What needs to be admitted is，Among the true wireless Bluetooth headsets，Apple AirPods' product strength、All have the best influence，But its closed iOS ecosystem，To a large extent, it limits the choice of Android users，Only suitable for Apple users，And the high price is also a bit distressing for the wallet。So are there any suitable choices among the 100-yuan-level headphones with a low entry threshold?
2021May 6, 2019，OPPO is inK9 series super-dimensional launch conferenceThe OPPO Enco Air True Wireless Headphones released on the page are actually more in line with the needs of relevant users，The most obvious thing about this work is that its appearance design is very obvious - the rare translucent jelly bin design and fresh color matching are eye-catching.，Almost no opponent in recognition。

The headphones can support independently for 4 hours (with a charging case up to 24 hours) and "charge for 10 minutes，The super battery life and fast charging of 8 hours of listening to songs are the special highlights of "no one can have it"，Can be regarded as the same price benchmark。next，It is our detailed review experience of OPPO Enco Air True Wireless Headphones。
OPPO Enco Air True Wireless Headphones adopt the round shape of the Enco series TWS headphone charging chamber，Frosted textured shell with a fuller arc design。The translucent jelly bin on the top cover of the headphone box is the finishing touch of the whole box，Such a clean and transparent visual effect has a cool feeling。Color selection，OPPO Enco Air True Wireless Headphones are released and announced as "white"、Dare to "blame"、"Blue"、A little "blue" four colors，Whether it is the selection or color naming，All are quite youthful。
The host of OPPO Enco Air True Wireless Headphones adopts a semi-in-ear design，Easy to get the ear handle，The weight of a single ear is only 3.75g，Small and round。You can see that the ear canal structure of OPPO Enco Air true wireless earphones has a relatively obvious design sense，It can be felt that it fits the ear contours in actual wear，While ensuring comfort，Make the headphones stable。
Interactive experience：OPPO's mobile phone is still friendly when it opens the cover.
As a TWS headset，The first step to get it is naturally to connect wirelessly with your phone。How is the connection experience? TWS feature settings、Is firmware update troublesome? These issues are worth paying attention to。
In terms of connection interaction，OPPO Enco Air True Wireless Headphones are the most convenient to use with OPPO's own mobile phone，Open the cover to identify without manual Bluetooth pairing、Open cover connection。OPPO's mobile phone system settings also integrate headphone setting options，Users can adjust gesture control here、Firmware upgrade。
and，OPPO is not closed。At the beginning of the year, OPPO Watch's health app was opened to third parties，Now in the field of acoustics，OPPO launches an APP called "Huanlu"，To ensure that third-party equipment uses OPPO Enco Air true wireless headphones and other acoustic products，Able to have a complete software experience and support services。
It is worth mentioning that，By default, you can use OPPO Enco Air true wireless headset to answer calls through simple touch operation.、Cut song、Various interactive gameplay such as volume adjustment：

