In fact, there are many kinds of Bluetooth headsets to solve these phenomena, but most of the effects are not very ideal. Old fellow headset itoos, headset design, and ear design are not used today, but they can still be worn and not worn down, which greatly relieves the burden of ears.Headset itoos old fellow Bluetooth headset old name is like northeast brand, "old iron" is the meaning of northeast dialect, that is to say, this headset will be a brother like old fellow. Look, the packing is still very beautiful. The collocation of black and orange red is very atmospheric. So, old fellow iron is 6 or 6. Let's have a look.When the package is opened, the earphones inside are arranged neatly, which adds a lot of good impression to the first impression.

When it is worn, it can be inserted into the ear canal, which is not only comfortable, but also allows the voice to enter the ear directly.Let's take another look at the old fellow itoos headset Bluetooth design, which is the unique invisible ear wing. In order to avoid falling, common Bluetooth sports headphones either use ear hook design or ear hook design. The former will make the top of the ear very painful, especially the glasses party, while the latter will prick the ear very uncomfortable and not necessarily stable.This invisible ear wing design is much shorter than the common ear hook. The support position is also at the back of the ear. Combined with the inclined sound guide design, it forms a three-point fixed support with the earphone body, which is very firm. When wearing it, you only need to turn it gently, and it can be firmly stuck in your ears. No matter shaking your head or running, it will not fall easily.In addition to the headset head, the wire control is also an important component of the Bluetooth headset.

Many headsets often have no headset head, but the wired components are damaged prematurely.

I've used a lot of Bluetooth headsets and lost a lot. Several headsets are lost because they hang around my neck when I don't listen. I don't know when they fall off. I didn't notice it at all. The magnetic headset headset old itoos Bluetooth headset can not only use headphones, but also old fellow phones, which can be attached to necks as necklace, and will not be lost and beautiful.Headset design of old itoos iron headset is much more powerful than other similar earphones. It requires a lot of effort to separate. Old fellow earphones are very strong. Silver metal material and cylindrical cavity design are adsorbed together like a work of art. They are very beautiful and not ugly to hang around their neck. Even daughters like to play "kiss" games with their mother with headphones.After talking for a long time, the most important thing is to see how this headset works. Headset old fellow itoos headset headset is very beautiful, especially collocation with light coloured dress, but it is beautiful. It is also a headphone. Earphone is to bring music enjoyment to the ear. Next let's see how old fellow itoos headset Bluetooth is used.Old fellow headset itoos headset cavity is relatively large, slightly prominent, and larger chamber can bring better sound quality, which is directly proportional to.However, although it looks prominent, it does not affect the wearing feeling at all. Especially when girls wear it, if their hair covers the headphones, they can't see that they are wearing headphones. When their hair is lifted, the silver headphones seem to be an ornament on their ears, which is very beautiful.Let's take a look at the earphone itself. Looking from the front of the sound guide tube, you can see the internal sound hole, fine dust net and uniform sound outlet hole, which can effectively make the sound better transmitted to the ear. The unique inclined sound guide tube design makes the ear better receive the sound.To test the sound quality of headphones, there are three factors, good headphones, good players and good music. Mobile phone headset is not old enough to speak of this itoos old iron Bluetooth headset. The most popular listening tool is the mobile phone. So I also test it with my mobile phone. Music also selects some common old fellow songs to better judge the quality of the sound.As we all know, it is best to burn the headset for a certain time before the sound test, so as to obtain the best sound quality. Although there is no need to burn in the Bluetooth headset, in order to obtain the best test effect, I still used the burn in software for dozens of hours, and then tried to listen to the songs.During the audition, the first music I chose was Cai Qin's forgotten time. This song is mainly used to test the voice and tri band feeling. It is a very clear tri band song. Old fellow headset is still very good, especially after the initial voice of the solo, very touching and clear. It is very clear that itoos's old Bluetooth headset is excellent. In the back music part, the tri band is also very clear, and the overall silver performance is very balanced.Secondly, I chose a classic old song, Hotel California. The guitar in the early stage and the singing in the later stage of this song are very test for the earphone. After audition, when the guitar solo was played in the early stage, it felt like plucking the heart strings. When the drum sounded, although there was no shock like super bass, the performance of bass was also commendable. The details of every musical instrument can be clearly heard. Itoos's Bluetooth headset old fellow is doing well in different frequency bands.Of course, if possible, we still use professional hifi music player to listen to music, so we can get better music effect than mobile phones. After listening to dozens of songs, old fellow itoos Bluetooth headset is more suitable for listening to pop songs, and also has strong rhythm songs, which can get the best sense of hearing.In addition to listening to music, Bluetooth headsets have many functions. For example, when playing games, there will be no headphone cable to hinder operation. For example, when watching movies, you can also be free and unrestricted. The itoos old iron Bluetooth headset has high face value and high strength, and is a very good game old fellow and Movie Companion product.After experiencing the sound quality, there is another important reference basis for Bluetooth headset, that is, endurance. Mobile phone headset on the old side of the itoos Bluetooth headset has a microusb charging port. It can charge a battery charger at any time, and charge speed is very fast. After testing, the old fellow can fill the headphones by using 5V1.5A charger for about 1 hours. It is also very convenient that when connecting Apple phones and some Android phones, the remaining power of the headset can be displayed directly on the top of the phone, which is very intuitive.Then, for the endurance test, I used the method of continuous use to test. Of course, I can't listen to songs continuously, so I turned on the sound of my headset to the maximum, and then connected my mobile phone to play movies for fatigue test. At about 8 a.m. at work, it was played at full power. It was played continuously until about 3 p.m. when the headset sent out the prompt sound of insufficient power, that is to say, the maximum volume can be played continuously for about 7 hours, but when the prompt power is insufficient, it can still be played for more than 10 minutes, So itoos's old fellow headset is really good.After a headset headset, I have tested the appearance, detail design, comfort, function, sound quality and endurance. The whole feeling is that itoos old fellow Bluetooth earphone is a very suitable earphone for listening to music. It is very good and quiet to listen to music in quiet music or in running. The price of this earphone is very close to the people and cost-effective. It's worth starting with.
