Friends who often use headphones to listen to music know that the effect of playing music with headphones is very different from that of speakers. Especially in terms of the expressive force of sound field, earphones are not as natural as speakers. This is because when we play music with speakers, the sound first spreads through the air before reaching the human ear. In this process, the refraction, diffraction and diffraction of sound waves by human auricles, ear canals, human skulls, shoulders, etc. will have a certain impact on the sound. When we listen to music with earphones, the sound is directly transmitted to the ear by the earphone driver, and the impact of air, pinna, skull and shoulder on the sound disappears completely. In this case, not only the sound field is not natural enough, but also the distance and direction of the sound cannot be accurately judged through the earphones.

So is there any way to change this defect of headphones? A 3D wireless recording headset called ALAYA came into our sight. This is a core product launched by Sabin Technology, known as the pioneer of portable 3D recording, which can accurately record sound field and sound source orientation information in standard format recording files with classic stereo recording technology.

Why is this earphone so awesome? Because this is the world's first two-way wireless audio transmission equipment. SWISS transmission protocol promoted by Sabin Lab can realize ultra-low delay high-quality wireless audio transmission and truly restore the recording scene of sound. The voice input design of the humanoid head also minimizes the defects of the headset in restoring the sound field.

In terms of appearance design, this ALAYA3D wireless recording headset adopts the neck hanging design that most wireless Bluetooth headset manufacturers are using. Moreover, this headset is very light, only 32g, and it can hardly feel the weight when hanging on the neck. It is convenient to carry and not easy to lose.

At the same time, when the earplug of the headset is not in use, it can be easily inserted into the storage hole of the ALAYA3D wireless recording headset, and it will not fall off. It is convenient to take it when you use it.

The unique earplug design angle does not need to squeeze the ear and the earplug, just gently put it into the ear, and it will be firmly stuck and will not fall off. This design greatly reduces the ear pressure caused by wearing earphones for a long time.

Two pairs of high fidelity earplug sleeves and one pair of original earplug sleeves are included. A total of three pairs of earplug sleeves with different sizes can basically meet the needs of all ears.

After the earplug is put into the storage hole, the extra part will not appear too abrupt. At the same time, because the storage hole is circular, the angle of the earplug can be adjusted to a comfortable angle for the neck.

Although the ALAYA3D wireless recording headset is lightweight, its functions are not ambiguous at all. The right side integrates the headset's power on key/Bluetooth pairing key (on/off), recording key (red dot), volume adjustment key (+-) and headset charging port.

Micro USB charging port adopts a hidden design, which can be covered to prevent dust and other sundries from entering when not charging at ordinary times. At the same time, the sealing performance of the rubber seal cover is very good, and it should be no problem to protect the general sweat and rain.

The left side of the ALAYA3D wireless recording headset is integrated with the phone answer/music playback pause button and the back/fast forward button. Yes, although this is a 3D wireless recording headset, it is also an excellent Bluetooth sports headset. Therefore, whether it is 3D recording or music listening, the ALAYA3D wireless recording headset has all the necessary functions.

When the ALAYA3D wireless recording headset is used for the first time, it should be fully charged before use. When charging, it should be noted that ALAYA's own charging cable must be used to connect to the power adapter. At the beginning, I tried to charge ALAYA directly with other mobile phone USB charging cable, but the charging indicator could not be lit.

When charging correctly, the red indicator light next to the recording key is always on.

The charging time is about 2 hours, and the indicator turns green and is always on. This ALAYA3D wireless recording headset can record for 10 hours, play music for 16 hours, talk for 20 hours, and standby time for 600 hours. This is too powerful. My iPhone needs to be charged several times. It is estimated that the ALAYA3D wireless recording headset can continue to stand by.

Don't ask me how to distinguish the left and right wearing directions of the ALAYA3D wireless headset. The letters indicating the wearing direction are clearly printed on the back of the headset. See the capital letter L?

Although the ALAYA3D wireless recording headset provides three pairs of earplug sleeves of different sizes, it is still difficult to replace the earplug sleeves. Perhaps because of the high fidelity, the earplug sleeves and headphones are connected very closely, with almost no gap, so it is easy to pull them off, but difficult to put them back.

The same song is compared with the ALAYA3D wireless headset with a Bluetooth speaker. Unexpectedly, the sound of the ALAYA3D headset is more intimate, just like a singer whispering in his ear.

Of course, as a 3D wireless recording headset, its main function is to test the recording effect. So I took the ALAYA3D wireless recording headset to record some videos and music in different scenes.

Wearing the ALAYA3D wireless recording headset around your neck is really convenient, and it looks very textured. It looks much taller than the ordinary Bluetooth sports headset.

Before recording, we need to do some preparation work. Charge the ALAYA3D wireless recording headset, and of course, the mobile phone should also be charged. Otherwise, it will not be fun if the power goes out suddenly in the middle of the game. The most important thing is that we should download and install the ALAYA app for mobile phones, because we need to record and manage our video and audio information through the app. The ALAYA3D wireless recording headset supports both ios and Android mobile phone operating systems. You can download and install corresponding applications for your mobile phone. After installing the app, open the Bluetooth pairing between the phone and the ALAYA3D wireless recording headset at the same time, and then connect to use.

After opening the app, we can see many interesting recordings to share. Of course, our own recorded sounds can also be published and shared on the ALAYA website platform. Since my ALAYA3D wireless recording headset is a classic version, not a high profile professional version, my ALAYA3D cordless recording headset does not have the professional version of the sensitivity calibration of the left and right pickup heads: ± 0.2dB Custom output format: AAC/WAV custom video bitrate: Professional recording function options such as 500-5000kbps automatic gain control and active noise reduction on/off options. Therefore, if you want to record your own songs, you still need to choose a quiet environment without noise. In addition, the ALAYA3D wireless recording headset can also be used as a Bluetooth headset to listen to music.

This is the video and voice of the passing traffic recorded by me at the roadside, which is also mixed with the voice of some passers-by behind.

This is the video and sound recorded in KFC's indoor environment, which basically accurately reflects the real-time synchronization of sound generated by the behavior of the characters in the picture.

After coming out of KFC, the night market outside was very busy, with footsteps, hawking, bargaining and dialogue among people around, as well as the whistle of cars on the road in the distance, and even the screaming of children.

Finally, I recorded two songs in my bedroom. Recently, I caught a cold, and my throat was inflamed and my breath was not enough. Although the singing is not so perfect, it can also be clearly felt that the singer is talking in his ear. In addition, the effect of listening to your own recorded songs through the ALAYA3D wireless recording headset is different from that of playing them through the loudspeaker. The effect of 3D headset playing is more realistic and immersive.

In general, this ALAYA3D wireless recording headset is a very powerful holographic recording headset, which can truly and accurately restore the sound environment of the recording scene. The effect of recording personal karaoke is also very good, which is much better than that of singing bar and national karaoke recorded by mobile phone recording software. It is definitely not an improvement in quantity, but a qualitative leap. In addition, this ALAYA3D recording headset has another major advantage. Although it is an in ear earplug design, the mesh design on the back of the earplug will not be completely sound proof. When listening to music, you can also take into account the surrounding environment. Compared with other in ear earphones, the safety of the earphones is much improved. Video live broadcast, holographic conference, voice interaction, online education, professional recording and other scenes, all can be done with one ALAYA3D wireless recording headset.
