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.

The mix of metal and wood. The sound of nature!

The experience of SIVGA Planar Driver Earphones: Nightingale

Those who are acquainted with SIVGA might recognize their preference for naming their headphones models after various birds,symbols of freedom and beauty.For instance,the golden oriole,luan (a mythical bird like the phoenix),and phoenix models,each features elegant wooden shells that harmoniously complement their natural,captivating sounds. Despite the company's earlier earbuds release focusing on wooden components,they did not attribute a bird's name to any of the earlier earbuds.That is,until the introduction of their thousand-yuan "Nightingale" planar headphones.This oversight highlights SIVGA's importance in "Nightingale".

Nightingale, which is often seen in literary works, is actually the Xingjiang song finch. It is characterized by its excellent singing skills, and it likes to sing at night. As an middle-aged person, I can only settle down and enjoy the music when it is quiet at night, which is quite matching with this headphones. Next, I will share my recent feelings, and let's take a look at the specific performance of this "singing elf":

As the flagship in-ear headphone product under the SIGVA brand,the packaging of "Nightingale" is exceptionally exquisite.The entire box is shrouded in a profound darkness,with a captivating,bright gold plaque that contrasts beautifully with the deliberately highlighted Chinese name below. Although there is no line drawing on the cover, this white-space approach instead gives people reverie.

In addition to the headphones,the packaging box also includes a dedicated storage box for the included earplug sleeves.I counted four pairs of silicone earplugs (each pair in large,medium,and small sizes, additionally, another pair is on the earphones, totally four pairs). As for the cable,it’s a kind of Japanese square-shaped silver-plated copper wire,with a 4.4mm plug.Given the excellent quality itself,there's no need to purchase an additional balanced upgrade cable.

This storage bag is worth talking about. It is made of rhombic patterned nylon, with a durable,hard and thick shell. It can protect the headphones from damage when placed in the backpack and being squeezed. The space inside is also very large. In short, I really like it.

The headphones feature a detachable 0.78 dual-pin design,making it convenient for future upgrades and cable replacements.The black paint-coated wire matches the earplugs nicely,while the plug handle is also reinforced with a spring,reducing the likelihood of bending.

This is also a classic design of the headphone cable of SIVGA. The cable is composed of 4 strands of 7 0.23mm diameter wire cores + 250D bulletproof silk, with an imported high-gloss soft PVC material on the surface. The cable is flexible and will not be easily tangled during daily use.

Let's take a closer look at the "Nightingale". The waterdrop-shaped earphone cavity is elegant and atmospheric.The front shell is crafted from an aluminum-magnesium alloy,while the rear cavity panel is made of precious wood that has been carefully selected and processed.Although the surface appears smooth after meticulous processing,the wood grain left behind by time varies from piece to piece. As the saying goes,birds choose the right tree to perch on,and the adoption of real wood backplates and the naming of the headphones are truly complementary.

The bright silver metal earphone shell is paired with dark-tone solid wood veneers, and the contrast of the bright and dark color differences is elegant and of high grade. Decorated on the ears, it not only has a soft and pleasant sound, but also can be a decorative embellishment when going out. The combination of different materials also puts a high demand on the manufacturer's workmanship. In this regard, SIGVA is always the master. Not only is the material selection exquisite, but the workmanship details are also very solid (the weight of one earphone is about 15 grams), making the entire earphone exude a remarkable sense of high-end. It is also very comfortable to wear, and it fits naturally with the auricle, without accidentally falling off, and there is no discomfort even after one wearing it for a long time.

Let’s take a close-up of the specific part, and you can see its fine workmanship. The alloy part is processed by 5-axis CNC, and after polishing and grinding process, it emits a metallic luster. What’s more, the wooden shell panel is made through traditional handcrafts such as painting and natural air-drying, giving a round and smooth shiny feeling.

Metal mesh detail on the sound guide tube: The inner cavity of the earphone has L and R labeled indicators for the left and right ears.The "Nightingale" accurately controls the size of the sound outlet and breathability,reducing cavity resonance while extending the life of the unit and delivering a purer sound.

