From the traditional three-frequency perspective：
Low frequency，Two new sound effects brought by the new firmware are enabled，Will tighten the low frequency sense to increase the depth of the dive，Strengthen the control of ultra-low frequency (below 80Hz) on the basis of default，Powerful bass without sound dye。In comparison, the overall energy sense of "Dynaudio is simple and leisurely" is on the plate，Less low frequency sense，And "Dynaudio warm and gentle" is the opposite。
Vocal aspectThe most significant gain，The new two kinds of sound effects tend to make the image clearer，Just "Dynaudio warm and gentle" vocals are thicker、Warm and soft，Suitable for performing some mature voice singers (such as Tsai Qin's works)，Strong infectiousness；The vocal thickness of "Dynaudio is simple and leisurely" is moderate，More advanced，Tracks suitable for highlighting (such as Faye Wong's works)。
High frequency part，The two sound effects are still emphasized、extend，and imaging clarity。The main difference between the two is that the brightness of "Dynaudio warm and gentle" is slightly lower，Suitable for performing sweet but not harsh treble，More soft；"Dynaudio is simple and leisurely" the opposite，More details，But there is no difference between the two as a whole。
in short，The two newly added sound effects tendencies are very close，Very in line with the taste of Hi-Fi enthusiasts，There are only opposite fine-tuning in some details to give users a variety of choices，Overall, the tuning is much better than the previous version of the firmware.，Especially when paired with a lossless phone that supports LHDC, it can be appreciated，This experience will be more in-depth。
Noise reduction experience and battery life：Two-speed noise reduction can also transmit through
——Noise reduction experience
Due to the lack of professional equipment such as artificial ears，So we have the noise reduction effect provided by OPPO Enco X Blues Edition True Wireless Noise Cancelling Headphones，Still subjective feelings。
Judging from our actual experience，The latest version of the firmware brought by the OPPO Enco X Blues True Wireless Noise Cancelling Headphones should not have made much adjustments in noise reduction.，There are still four modes to choose from：Strong noise reduction、Weak noise reduction、Noise reduction、Transparent mode。
In transparent mode，OPPO Enco X Blues Edition True Wireless Noise Cancelling Headphones are more comprehensive in picking up the sound of the surrounding environment，Especially the details are far stronger than the "noise reduction" state。
You can infer the surrounding sounds heard by users in transparent mode，Must be recorded by the microphone and played through the headset，Therefore, the sound details are very detailed，Suitable for users to listen to music while they are、Use when you need to pay attention to the surrounding situation。
In weak noise reduction mode，Some low-frequency noise will not be completely eliminated，But there is some reservation，Users can vaguely distinguish them。
The noise reduction capability in strong noise reduction mode is higher than that in weak noise reduction，When turned on, the low frequency noise in its supported frequency will be completely eliminated.，The maximum noise reduction depth can be reached by -35dB，Creates a "world is quiet" effect。
It is worthy of recognition，Whether it is weak or strong noise reduction，All ear pressures are at the right level，The feeling of oppression is better controlled。
- battery life
Due to the tight test time，We have no conditions to do the "death test" limit battery life test，Based on previous test results，OPPO Enco X in Strong Noise Reduction Mode，Listen to songs for 30 minutes without interruption，The power of the headphones will drop from 100% to 90%。Can estimate，In powerful noise reduction mode，The single battery life of the headphones is about 5 hours，Basically consistent with the official description。
In addition, use with the charging box，The battery life can be further extended，It reaches about 25 hours。If the noise reduction is always turned on，Battery life will be shortened to about 20 hours。
and，OPPO Enco X supports wireless charging，Put it on a wireless charger at any time to recharge the power，You don't have to worry about battery life when using daily frequency。
Summarize：999CNY noise-cancelling true wireless headphones + Who else can I do with Danna
OPPO Enco X Blues Edition True Wireless Noise Cancelling HeadphonesNot "OPPO Enco X second generation"，It's just a brand new color version，What is a little special is to try out the new firmware first，The first to enjoy two new sound effects upgraded by the ever-evolving Danner tuning。
After many days of experience，We believe that this headset has excellent sound quality first，It is mainly due to its "dual-unit" architecture design using an 11mm dynamic horn and a 6mm flat diaphragm speaker.，The former performs in low- and medium-level，The latter is responsible for high frequency，The combination of the two builds a hardware platform that determines the sound quality performance。
at the same time，LDAC encoding is difficult to apply in many TWS headphone products，AptX series encoding is only available for Qualcomm chips，In the context of using SBC/AAC, a lower quality encoding, has to be used.，This work is the first to respond to LHDC encoding，This is an encoding format with bit rate second only to LDAC，Also possesses Hi-Res Audio Wireless certification，Let the details and levels of sound closer to the original audio performance，And not picky about platform chips，Breaking the sound quality ceiling of TWS devices from the root。
The biggest change brought by this new firmware is the addition of two new sound effects - "Dynaudio simple and leisurely" and "Dynaudio warm and gentle"，From the actual experience, the sounds interpreted by these two sound effects tend to be more Hi- Fi listening experience，The sound field is wider、Permeable，There is a longer extension on both ends of the sound，Enlarge the music details at the same time，More detailed captures from ears、Clearer information，In line with the taste of Hi-Fi enthusiasts，Especially with mobile terminals that support LHDC, which can enjoy it。
In terms of noise reduction，OPPO Enco X Blues Edition True Wireless Noise Cancelling Headphones Show flagship level。No need to have too much ear pressure when achieving noise reduction，It even provides two-speed noise reduction to meet users' different refined noise reduction needs: "silence" and "quiet".。
Among TWS headsets within 1,000 yuan，Whether it is mid-to-high frequency performance or resolution for lossless sound sources，999CNY's OPPO Enco X Blues Edition True Wireless Noise Cancelling Headphones are among the best，It is also a noise reduction TWS with particularly impressive sound quality performance in the Android camp，Worth a taste。
