Xiaomi Air 2s TWS VS OPPO Enco W31: Design

Although both the Xiaomi Air 2s TWS and the OPPO Enco W31 have a semi-in-ear design, their overall appearance design is very different.


First of all, the OPPO Enco W31 charging box is a flat, circular design, a bit similar to the HUAWEI FreeBuds 3. And provide white, black, pink 3 kinds of color choice. As for the headset part, OPPO Enco W31 is close to AirPods Pro.

The appearance of the Xiaomi Air 2s TWS is the same as that of the previous Xiaomi Air 2 TWS. It is also a simple and compact rectangular charging box with a physical button on the side of the charging box. The Xiaomi Air 2s TWS headset is similar to AirPods 2. In addition, Xiaomi Air 2s TWS is only available in white.


On the whole, the appearance of Xiaomi Air 2s TWS and OPPO Enco W31 is very simple and stylish, in line with popular aesthetics. But the OPPO Enco W31 may be a little better when it comes to the wearing comfort. Because the OPPO Enco W31 provides S, M, L three different sizes of rubber earplugs, it can fit the auricle more firmly, and it is not easy to fall off without tiredness for a long time.


Xiaomi Air 2s TWS VS OPPO Enco W31: Sound Quality

In terms of sound quality, Xiaomi Mi AirDots Pro 2s supports Bluetooth 5.0, thanks to LHDC HD Bluetooth decoding technology, Xiaomi Air 2s, which can enjoy nearly Hi-Res-level sound quality in the wireless state. The built-in 14.2mm loudspeaker + special large composite diaphragm moving coil ensures the balance of the three frequencies and restores more sound details.


The OPPO Enco W31 TWS also supports Bluetooth 5.0. the headset uses dual TPU composite graphene diaphragm speakers and supports AAC HD audio coding and SBC audio format for higher resolution and restoration of music details.


However, in the actual experience, the sound quality of OPPO Enco W31 lags slightly behind that of Xiaomi Air 2s TWS LHDC. But if your device doesn't support LHDC 3.0, the sound quality of the OPPO Enco W31 is pretty much the same as that of the Xiaomi Air 2s TWS.


Xiaomi Air 2s TWS VS OPPO Enco W31: Noise-cancelling

In terms of noise reduction, the OPPO Enco W31 is equipped with dual-microphone beamforming technology, and each headset is equipped with two high-sensitivity microphones to comprehensively enhance the sound pickup ability. combined with the ENC noise reduction algorithm, the noise, and human voice are intelligently identified and separated, and the windproof noise cavity design is adopted to effectively reduce the impact of wind sound on call quality.


In fact, Xiaomi Air 2s TWS has also improved a lot in noise reduction, also using the popular dual-microphone beamforming technology to comprehensively enhance the sound pick-up ability and isolate a certain amount of ambient noise to effectively improve the call quality.


Xiaomi Air 2s TWS VS OPPO Enco W31: Latency

Ultra-low latency is the biggest highlight of OPPO Enco W31. With the advantage of its own mobile phone manufacturers, OPPO Enco W31 has done targeted software optimization and transmission optimization on the mobile phone module to achieve full-link delay optimization, reduce the sound delay in all links, and achieve the experience of delay as low as 94ms, in which the headset delay is only 47ms. This is very good for users who love mobile games.


As we can see from the previous post on Xiaomi Air 2s vs Xiaomi Air2 TWS, reducing latency is one of the upgrade points of Xiaomi Air 2s TWS. But even so, the latency of the Xiaomi Air 2s TWS is not as good as the OPPO Enco W31 with OPPO smartphone.


Xiaomi Air 2s TWS VS OPPO Enco W31: Battery Life

Battery life is usually an important factor in deciding whether to buy the headset, and there is also a big difference between the Xiaomi Air 2s TWS and the OPPO Enco W31 in terms of batteries.


The OPPO Enco W31 true wireless headset with a charging box can provide up to 15 hours of long battery life and 3 hours of music time per ear.
