True Wireless Stereo (TWS) earphones are gaining popularity among people due to their practicality and ability to deliver good sound quality without cables. However, with so many options available in the market, choosing the right TWS can be a challenge. Here are some tips that can help you in choosing the best TWS according to your needs and preferences. Sound Quality Sound quality is the main factor to consider when choosing a TWS. Pay attention to technical specifications such as the drivers used, frequency range, and embedded audio technology. Larger drivers usually produce stronger sound and deeper bass. A wide frequency range allows the TWS to capture sound details better. In addition, some TWS are equipped with audio technologies such as aptX or AAC that can improve sound quality. Battery Life Battery life is another important aspect to consider. TWS with long battery life will be more practical and do not require frequent recharging. Also, check if the TWS is equipped with a fast charging feature. For example, some TWS can provide several hours of use with just 10-15 minutes of charging. Also, be sure to check the total battery life of the TWS and its charging case. Comfort and Design Comfort is something that should not be overlooked when choosing a TWS. Everyone has different ear shapes, so it is important to try different models and choose the most comfortable one. Some TWS come with ear tips in different sizes to ensure a perfect fit. Open-ear or semi-in-ear designs can be an option for those who want more comfort and do not want to completely cover their ears. The ergonomic and lightweight design can also increase comfort when used for long periods of time. Additional Features Additional features such as noise canceling, transparency mode, and touch controls can enhance the TWS experience. Active noise canceling (ANC) can help reduce external noise so you can focus more on your music or phone calls. Transparency mode allows you to hear the surrounding sound without having to remove the TWS, which is especially useful when walking or running on the road. Touch controls on TWS allow you to control music, calls, and volume without having to touch your phone. Water and Dust Resistance If you often use TWS while exercising or outdoors, choose a TWS that is water and dust resistant. TWS with IPX4 certification or higher can withstand sweat and splashes of water, making it more suitable for sports activities and outdoor use. Be sure to check the IP (Ingress Protection) rating of the TWS you choose to ensure its durability. Price and Quality Price is often a major consideration for many people. While there are many affordable TWS, it is important to make sure that you are not sacrificing quality for a low price. Some brands offer excellent sound quality and features at competitive prices. Do your research and read user reviews to ensure that the TWS you choose offers good value for its price.

According to statistics, 80% of drivers are worried about their phone's battery power while driving. Installing a charger in the car is very convenient. Whether you are going out or driving long distances, you don't have to worry anymore about your phone running out of power. However, in recent years, safety accidents such as cars catching fire due to car chargers have continued to occur. Then, how to identify car chargers that do not meet the requirements? (1) Falsely marking the load capacity. Some manufacturers will falsely mark the load capacity of the car charger, namely the current and output power. Such car chargers may not be able to provide enough current for devices such as mobile phones, causing the charging speed to be slow or not charging at all. In addition, if the car charger charges multiple devices at the same time, there may be a danger of overheating, short circuits or explosions. Overvoltage strength that does not meet the standard. When the car is started, the electrical system in the car will instantly generate a large voltage, which will have a certain impact on the car charger. If the product does not meet the overvoltage strength standard, a short circuit may occur when the car is started, causing a fire or self-ignition. A problem that can cause the entire car to burn out quickly. (2) No protection device. There is no fuse or other overcurrent protection device in the car charger. When there is a problem with the line inside the car charger and the abnormal input voltage causes a short circuit, it cannot cut off the electric current quickly. If this situation occurs in a running car, the damage may not only be the car charger itself, but also the car's power supply system and cause the vehicle to suddenly lose control. (3) The fireproof performance is not up to standard. If the fireproof performance is not up to standard, the most likely situation that occurs after the car charger has a problem is that it burns itself out. Then, How to choose a qualified car charger? Pay attention to the following 2 points: Overload function protection. Avoid choosing a car charger with a size that is too small, this product may not have an overcurrent protection device. A qualified car charger must have a fuse (separator), when the current is too large, the fuse will melt immediately and act as a protection. Do not pursue large current excessively. It is recommended that vehicle owners do not blindly pursue large current, interface and many charging speed functions. Large currents that have problems may cause greater danger. Finally when using the car charger, you should start the vehicle first, then insert the car charger, and unplug it in time after parking and finishing use. Especially in rainy days, lightning and hot weather, you should stop using the car charger product.