In terms of hardware configuration, Nightingale is equipped with SIVGA’s self-developed 14.5mm planar unit of ultra-thin composite materials, which consists of a dual magnetic field matrix structure composed of two sets of high-performance rare earth neodymium iron boron magnets, and is equipped with built-in aluminum wires. It has the advantages of high sensitivity, uniform sound field distribution, and good transient response. Compared with ordinary single magnets, the efficiency is significantly improved. In addition, its impedance is 16 Ohms, sensitivity is 100dB, and the frequency response range is between 20Hz-40KHz.

Finally, let's talk about the subjective listening experience. As a kind of planar headphones, "Nightingale" is not easy to drive. For mobile phones, it is best to pair it with a portable headphone amplifier (forget about the "small tail adaptor" with average driving power). After I got "Nightingale", I partnered it with Qianlongsheng's MUB1 “big tail adaptor” and XD05 BAL. And I continued to condition it for about 50 hours in a row, and the sound that was slightly tight when I first put it in my ears became more stretched and loose. In addition, it also has a better performance in details, dynamics, separation and sense of envelopment.

Its low-frequency response is moderate,but by no means deficient.The control over elasticity and density is impressive,with good clarity.Compared to the captivating and stunning sound that comes from instant gratification,the "Nightingale" offers a more straightforward approach.Although it doesn't contain excessive seasoning,it's not bland,either.Instead,it's refreshing and enjoyable,particularly due to its rich atmospheric presence,akin to the mist hovering over a mountain peak,providing a strong sense of presence and immersion.

The details of the intermediate frequency part are quite rich, and the layering is also very obvious, with outstanding resolution performance. Its sound is delicate and bright, the sound bottom is pure, the imaging is clear, and it has a certain cohesion, without a loose and thin feeling. The human voice is penetrative and the separation between each instrument is good. When listening to Cai Qin's "Forgotten Times", the low humming and singing at the beginning, and the belting out later, every subtle change and sound detail can be accurately grasped. The unaccompanied singing part has a mellow and vicissitudes of voice, with a relaxed and natural hint of sadness. When listening to the female voice, although it lacks a hint of sweetness and agility, it does not simply seek sensory stimulation, but tries to restore the original taste of the voice. The advantage is that it is real and peaceful, and full of charm.

The high-frequency response of the "Nightingale" is transparent,clean,and smooth,without any harshness.The linearity is clear,and the resolution and positioning are excellent.The details are rich,with ample information and good extension.Although the resolution is strong,it is relaxed and not dry or harsh. In terms of sound field,the horizontal and vertical distribution is reasonable and tidy,with a wide opening and a strong sense of immersion.Overall,the sound of the "Nightingale" is delicate and soft,smooth and silky.The vocal expression is sincere and warm.The connection between the three frequency bands is relatively balanced.

Summary: As a new in-ear flagship of SIVGA, "Nightingale" has a relatively high access threshold, which requires you to have a good front end on hand and be patient to condition it for a longer period of time. Its appearance has a unique texture under the shape of metal and wood and a high appearance level under the fine workmanship and beautiful shape, but in terms of sound, it is not the type that makes people amazing at first listening. It feels plain at first, but after a deeper appreciation, it becomes aware of the charm, the more you look, the more beautiful it is, and the more you listen to, the more pleasant it is. In short, it is a planar in-ear earbuds with distinctive features, and it is very suitable for one listening in calmness.

Sivga SO2 Wireless Earphones

In recent years, I've noticed a significant increase in the variety of headphones. Originally, there were merely wired and wireless options, while, nowadays, numerous wearing styles can be distinguished in headphones, ranging from over-the-ear, in-ear, semi-in-ear to bone-conduction types.

For the majority of us, owning multiple pairs of headphones for various needs is not only impractical but also expensive. Choosing just one type leaves us feeling unsatisfied and wanting more. The appearance of OWS headphones fortunately solve this dilemma. They provide a comfortable yet secure fit, impressive sound quality that's easy on the ears, and a more budget-friendly price, making them the optimal choice for most. Let's dive into the details and explore the SIVGA SO2 open-ear headphones.

Appearance

The SIVGA SO2 open-air headphones possess a clean and unadorned appearance, marking them as serious audio equipment. Inside the box, you'll discover a simple setup a charger case in the shape of a soap bar, a Type-C charging cable, and an instruction leaflet. The headphones come in either white or black, both of which are minimalist and stylish. I selected the white model for its more subdued tone.

