In recent years, with the popularization of smart devices and the daily needs of travel and sports, people's demand for Bluetooth headsets has increased.  Sinodec Industrial Co., Ltd. also launched several Bluetooth headsets and Bluetooth sports headsets in 2020, which have greatly improved in terms of sports waterproof headsets and noise-canceling wireless bluetooth earphones.  Was welcomed by customers

So how to choose a Wireless Bluetooth Sport Earbuds, traditional Bluetooth earbuds can only be connected to a single earphone, and the left and right earphones can be connected through the line to synchronize the sound.  The TWS Bluetooth headset, in short, connects one of the headsets as the main headset to the mobile phone, and then connects the main headset to the remaining headset, thus realizing the wireless separation of the left and right channels.

It is also because the split earphones are divided into main and auxiliary earphones, so after a long time, you will find that the battery consumption of the two earphones is different.  The TWS Plus technology developed on the basis of TWS uses both earphones as main earphones and connects directly to the mobile phone.  While avoiding the difference in battery consumption, latency and power consumption are also reduced.  At present, TWS Bluetooth headsets have many price options.

Most of the hundreds of expensive Bluetooth headsets use TWS Plus technology. If possible, choose TWS Plus Bluetooth headsets.  Sound quality is also very important. Many people think that the headset is Bluetooth, and they also pay attention to the sound quality.  In fact, the difference in sound quality between different Bluetooth headsets may be quite large.  In the case of the same sound source quality, the sound quality mainly depends on the encoding format during transmission and the sound unit of the headset.

Regarding the current encoding methods for audio by headphones, the sound quality output levels from low to high are mainly SBC, AAC, aptX, HWA and LDAC.  Among them, SBC and AAC are both basic coding formats earlier and belong to lossy coding.  After transferring from the mobile phone to the headset, the sound quality will be lost and some details will be lost.  Qualcomm's aptX, by compressing audio files, achieves a higher-quality audio output without affecting the audio quality, with more details reserved than the first two encodings.  aptX can also be subdivided into traditional (aptX), high-quality (aptX-HD) and low-latency (aptX Low Latency), each with its own characteristics.  Sony's LDAC and Huawei's HWA encoding support higher quality transmission and are currently the audio transmission technology with the highest bit rate.

However, for iPhone, only SBC and AAC codec technologies are supported.  Almost all Bluetooth headsets support these two encodings, so you don't need to pay attention to which encoding is used when choosing.  .  .  On the more open Android, as long as the system is a mobile phone with Android 8.0 or higher, in addition to SBC and AAC, it will also support aptX and LDAC.  If your mobile phone supports LDAC, choose a Bluetooth headset that supports LDAC as much as possible, so that you can enjoy higher quality sound quality.  In addition to the encoding format, the earphone sound unit is also an important factor affecting the sound quality.  Common sounding units are moving coil, moving iron, and ring iron. The tuning styles have their own characteristics, and they will bring different feelings.  However, if you are not particularly feverish about sound quality, encoding and sounding units are not so important. After all, the sound quality of Bluetooth is not as good as wired.  Moreover, for a few hundred dollars of Bluetooth headsets, the difference in tuning may be the most important factor in determining the sense of hearing.

In most cases, we choose Bluetooth headsets for convenience.  Sound quality is important, but when you buy, don’t blindly ignore the comfort of wearing for the sake of sound quality.

Finally want to say

In addition to the aforementioned, other functions of the headset are also important, such as noise reduction and waterproofing.  Noise reduction is divided into passive and active. Almost all headphones have a certain physical passive noise reduction effect.  Generally speaking, passive noise reduction is also quite adequate under normal circumstances.  But if you have a relatively high demand for noise reduction (I believe you will), then when choosing, you need to pay attention to whether the headset has active noise reduction.  Here is a handy recommendation for Bose's QC35.

If the headphones are not waterproof, they will easily be useless.  At this time, the waterproof level of the headset is required to be at least IPX4 and above.  As for the choice of head-wearing or in-ear type, it depends on your daily needs.  Having said so much, of course, at the end, I still have to choose a few Bluetooth headsets to recommend to everyone. Let’s talk about the ones Tony himself is using. Daily commuting: Sony WI-1000X (in-ear), Apple AirPods 2 (semi-in-ear, true wireless)  , WH-1000X M3 (active noise reduction on head), sports running: Redmi AirDots (true wireless), FIIL T1 (TWS true wireless Stereo, IP65 waterproof)

Finally, there are too many options for Bluetooth headsets. If you need to import headsets from China, please contact us freely.
