Due to some of the habits and living conditions of each person, it is necessary to use headphones to make phone calls or listen to music. However, wired headphones are not so practical, especially in crowded buses and subways. Fortunately, bluetooth headsets have grown rapidly over the years, and the standard bluetooth specs have steadily increased. Let's take a look today BOSE Soundsport Wireless Bluetooth Headphones. (Bluetooth Hat Headphones, Bluetooth Headphones, TWS Bluetooth Earbuds, Mini Bluetooth Headset, Bluetooth Earbuds, Wireless Earphones)

First introduce the main task, bose soundsport wireless.


Bose SoundSport Wireless Headphone - Aqua Blue Earbud Bluetooth Headset Sports Headphone Smart Headphone 1388 Yuan Jingdong Direct Link


1, appearance display

Box, BOSE's box has always been no less than this, more sophisticated consumer goods. But this is the same as Sony's warranty on plastic packaging.

Inner packaging, some useless paper (also a warranty card), charging cable and a moderately soft storage box

The protagonist, who did not buy black this time, personally feels the water blue looks good

2, use feel & contrast
2.1, appearance & wear

Buy this is because of running needs, previously connected to buy two Sony's sbh70, that is really easy to use, but also cheap, excellent water resistance washed a lot of water outside the outdoor two Shenzhen rainy season, there is no problem, unfortunately Lost. But the big problem with sbh70 is that the sound quality is really inferior, and it is the same headpiece as the earpod. It is not soundproofed. In a noisy place such as a car, the sound needs to be very loud, and the pro-test is harmful to hearing.

The later ex750bt was in the ear, no active noise reduction, but the noise and sound quality compared to sbh70 have greatly improved. The problem still exists. It is not convenient to wear and carry. The girlfriend said that this is a hard and big circle (she is a fruit powder and laughed at the appearance and design of all my Sony things), and it is not waterproof. As a sweaty jogging and summer use, I bought a waterproof one.

The appearance of BOSE has always been quite good. Personally feel that the combination of rounded and Founder is better. However, this wearing is really like a U disk, as shown below, is protruding, mind students still have to look at more.

Switch button and two indicator lights, wearing more comfortable, large, medium and small size of the three ear plugs, there is always a fit, not loose.

The charging port cover, connected to the headphones, is generally sealed. However, it is generally not possible to see water in the position below. The earphones are easily stained with gray.



The back of the clip, very good use, plus a relatively thick but relatively soft line, people feel at ease and there is little stethoscope effect, this is really good, and soundtrue comparison.

Control buttons are usually the same three, feel hard and deep key thief, feel bad, NFC is also here.

Do not know if it is an example, my switch button has no sense of passage, hard, there is a kind of strongly press the resistance screen.

It's really comfortable to wear, but after all there are other things in the head that are heavier than normal headphones, so don't expect to get the comfort of the doctor's wired in ear.

2.2, Use & Application

Dr. does not love to give product label technology, this headset Bluetooth standard is V4.2, basically the latest, does not support any other codec technology, but for ordinary fungus (such as me) is absolutely enough, and this sense of hearing can not be written There is no big problem, and the high frequency is slightly weaker. I don't know if buying a pot would be better.

It is very convenient to use. There are clients on iphone and Android. You can connect two devices at the same time. Press the headset power button once to switch the device. In the client can read the headset production information, to the headset to upgrade the firmware or something, in general, is very good, the two client interface functions are basically the same.


The official announcement of charging for 6 hours in 2 hours is basically reliable, but there is a problem, the sound is relatively small, when the outdoors is noisy, the iphone needs to open half of the sound to hear it.

On top of that, I sent a storage box (or a bag), but those who didn't want to use it wouldn't use these troublesome things. According to the quality of this line, the top pocket is ok, as long as you don't put it together with the key.


Waterproof, Dr. did not standard ipx grade, only said that anti-sweat and rain, so even if the level of evaluation is not high. There were no problems with the actual acid rain test outside these two days. The headset still has problems with the batch seals produced before September last year. If you want to buy it, you still need to apply it to see the date of manufacture. It is said that all failed batches were recalled and destroyed, but NOTE 7 has a collection and it is still good to see.