Upon opening the charging case, today's protagonist comes into view. After several years of development, I must admit that the OWS headphones have reached an exceptional level of technological sophistication. The entire headset is incredibly compact, entirely unlike the bulky design of a few years ago. Moreover, the rapid advancement of craftmanship ensures a superior quality of hardware material with each side weighing only 10g.

Upon unfolding the headphones, examining the inner side reveals that the SIVGA SO2 headphones are non-in-ear designs. The speaker opening resembles a small speaker, with the charging magnetic connection point located above it. Added to this is a small indicator light on the side, ensuring that the entire headset has no redundant openings, providing excellent overall sealing.

Wearability Experience

One of the key factors contributing to the popularity of OWS headphones is their comfort. The ear hook of SIVGA SO2 is flexible, skin-friendly, and not easy to deform, so it is very comfortable to wear. At the same time, the shape of the earphone conforms to ergonomics. After wearing it, the sound-emitting port just faces the outside of the cochlea, neither entering the ear nor being too far away to affect the sound quality. The stability of the earpiece is truly durable. I tested it by vigorously shaking my head and found it to be incredibly stable. Even with vigorous exercise, it will not be thrown off. Coupled with its extremely light weight, it feels like nothing after being worn, which is very suitable for commuting or sports wear.

Sound Quality Experience

As a pair of headphones in daily scenarios, actually, I don't have such high requirements for sound quality, and I advocate that it's almost fine. The part of SIVGA SO2 that is responsible for sound uses a 14. 2mm PU + titanium diaphragm dynamic coil horn, which can ensure powerful low frequencies and delicate sound restoration. In actual listening, the sound field is sufficient, and it doesn't feel not enough because it is an open-ear headphone. The mid and high frequencies also perform better than expected, especially the human voice part, which is relatively forward. When listening to pop music, both male and female voices are well balanced. And in order to further increase the density of the low frequencies, SIVGA SO2 also adds a low-frequency sound effect algorithm, and the cohesion of the low frequencies is good, without the feeling of being too scattered.

No need to worry about sound leakage in daily use, the directional sound transmission technology ensures the direction of sound propagation, preventing it from leaking out and avoiding embarrassing situations. Moreover, the paired Bluetooth 5. 3 technology ensures a fast and stable connection, preventing unexpected disconnection and guaranteeing better sound quality.

Sport Experience

Based on the above introduction, it's evident that the SIVGA SO2 open-ear headphones are promising candidates for sports headphones, thanks to their exceptional stability. They can easily accommodate daily activities such as running, yoga, or working out. In addition, they offer IPX5 water resistance, ensuring that your headphones stay safe even when caught in light rain or during perspiration. However, it's essential to wipe them clean after use to prevent bacterial growth.

Daily Experience

SIVGA SO2 can definitely meet the daily music needs of most people in terms of sound quality, so the focus is on how convenient it is in daily operations.

Firstly, the headphone has excellent battery life. It is equipped with an 85mAh battery, which can be used for 10 hours when fully charged, and can achieve a super long battery life of 30 hours with the charging case. Normal commuting use basically requires charging once a week, with no power anxiety.

Secondly, through four microphones, combined with the ENC intelligent sound plus algorithm for noise reduction, high-definition calls can be well realized. In a noisy scene, it can automatically identify the human voice and filter out external noise, so that the other party can hear your voice clearly.

Finally, regarding operation, the SIVGA SO2 employs touch control, similar to most wireless headphones. In music mode, a double-tap on one side of the earphone can pause or play the music;volume adjustment and song navigation are controlled by left and right ear operations, with long press and short press differences. For those who have used wireless headphones before, the operation is intuitive.

Summary

SIVGA SO2 open-ear headphones are what I think are wireless headphones that can meet the daily needs of most people. They are healthy and comfortable to wear, with good sound quality, and are also fully equipped with call noise reduction and super long battery life. With the addition of sports attributes, they are basically perfectly configured. Friends who are still struggling to accommodate which type of imperfect headphones, might as well give OWS headphones a chance and give SIVGA SO2 a chance.