It is worth mentioning that，After leaving the storage box，Headphones that have not played for a long time will enter low power mode，To save power。
Sound quality experience
Sound quality is sometimes a metaphysical thing。The frequency range that people with normal hearing can perceive is approximately 16~20,000Hz，After 25 years old, the sensitivity to frequencies above 15,000Hz is significantly reduced，When the frequency is higher than 15000Hz，Hearing moves downward，And as you age，The upper limit of frequency perception has been decreasing year by year，Cochlear hair cells are getting fewer and fewer。What I think is very simple to have a good sound quality – a good speaker and a good sound source，It will indeed be different。
OPPO Enco Air True Wireless Headphones are not criticized in this regard，It provides a 12 mm composite titanium diaphragm dynamic coil unit。The rigidity provided by PEN titanium plating material of the diaphragm ball can effectively suppress segmentation vibration、Improve transient response，Bring bright and clear medium and high frequency listening experience，As for the edge of the diaphragm, the PU material is used，Lightweight、Strong toughness makes it easier to push。
This will not only bring about a larger low-frequency dynamic range，It also makes the sound transition more smooth and natural，Make the low frequency performance of OPPO Enco Air True Wireless Headphones strong and powerful，Medium and high frequency is clearer and brighter。
How is the sound quality，After all, we need to test the performance of the three-frequency，Everyone may feel different about the three-band，What I am talking about here is my own feelings。Listen to "California Hotel" to experience the low-frequency performance，OPPO Enco Air True Wireless Headphones Bass Without Banging，Keep a certain dive thick，Click to stop；"Just Like Your Gentleness" is a song used to feel the vocals。OPPO Enco Air True Wireless Headphones are more outstanding in vocal performance，Clear and powerful；"The Moving Three-pointer" is more rock-speaking，Except for the voice、Outside the harmony，There are a lot of percussion and electronic elements，The high frequency of some paragraphs is more complicated，Test the high-frequency resolution of headphones。
It is worth mentioning that，As a manufacturer who has been deeply engaged in the field of acoustics for 16 years，OPPO Enco Air True Wireless Headphones also received the tuning of the Blu-ray team，The high frequency and mid frequency performance of this headphone are quite good，It's just that the potential tension in some paragraphs is still not enough，But it's enough for a headset worth 299 yuan，High and mid-frequency are still better parts。
As for audio format，OPPO Enco Air True Wireless Headsets Support AAC High Definition Audio Codec and SBC Audio Format，Among the headphones of the same price, it is in normal range。
Delay experience
Compared to wired headphones，Delay has always been the eternal shortcoming of TWS headphones。Although listening to music and watching dramas in daily life may not have much impact，But when the game is，The disadvantages of high delay will appear。
For this，OPPO Enco Air True Wireless Headphones are more stable in connection、Bluetooth 5.2 chip with stronger anti-interference，10Achieving stable connections within the meter range。Generally speaking，The sound delay of wireless headphones consists of three parts：Mobile、Game side、Headphone end，To minimize the delay of TWS headsets, it is impossible to bypass these three ends。
for games，OPPO has carried out system-level low-latency optimization for mobile phones and headphones。When playing mainstream mobile games such as Peace Elite，It will automatically enter low-latency mode，Optimize the delay in processing game audio。As for the headphone side，OPPO Enco Air True Wireless Headphones are equipped with Bluetooth 5.2 chip，It also reduces the number of Bluetooth retransmissions through binaural simultaneous transmission to reduce the sound transmission delay。
According to OPPO，OPPO Enco Air True Wireless Headphones with OPPO Mobile，The maximum delay of the full link can be as low as 94 ms。This seems to have achieved the lowest connection delay level of TWS headphones of the same level on the market，The author actually tests that it is no problem to use it to play "Peace Elite"，The delay in gunfire is almost impossible to feel。
Fast charge and battery life：Charge for 10 minutes and listen to songs for 8 hours
battery life，The following data is provided for reference：
OPPO Enco Air True Wireless Headphones Independent Music Endurance can reach 4 hours，Recharge the charge at any time with a charging box，Provides up to 24 hours of musical life。The battery life of the headset is 2.5 hours，With a charging case, it can provide up to 15 hours of call life。
Moreover, OPPO Enco Air true wireless headphones also support headphones + charging box dual fast charging，10It can be charged in minutes and enough to listen to songs for 8 hours，The headphones can be fully charged in just about an hour。
Here we have a brief test，The relevant test results can basically confirm the official statement。
OPPO Enco Air True Wireless Headphones at about 40% of the volume，Connect to OPPO Find X3 Pro to continuously play music，Achieve more than 5 hours of battery life，Compared with the official data, it is even higher。
Summarize
It is worth mentioning that，OPPO Enco Air True Wireless Headphones have also passed TÜV Rheinland's TWS Headphones High Performance Certification，Fully proven its interoperability、Delay、stability、Excellent performance in test dimensions related to user experience, such as call clarity, and other tests。
Design aspects，OPPO Enco Air true wireless earphones not only follow the sleek shape of the Enco series TWS earphone charging compartment，On the basis of it, a new pattern of translucent jelly bins is played，Pull the recognition level。In addition, the semi-in-ear design of OPPO Enco Air true wireless headphones will not cause too obvious intrusion to the ears.，And easy to get the ear handle。

Battery life and fast charging are a highlight of OPPO Enco Air true wireless headphones，Independent music battery life can reach 4 hours，Recharge the charge at any time with a charging box，Provides up to 24 hours of musical life。The battery life of the headset is 2.5 hours，With a charging case, it can provide up to 15 hours of call life。10It can be charged in minutes and enough to listen to songs for 8 hours，The headphones can be fully charged in just about an hour。
Looking at the current true wireless headphone market，The main ideas of products of different manufacturers are different。Can design、sound quality、interact、Battery life, etc.，There are very few products that have reached a relatively balanced balance，OPPO Enco Free happens to be such a balanced work。If active noise reduction is not your urgent need，That's based on the price of 299CNY，OPPO Enco Air True Wireless Headphones are definitely worth considering。
