Today’s true wireless headset market is fiercely fighting. Some brands are very good, have technology, and have precipitation. They may launch one or two products every year, but they are all high-quality products. The JEET Air 2 bluetooth earbuds that this article will share is from XiaoJie Technology.

XiaoJie Technology has a profound accumulation of software and hardware. XiaoJie Technology, established in 2010, has provided large-scale audio and video technology solutions for many well-known manufacturers around the world. Its self-developed TV software “TOGIC VIDEO” and its own hardware The brand WEBOX smart TV box has already entered thousands of households.

Based on this, after XiaoJie Technology entered the field of bluetooth headsets in the past few years, several products such as JEET Air Plus and JEET Mars have won good reputations.

As a new product of XiaoJie Technology, JEET Air 2 bluetooth earphones is only 60% of the size of ordinary bluetooth headsets and weighs only 3.4g. I believe that friends will find it refreshing after reading it. Without much to say, let’s go into the text and take a look.

1. Unboxing & accessories

JEET Air 2 Earbuds

▲The front of the JEET Air 2 package is very simple, with only the rendering of the headset. The visual contrast between the black headphones and the white bottom plate is also very strong.

▲There is not much information on the product introduction on the back of the box, and the manufacturer’s information is relatively complete.

2. Charging case details & battery life

▲The top of the charging case is the JEET brand logo, and compared to the frosted material of the box body, the carved pattern presents a smooth texture of obsidian black.

▲The charging case is quite user-friendly in the design of opening the lid, and the groove is very helpful for opening the box. The external indicator light is also practical, and you can check the charging progress in real time without opening the lid when charging.

▲The Type-C interface is located on the back of the charging case. It takes 1.5 hours to fully charge the headset and 2 hours to fully charge the charging case. The hinge area occupies a larger position, which will affect the appearance a little.

▲The pairing key of JEET Air 2 earbuds is located at the bottom of the charging case. This design is the first time I have seen it, and it feels very fresh.

▲Open the charging case cover, it can be seen that compared to the hidden storage, the display of JEET Air 2 is more complete. There is also a small space on the edge of the storage slot for easy access to the earphones. There are also “L” and “R” signs inside the charging case to facilitate accurate identification and use of earphones.

▲The energy consumption of products such as earphones is quite small. It can be seen that the battery capacity of the charging case is 300mAh.

▲The headset battery has a capacity of 45mAh, the headset can last up to 7.5 hours in a single battery life, and the overall battery life is 20 hours with the charging case. Of course, this battery life is not particularly long, but considering that this is a super pocket true wireless earbuds, I think this level is actually sufficient.

It is worth noting that the single battery life of the headset is relatively long. I think the use of the headset is 3-4 hours a day. In other words, a single battery life of JEET Air 2 can support at least two days of use. The long single battery life of the headset is also related to the use of the most advanced bluetooth 5.2 technology in JEET Air 2.

▲The total weight of the charging case and earbuds is 38g, and they will not feel heavy when they are carried out in the pocket.

3. Headphone details & functions

▲JEET Air 2 is about the size of a little finger. It adopts an eccentric design and has a matte texture as a whole. The touch area has a “Y”-shaped protrusion, which makes the touch feel very good.

▲JEET Air 2 earphones are also distinguished by the words “L” and “R”, and the charging metal contact area is also relatively large, so it is not easy to contact poorly.

▲The speaker size of JEET Air 2 is φ13.05mm, the thickness is 1.9mm, and the bass performance is predictably strong. It also uses a composite PU+ titanium-plated double-layer diaphragm and uses a stereo sound design, which is very rare in true wireless headphones, especially such a small size.

▲JEET Air 2 supports the latest version of bluetooth 5.2. Compared with bluetooth 5.0, it has added three functions: LE synchronization channel, enhanced version of ATT and LE power control. In actual use, a headset equipped with bluetooth version 5.2 can achieve faster transmission speed, longer distance and lower power consumption.

In addition to supporting bluetooth 5.2, JEET Air 2 also has a double-layer composite ceramic antenna to make the headset transmit more stable signals and stronger anti-interference ability. The control of power consumption can also be further strengthened.

▲The weight of a single earphone of 3.4g makes the JEET Air 2 look very small when it enters the ear, and it is almost completely embedded in the auricle. I conducted a continuous wearing test for several hours and found that the stability and comfort of wearing are very good.

▲In terms of sound quality, the sound quality of several JEET headphones I have used is not bad, and the JEET Air 2 this time is no exception. Overall, I think the low frequency performance of JEET Air 2 is really good. In the expression of “Drum Poem”, the drums are dense, the power is very good, and the low frequency extension is also sufficient.

In the mid-range, the separation of vocal details is relatively clear, and the dental sounds and the sound of swallowing saliva of the female singer in “One I Love” can be distinguished well. The overall vocals are warmer, which is in line with our daily listening song orientation.

The high frequency ductility will be slightly insufficient, especially when listening to a large dynamic sound source. But this pair of headphones is actually used daily, listening to game background sounds, pop music and so on. There won’t be too much demand for classical music listening, so I don’t think there is a big problem with the lack of high frequencies.

4. Summary

The JEET Air 2 bluetooth headset itself has many highlights, such as ultra-small size, ultra-light weight, and support for bluetooth 5.2 and stereo effects. In terms of sound quality, the performance is consistently stable, and at the same time, because the price is less than 300 RMB, it also maintains an excellent price-performance ratio.
