Since the major mobile phone brands removed the 3.5mm audio interface, everyone has gradually formed the habit of using wireless headphones. At the end of last year, I also started to work on the charger, and suddenly discovered that our living habits are not all changed by ourselves, and sometimes changed by the environment. There is no way. Faced with the powerful Fortune 500, it is difficult for individuals to contend and can only bear it silently. The old removable battery and expandable memory card designs have gradually disappeared. At the beginning, everyone was not used to it, but in the end they slowly accepted it.
The simplification of the 3.5mm audio interface is a loss for the user. The originally carefully selected wired headset can only be used by the adapter, and it also occupies the charging interface. But for wireless headset manufacturers, it is indeed an opportunity. The headset I share with you today is the C20 Active Noise Cancelling Head-mounted bluetooth headset, from UnionSta, founded in 2009, and has three sub-brands: UnionStar free, HAKUNA WASIWASI and GETELO. UnionStar C20 belongs to the HAKUNA WASIWASI series.
The headset packaging is orange, which is also the main color of the brand. The front is marked with the appearance of the headset, product model and product features, and the bottom left corner is the product LOGO of Little Wild Boar.
The back of the package is the product parameters, multi-language logo, model is C20, 18dB noise reduction, bluetooth 5.0, bluetooth specification A2DPV1.3, AVRCPV1.6, HFPV1.7, HIDV1.1, HVCTPV1.4, HVDV1.3 AND SPPV1. 2. The communication distance is 10 meters, with a built-in 450 mAh battery, the battery life is about 10 hours when the noise reduction is on at 70%, and the battery life is about 12 hours when the noise reduction is off at 70%, and it takes about 3 hours to fully charge the battery.
The product comes in double packaging. After removing the orange outer packaging, it is a black inner packaging. After opening, you can see that the headset is fixed in a black hard sponge, protected by an environmentally friendly plastic bag, and other accessories are stored in a small orange box.
After opening the inner packaging, it was found that it was a quick start manual, the steps to use the headset to turn on, and the button functions were introduced.
Headset (both earmuffs are also protected by environmentally friendly plastic bags), storage bag, manual, 3.5mm audio cable, charging cable. It can be seen that UnionStar C20 is a wired and wireless dual-mode headset.
The headset storage bag has a texture and feel like calfskin material. The texture is very soft and waterproof. After the headphones are folded, they can be put in the bag. When traveling or traveling, putting a suitcase or backpack is also a kind of protection for the headphones.
UnionStar C20 uses a single-layer head beam design, which is also a conventional design for outgoing headphones. Compared with the double-layer head beam, the appearance is more concise and easier to store. When not in use, you can hang it around your neck, or carry it in your hand or put it in your backpack.
The headset adopts a double-folding design, and both earmuffs can be folded and stored at a large angle to achieve the smallest volume, and it will not take up too much space when put into a backpack or suitcase. In fact, it would be better if it was designed to rotate at 90°, so that it can be put in a briefcase or computer bag.
In addition to the silver decoration on the outside of the earmuffs, the headphones are all black with a neutral design. In fact, the UnionStar C20 also has a military green color, which is more suitable for young people to wear. The external treatment of the earmuffs is relatively delicate and has a skin-like feel. I tried it, it’s easy to stick fingerprints.
The ear part of the headset is made of leather material, the texture is very soft, and the inside is a sound-absorbing sponge for stronger sound insulation. The headset uses a 40mm sound unit to enhance the bass.
Each switch is designed on the left headphone, ON/OFF is the ANC active noise reduction switch, to the right is volume-(short press)/previous song (long press), then volume + (short press)/next song (long press) ), the last is the multi-function button, long press to turn on/off/reject the call, short press to pause/play/answer/hang up/cancel dialing, double-click to return the previous call.
The lower part of the headset, on the left side is the indicator light. The blue light is on when the headset is turned on, the red light is on when charging, the red and blue flashes when the bluetooth pairing connection is connected, and the green light is on after the noise reduction switch is turned on. In the middle is the 3.5mm audio interface, which can connect to mobile phones, tablets, and computers in wired mode. On the right is the Micro-USB charging interface. It would be better if the Type-C interface is used, which is more convenient and more durable.