The hydrophobic mesh on the mouth of the cavity is best not to be washed and washed.

3, written in the back

Encrusted with some private goods, he also bought, used a few Bluetooth headsets, things are really convenient, there are some tiny experience to share.

3.1, Standards and Technical Specifications

The Bluetooth standard has been updated relatively quickly in recent years, mainly focusing on the transmission rate, power consumption and anti-jamming. Because of the frequency band, many efforts have been made in several years of anti-jamming. The low energy (LE) version The introduction of power consumption also makes the control okay, but the most important issue is the transmission rate, which is what we often say.

Listening equipment has now become metaphysics, but the decisive factor in quality is mainly the sound source, decoding front end, wire and sound unit, and the Bluetooth headset and wire are replaced with Bluetooth transmission, and the bandwidth plays a decisive role. What is a pity is that the latest 4.2, although the upper limit of the standard is very high, but the air data rate is more moving, 1mb/s (the latest 5.0 seems to be at 2mb/s, 1B=8b), and the actual application throughput is much lower. And after decoding a few megabytes of music, it is not only the size of the original file. Underneath this, the sound quality can be imagined. I don't have any hope for the sound quality of Bluetooth. My own ears are ordinary fungus. I can say it is a very good match.

There are a few new Bluetooth encoding and decoding methods that you want to mention. Remove the ordinary SBC.

AAC, Apple, and "Nokia" are used, and some are advanced. After all, people's names are called seniors, and their quality is better than SBC.

Aptx has recently been relatively hot, but it needs both chip support, Qualcomm to do more chips. Iphone not this, so headset support is useless;

LDAC, as a cable dog, really squirt, then buy 750bt a big reason is this, after all, people's theory transmission at 990kb / s (aptx is 384), even listening on Z5c, do not know if it is not brain release Reasons, the intestines are clear. Now only Sony has this, but has given Google technology, Android 7.0 should be on the headset support. So you guys, Sony Dafa is good.

Because you are not studying this, there may be some deviations in the report. We can see that one is probably better, and there are knowledgeable side-friends.

3.2, a few small experiences

If you just run to listen, the environment is not noisy, really strongly recommend the price of sbh70,400, leather can not afford to buy a loss can not be taken advantage of, anyway, will not go to listen carefully.

Usually commute, ex750bt is still quite worth recommending, after all, with a bag, there is a place to install, or set in the neck when the neck ring is also OK, sound quality, technology and faith are enough. There is also a wireless module of the same paragraph. Some time ago, Zhang Dama had a big brother to pick up the head of ie80, of course, can get better sound quality.

Last year, the impulse consumed an AKG Y50BT. At the time, he wanted to buy a headset, but he didn't want to buy Baotou because it was too hot. He hesitated for a while between this and beats solo and Dr. on ear, or bought this one ( Because of the support for aptx), its implementation regrets that it should buy beats because the computer does not support it. The advantage of wearing ear or ear covering is that the unit is large, the sense of hearing is still improved, and the battery life is refreshing. Generally speaking, there are 30 hours of it, but you should really consider comfort, not just clips. Head, summer is really hot. Then there is the street, I may be because of the burden is relatively heavy, can not go out, I feel like the eight ring version of the antenna baby, can not come this. The use scenario is about playing games in the room during the summer without disturbing the family.

The above are all used by myself. For apple users, airpods are king. If the ears are of the right size, it is really good, easy to use, and not lost.


to sum up

Dr. Earlier this earphones than their own QC30, with the earplugs, less signs of active noise reduction, there is not a strong sense of existence, but there are his own application scenarios, and the price is a lot cheaper, or have their own competitiveness. This price does not sell after Jabra, Jaybird sells less (may be more later), beats x that no sweat or something, B & O H5 is great, but also a lot of expensive. Of course, because of their own choices, there will be a subjective bias, which can only serve as a reference for everyone.

The first time I wrote this, it was more chaotic, please see the official magistrate Hai Han.