Why use a noise-canceling Bluetooth headset but still be able to hear your own voice? In the past two years, Bluetooth headset technology has been increasingly developed, in addition to battery life and sound quality, but in terms of "noise reduction" function seems to be indispensable for buyers to buy Bluetooth headsets. However, when wearing a noise-canceling headset, we also have some questions, such as: "Why can I still hear the surrounding sound after wearing a noise-canceling headset?" "Why can't people's voices be suppressed by the headset? Before answering these questions, let's first understand, What is the principle of noise reduction? Sound is transmitted through sound waves, while noise reduction collects external sounds through the microphone. Then the system generates an inverse sound wave that matches the external sound to the audio output. The two sound waves work together to reduce noise and make the sound from the speaker clearer. What kind of noise can be overcome by noise reduction? The frequency range of current noise reduction headsets is generally 50Hz ~ 1000Hz, this frequency is considered low to medium. Since most of the vehicle and environmental noise in life is in the range of 100Hz to 1000Hz, the shielding effect of noise-canceling headsets on this type of noise is relatively obvious. For medium and high frequency sounds, such as human voice, the frequency range is 100Hz ~ 8000Hz, which is obviously beyond the sound frequency range of noise-canceling processing, so the shielding effect of noise-canceling headsets on such sounds will be relatively different. Why is the human voice not blocked by noise-canceling? The sound dampening requires fast feedback and offsetting direct sound requires the sound vibration frequency to be relatively slow, so that low frequency sounds are easier to process in a fast time than high frequency sounds. Of course, this is not easily detected by human hearing. Most of the environmental noise frequencies in life are in the range of 100Hz to 1000Hz, and the active noise reduction function is enough to isolate most of the noise. If the earphone completely blocks the human voice, it will bring bad impact to the user. In many occasions, we need to selectively obtain some information through external sounds, which is why some noise-canceling headsets on the market will add an "ambient sound" mode. For example, the VIVAN Liberty T660NC noise-canceling bluetooth headset has the dual functions of ANC active noise reduction and ENC environmental noise reduction. The hybrid ANC Hybrid active noise reduction depth can reach -42dB, which can effectively filter out 90% of environmental noise. In terms of technology, VIVAN Liberty T660NC uses four-microphone ENC call noise reduction, which can effectively filter out environmental noise and accurately capture human voices, achieving crystal clear voice calls. In the "ambient sound" mode, you can hear ambient sounds without taking off the earphones, such as car horns and so on. The latest Bluetooth 5.3 version, lower power consumption, lower latency, faster transmission. The battery life is also longer, can last up to 6 hours + 36 hours. Speakers made of 10mm titanium film copper, clear vocals, strong bass, balanced hearing with 3 frequencies. In addition, the VIVAN Liberty T660NC has gone through several times of structural design adjustments and ergonomic tests to achieve the perfect balance between function and comfort. Therefore, complete noise cancelling is not suitable for us to use when carrying out daily activities. . When we are going to buy a noise cancelling headset, in addition to looking at the configuration parameters, we also need to consider sound quality, connection stability, usage experience and battery life.

In daily driving and when going home, many car owners experience situations where the air pressure in the car tires is insufficient. This will cause a decrease in driving safety factors, a significant increase in fuel consumption, and will have a bad impact on the car tires. Carrying a portable car tire pump in your car is a great solution. This car tire pump works through internal operation, and uses atmospheric pressure to fill car tires, balls, or even rubber boats. So what do you need to pay attention to when you want to buy a car tire pump? Power The power of the car tire pump is determined according to the type of car, therefore when you want to buy a car tire pump, you must first consider the size of the car. If the car is small, you can choose a low-power, cheap and energy-efficient single cylinder, that's enough; but if the car is medium or large, you need to use a high-power two-cylinder, if you use a tire pump that is not suitable for the size of the car, it will waste electricity in vain. Pump speed Tire pump speeds are generally different, divided into low-power and high-power tire pumps. If the size of the car tire is large, it is recommended to use a high-power tire pump to fill the tire faster. Generally, those above 225 are more suitable for using a high-power tire pump with a speed above 35L per minute, so what you need to pay attention to is the inflation speed of the tire pump Function Car tire pumps must be multifunctional, for example there must be LED lights and warning lights, this is useful for us to use at night. Equipped with various forms of tools for pumping air, so that it can be used to fill air for car tires, motorbikes, bicycles, swimming floats and ball toys. Connectors Connectors are the most commonly used parts of air pumps, so their quality is very important. A good connector is made of pure copper, which is durable and has good conductivity and heat dissipation. Why is the quality of the connector important? Because to prevent inaccurate measuring instruments (numbers can be wrong), if it is made of ordinary iron which can easily deform, so you should really pay attention to it when buying a tire pump. Cable length The tire pump cable must be long, and preferably more than 2 meters to meet the needs of all four wheels of the car. Tire Pressure Gauge For vehicles without a tire pressure monitoring system, the tire pump must have a feature to check the tire pressure at any time. The digital type is easy to carry and lightweight. The digital display is more intuitive, but the measurement is limited and there may be errors, so the mechanical accuracy is better.

Listening to headphones at high volume for a long time will cause damage to our hearing. According to the World Health Organization's recommendation, the volume setting should not exceed 60% of its maximum volume to maintain the safety of our hearing. But in general, when in a fairly noisy environment, usually in order to hear a clear sound we will set the volume beyond the maximum limit. Technology makes it easier for us, now there are noise-canceling Bluetooth headsets. This headset has a feature with a good sound-canceling effect so that when you are in a noisy room you don't need to increase the volume above the maximum. For people who often use headsets in noisy places, this headset not only gives you a more immersive sound listening experience but can also protect your hearing. This noise-canceling Bluetooth headset is divided into active and passive sound dampeners. When we use a headset equipped with silicon rubber, it can help reduce outside noise but can cause ear discomfort due to the strong pressure from the silicon rubber. ANC and ENC technologies are now widely used as sound dampeners. ANC noise dampening is a technology that functions to neutralize noise frequency wave signals from sound sources, and to eliminate sounds from outside so that listeners can listen to sound immersively. ENC noise cancelling, also known as environmental noise cancelling, can effectively reduce noise by up to 90%. A good noise cancelling headset is one that can make you feel calm, so you can concentrate on doing other work. When the surrounding environment is quiet, there is only the sound of music that can make you stairway to heaven. VIVAN Liberty X1 is equipped with ENC noise reduction feature.