UnionStar C20 adopts a single-layer head beam design. The inner side of the head beam is padded with memory foam. The outside of the foam is made of silicone, which is soft to the touch.
The two sides of the head beam can be stretched up to about 20mm, and there is a sense of scale when stretched, and it can only feel a little astringent. When it is stretched, it can be seen that the inside of the head beam is reinforced with steel bars, which are embedded in black plastic and will not cut hands.
The inner side of the head beam is marked with a white “L” and “R” to distinguish the left and right.
The headset weighs about 240g, which is a mid-level weight among similar products. It is slightly heavier than some clip-on small earmuff headsets of about 190g, and lighter than some large earmuff gaming headsets of about 300g.
After actual measurement, the long diameter of the earmuff is about 100mm long, and the short diameter is about 80mm long, which can basically wrap the adult’s ears. The full-enclosed design, strengthen the internal sound-absorbing sponge, can enhance the sound insulation effect of the headset.
My head is relatively large and sharp. After stretching the head beam by about 70%, the top of the head beam just touches the top of the head. The weight of 240g is not strong. If the head beam is shortened and the top is close to the top of the head, it will feel a little bit of pressure at this time. At the same time, I also wear glasses all year round, and the softness of the earmuffs is good, and there is no discomfort when wearing them.
From this angle, it can be seen that the headphones completely wrap the ears, and there is no feeling of pinching the ears when wearing them. In short, you should adjust a length that suits you according to your head shape, but the extension of the headphone beam is not marked with a scale, and you have to adjust it next time you use it. It is recommended that the manufacturer add it in the later version.
Let’s actually experience the sound quality effect of the headset, and the mobile phone is Huawei Mate30Pro. Long press the headset power button to turn on, turn on the bluetooth function of the mobile phone, then you can see the UnionStar C20 device, click to pair and connect. The next time you use it, as long as the headset is turned on, it will automatically connect. I set the headphone volume to about 70%, and listened to music such as “Crying Sand” and “Drum Poem”. The vocal part gave me a personal feeling that the sound was sweeter. The clarity of the cappella at the beginning of “Cry Sand” was still Yes, it can clearly distinguish the singer’s breathing sound. In the “Drum Poem” part, the bass is enhanced, and there is still a sense of shock. Then, I tried the voice call again. The call was still very clear, and the effect was much better than the earpiece. The earmuffs are indeed very soundproof, and I did not turn on noise reduction during the call. At the same time, communicate with the other party to see how the headset microphone is effective, the other party’s feedback, the microphone clarity is okay, and there is no obvious noise.
Then I experienced the newly launched “Call of Duty”, the positioning effect of the headset is still possible, the direction of gunfire, and the distance of the enemy’s footsteps are still accurate. In addition, compared with wired headphones, the right-hand operation is completely released, and the middle finger and ring finger no longer need to clamp the headset cable connector.
Of course, compared to the wired mode, the power consumption of the mobile phone itself is still higher when connected via bluetooth. However, the power consumption of the headset itself is okay. After playing for a few hours, the power consumption of the headset is not large. The bass of the headset is strengthened, which makes the game’s battlefield effect stronger, which is much better than that of the loudspeaker.
Active noise reduction headphones, it is natural to test a noise reduction effect. I tested it at night. The environment was relatively quiet at night, and the noise was only about 37dB. When the range hood was turned on to the maximum level, the test noise was close to 70dB, which was quite noisy. In general, when cooking, I set the sound of the mobile phone to the maximum so that I can barely hear the broadcast. In fact, the sound insulation effect of the earmuff itself is quite strong. When the noise reduction is not turned on, you can listen to the broadcast and watch the video at a normal volume of 70%. After turning on the noise reduction, the sound feels closer to the ear, and the ambient sound is reduced to a certain extent. The effect is not so obvious, I don’t know if it is caused by the sound insulation effect of the earmuffs itself. For outgoing headphones, active noise reduction is still quite needed. In order to pay attention to the surrounding environment and turn off noise reduction when walking, while taking a bus, subway or in a noisy crowd, you need to turn on noise reduction to improve listening experience.
