There are too many kinds of Bluetooth headphones. You may be confused, So today I’m here to talk to you about how to choose a Bluetooth headset.
One of the biggest differences between Bluetooth and wired headphones is stability and delay.
Disconnection often occurs in Bluetooth headphones with poor stability.
As for the delay, no one would want the avatar box to hear the gunshot for two seconds when they “eat chicken”, or the second subtitle disappears while watching the video, and the first line has just been spoken.
If you want to improve stability and further reduce latency, you have to use stronger Bluetooth technology on your headphones.
Not long ago, SIG (Bluetooth official Organization) declared that each one 4.1Bluetooth versions would be phased out.
Therefore, the thought wireless headphones are Bluetooth 4.2 and Bluetooth 5.0.
Bluetooth 5.0 compared with 4.2, the transmission rate is double as fast, the transmission distance is quadrupled whereas reducing power consumption and power saving, and also the ability of anti-interference has been enhanced.
When buying wireless Bluetooth headphones, headphones that support Bluetooth 5.0 in terms of delay and stability are higher than 4.2.
Fortunately, models when the iPhone eight and mechanical man phones with Qualcomm flower or Huawei Kirin processors over the past 2 years support Bluetooth 5.0 technology.
If your phone doesn’t support Bluetooth 5.0, don’t panic, because it’s also downward compatible and downgraded to 4.2.
So whether your phone supports it or not, I suggest you choose a headset that supports Bluetooth 5.0.
In addition, the “true wireless” Bluetooth headset now referred to on the Internet refers to Qualcomm’s TWS (True Wireless Stereo) true wireless stereo technology.
Traditional Bluetooth headphones can only be connected to a single headset, and the left and right headphones can synchronize the sound through the connection of the wire.
The TWS Bluetooth headset, to put it simply, connects one of the headphones to the phone because the main receiver, and also the main headset is connected to the remaining headset, therefore realizing the wireless separation of the left and right channels.
It is additionally as a result of split headphones may be divided into primary and secondary headphones, so when a protracted time, the battery loss of the 2 headphones will be totally different.
TWS and technology, developed on the idea of TWS, uses each headphones as main headphones to attach on to the phone.
While avoiding different battery losses, delay and power consumption also are reduced.
At present, TWS headphones have achieved 100 yuan level.
Hundreds of high-priced Bluetooth headphones use most TWS and technology, conditional in fact select TWS and Bluetooth headphones.
- Sound quality
Perhaps many of us assume that the headphones are Bluetooth, however conjointly say that the sound quality isn’t sound quality.
In fact, you’re wrong, totally different Bluetooth headphones, the distinction in sound quality is also quite large.
When the standard of the sound supply is that the same, the sound quality primarily depends on the cryptography format of the transmission and also the sound generating unit of the headset.
According to the present audio coding mode of headphones, the audio quality output level from low to high mainly includes SBC, AAC, aptX, HWA and LDAC.
Among them, SBC and AAC are the previous basic coding formats, which belong to lossy coding.
On the other hand, Qualcomm’s aptX, by compressing the audio file, achieves the output of higher quality sound quality without affecting the sound quality, and retains more details than the first two kinds of coding.
AptX can also be subdivided 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 coding support higher-quality transmission, which is currently the highest bit rate audio transmission technology.
For iPhone, however, only SBC and AAC encoding and decoding technologies are supported.
These two encodings are supported by almost all Bluetooth headphones, so you don’t have to pay attention to which code when choosing.
On more open Android, aptX and LDAC will be supported in addition to SBC and AAC, as long as the system is Android 8. 0 or above.
In addition to the coding format, the headphone sound unit is also an important reason for affecting sound quality.
The common vocal units are moving coil and moving iron as well as ring iron. Each tuning style has its own characteristics, and the feeling it brings to people will be different.
But if you’re not particularly feverish about sound quality, coding and vocal units are less important. After all, Bluetooth’s sound quality is not as good as wired.
In addition, for a few hundred dollars of Bluetooth headphones, the difference in tuning may be the most important factor in determining the sense of hearing.
Of course, in most cases, we buy Bluetooth headphones for convenience.
Sound quality is very important, but when we choose and buy, we should not blindly ignore the comfort of wearing for the sake of sound quality. (on these two points, it is recommended that you try to find opportunities for offline auditions as much as possible.).
- Noise Reduction and Waterproofing
In addition to the above, other features of headphones are equally important, such as noise reduction and waterproofing.
Noise reduction is divided into passive noise reduction and active noise reduction, almost all headphones have a certain physical passive noise reduction effect.
Generally speaking, passive noise reduction is also quite useful in general.
But if you have a high demand for noise reduction (I’m sure you will), you need to see if the Bluetooth headset has active noise reduction technology.
In addition, everyone who likes to wear headphones to exercise, sweat down that’s sure, if the headphones don’t seem to be waterproof, this factor is simple to scrap.
At this time, the waterproof level of headphones is needed to be a minimum of IPX4 and above.
As for the way folks choose from headwear and earthing, it depends on your daily needs.
Finally, there are such a large amount of choices for Bluetooth headphones. does one knowledge to decide on Bluetooth headphones when reading this article?
