremor of the throat can be heard to a certain extent by SO2, not a fuzzy listening experience. The advantage is that you can hardly hear sibilance from beginning to end when listening to this song. If you are listening to songs with normal recording quality, you can hardly hears sibilance with SO2. With HiFi level, SO2 is really much better than that of consumer-grade OWS headphones concerning human voice tuning.
The low-frequency test is made by playing Wafia's "Pick Me". The low-frequency effect is what Xiong Miao wants to praise SO2 for. When listening to this song, the drum sound is solid and dense, with full impact, which belongs to the texture of hitting the flesh, very energetic, and the transient speed is very fast. The speed of the drum sound is easy to control, and the rhythm is not sloppy. By playing this song, SO2 reveals full rhythm and a strong atmosphere, with low-frequency overtones and good detail texture control.
Later, when listening to "Ferry", the low-frequency SO2 is very deep, full of details, and the open-ear desin causes no loosening and no blur and ensures the condensation of the low-frequency. The tuning details of the manufacturer are very sincere. It is worth starting with the OWS headphones with the true HiFi-level tuning.
To be honest, before listening by SO2, Xiong Miao had a resistive attitude towards this kind of OWS headphones, for Xiong Miao himself is an audiophile with the opinion that this kind of headphones may not sound good, it may leak sound seriously. While, Xiong Miao’s personal use proves the surprises of SO2. It is very satisfying in terms of connection stability and sound quality experience. The application of directional sound conduction technology allows Xiong Miao to listen to music in the office for an afternoon without a colleague telling Xiong Miao that the headphones is leaking sound and disturbing him. There is no need to worry about the discomfort of wearing in-ear headphones for too long. Xiong Miao just shouted that it sounds so good! In the future, I will be continuing to pay attention to the development of OWS headphones, and I hope there will be more OWS headphones from HiFi manufacturers.
