There are too many types of Bluetooth headphones. You may be confused, which is why I am here today to talk to you about how to pick a Bluetooth headset.
One of the biggest differences between Bluetooth and wired headphones is stability and delay.
Bluetooth headphones with poor stability are often disconnected.
As for the delay, no one would want the avatar box to hear the shot for two seconds when they “eat chicken,” or the second subtitle disappears while they watch the video, and the earliest line has just been spoken.
If you want to improve stability and further reduce latency, you need stronger Bluetooth technology in your headphones.
Not long ago, the official organization SIG Bluetooth declared that every 4.1Bluetooth version would expire.
Therefore, the intended wireless headphones are Bluetooth 4.2 and Bluetooth 5.0.
Bluetooth 5.0 compared to 4.2, the transmission rate is twice as fast, the transmission distance quadruples, while the reduction of power consumption and energy-saving and also the ability to interfere has been improved.
When purchasing Bluetooth wireless headphones, headphones that support Bluetooth 5.0 in terms of delay and stability are higher than 4.2.
Fortunately, models in which the iPhone 8 and mechanical men’s phones with Qualcomm flower or Huawei Kirin processors support Bluetooth 5.0 technology for the last two years.
If your phone does not support Bluetooth 5.0, don’t panic, as it is also backward compatible and downgraded to 4.2.
So either your phone supports it or not, I recommend you pick a headset that supports Bluetooth 5.0.
In addition, the “true wireless” Bluetooth headset now being talked about on the Internet is based on Qualcomm’s TWS True Wireless Stereo technology.
Conventional Bluetooth headphones can only be connected to a single headset, and the left and right headphones can synchronize sound by connecting the cable.
Simply put, the TWS Bluetooth headset connects one of the headphones to the phone because the main receiver and also the main headset is connected to the remaining headset, thus realizing the wireless disconnection of the right and left channels.
It is additionally as a result of split headphones can be divided into primary and secondary headphones, so if a longer period of time, the battery loss of the two headphones will be completely different.
TWS and Technology developed on the idea of TWS, use each headphone as the main headphone to connect it to the phone.
Delay and power consumption are reduced by simultaneously avoiding different battery losses.
Currently, TWS headphones have reached a level of 100 yuan.
Hundreds of high-priced Bluetooth headphones use most TWS and technologies, due to the choice of TWS and Bluetooth headphones.
ii: Sound Quality
Perhaps many of us assume that the headphones are Bluetooth, but we agree that the sound quality is not the sound quality.
In fact, you’re wrong, completely different Bluetooth headphones, the difference in sound quality is also quite large.
If the standard of sound supply is the same, the sound quality depends primarily on the cryptographic format of the transmission and also on the sound generation unit of the headset.
As stated in to the ongoing audio encoding approach of headphones, the output level from bad to good mainly includes AAC, SBC, aptX, HWA, and LDAC.
Among them, SBC and AAC are the previous basic encoding formats that belong to lossy encoding.
On the other hand, Qualcomm’s aptX achieves higher-quality output without compromising sound quality by compressing the audio file and retains more detail than the first two types of encoding.
AptX can also be divided into traditional aptX, high-quality aptX-HD, and low latency aptX low latency, each of which has its own characteristics.
Sony’s LDAC and Huawei’s HWA encoding support higher-quality transmission, which is currently the highest bit rate technology.
For the iPhone, however, only SBC and AAC encryption and decoding technologies are supported.
These two codes are supported by almost all Bluetooth headphones, so you don’t have to worry about which code to choose when choosing.
On more open Android, aptX and LDAC are supported in addition to SBC and AAC as long as the system is Android 8.0 or higher.
In addition to the encoding format, the headphone sound unit is also an important reason for the impairment of sound quality.
The usual voice units are movable coil and movable iron as well as ring irons. Each voice style has its own characteristics, and the feeling it conveys to people will be different.
But if you don’t really care about sound quality, coding and voice units are less important, since the sound quality of Bluetooth is not as good as wired.
In addition, for a few hundred dollars Bluetooth headphones, the difference in tuning can be the most important factor in determining your sense of hearing.
Of course, in many cases, we purchase Bluetooth headphones for convenience.
The quality of the sound is very important, but when we decide and purchase, we should not blindly pass over relief for the sake of sound quality. On these two points, it is recommended that you try to find opportunities for offline preplay as much as possible.
iii: Noise Reduction and Waterproofing
In addition to the above, other features of headphones are just as important, such as noise reduction and sealing.
The noise decrease is divided into active and passive noise reduction, about all headphones have a sure physical passive noise reduction.
In general, passive noise reduction is also very useful in general.
But if you have a high demand for noise cancellation, I’m sure you’ll need to see if the Bluetooth headset has active noise reduction technology.
In addition, for anyone who likes to wear headphones to exercise, sweat, this is safe, if the headphones do not seem to be waterproof, this factor is easy to scrap.
At this point, the waterproofing of the headphones must be at least IPX4 and higher.
How people choose between headgear and grounding depends on their daily needs.
After all, there is such a wide range of Bluetooth headphones. Do you know that you have to choose Bluetooth headphones when reading this article?
