1. What is a true wireless Bluetooth headset

Here we mainly introduce portable headphones, and the evolutionary history is probably like this:

 

Compared with traditional wired and neck-mounted semi-wireless headsets, true wireless Bluetooth headsets are inferior to TWS technology.

 

To put it simply, it is a true wireless stereo. It does not require a cable as a transmission medium, and directly connects the mobile phone and the headset with the Bluetooth module. The old Bluetooth headset will also be divided into a main headset and a secondary headset. Headphones work independently.

 

2. What points need to be considered when purchasing a true wireless Bluetooth headset?

sound quality

Noise reduction

delayed response

wearing comfort

battery life

Waterproof level

 

 

1. Sound quality

When it comes to sound quality, you need to first understand the Bluetooth audio decoding format. At present, basic tws wireless bluetooth earphones are compatible with Bluetooth 5.0 version.

 

Among them, the audio decoding technology is always updated and iterated. This thing is more complicated to say, and it is not too helpful for purchasing headphones. Let's focus on it.

 

The main issue here is adaptation

 

Apple: AAC

Android: SBC, APTX, LDAC, LDHC

Huawei: HWA

At present, APTX, LDAC, and LDHC are more inclined to lossless sound quality. Many of them will use APTX as a gimmick to promote lossless. It is true that the performance is relatively balanced, but it is not suitable for Apple, and only applies to Qualcomm chips.

 

LDAC and LDHC are Sony's technology, with fast conduction speed and high quality, but there are limitations, only Sony's own headphones support.

 

The minimum Android headset must be SBC, and the sound quality is average, but it should be noted that no matter how good the decoding format is used in the true wireless Bluetooth headset, the sound quality effect is not as good as that of the wired headset. This technical barrier has not been solved until now. .

For game enthusiasts, even APTX can only be said to be low latency. For high requirements, it is recommended to directly choose wired headphones of the same price.

 

2. Noise reduction

It’s Apple’s pioneering noise-cancelling headset. I have to say that it is really necessary, especially for those who have high requirements for call quality. If it can weaken all kinds of annoying noises, it will be a pleasant experience.

 

Noise reduction is divided into active noise reduction and passive noise reduction. We will not mention passive noise reduction for the time being. To put it bluntly, you can also achieve passive noise reduction with earplugs; and active noise reduction is a truly valuable technology, especially Wind noise, headphones that want to meet this requirement cost at least a thousand yuan.

 

3. Delay

It can be said that no matter how expensive the tws true wireless stereo earphone is, no matter how the business advertises, the delay will definitely exist, more or less, and the impact will vary from person to person; simply making calls, listening to songs, headphones for a few hundred dollars are completely Satisfaction, even if there is a delay, you will not feel it.

 

If you are a game lover, you are more sensitive to listening position and prefer to use tws bluetooth earbuds. In addition to the APTX transmission protocol mentioned above, you must also comply with the matching of the device ecology. For example, Huawei headphones are used on Apple mobile phones. The delay must be much worse.

 

4. Wearing comfort

Many people wear true wireless earphones all day long, which has high requirements for the comfort of the earphones.

 

Comfort level: semi-in-ear> in-ear

 

The semi-in-ear type has no silicone cover. When wearing it, the intrusion of foreign objects is smaller than that of the in-ear type, which is theoretically more comfortable. Before buying wireless earbuds online, read reviews on the fit to see which silicone case is right for you.

 

Many in-ear styles include inner ear stabilizers, which can be placed in the ear and rotated a little for the perfect fit.

 

5. Battery life

The battery life of mainstream headphones is between 4-8 hours, and the charging box can be charged at any time, which can generally be used for about 20 hours. Note that there are two types of battery time advertised for commercially available true wireless headphones: 1. The power of the headset itself; 2. The total power of the headset plus the power of the charging box. So when buying, pay attention to which battery specification refers to to avoid buying the wrong one.

 

In addition, you can also pay attention to whether the headset has the function of fast charging, so as to prevent the dilemma of forgetting to charge the headset when you need it urgently. At the same time, it also reminds friends who travel/fly long-distance travel, if you want to enjoy more than 5-6 hours of continuous peace, you can choose ANC active anti-noise headphones, the battery life will be longer.

 

6. Waterproof level

 

When we buy wireless sports headphones, we often see specifications marked IPXX. The first number represents solid particle protection, which is the dustproof level, the second number represents liquid penetration protection, which is the waterproof level, and 4 is general protection. Splashing water, 5 or more can be washed and cleaned, 7-8 can be used in the water for a period of time, the larger the number, the higher the protection level.

 

It is recommended that IPX4 and IPX5 waterproof grades are enough for daily use.
