Oppo announced the Enco X2 TWS earbuds back in February. The earbuds supported Wireless and Reverse charging. Now the company has launched a wired charging edition of the same earbuds at a lower price. The new wired charging Oppo Enco X2 earbuds come with multi-level noise cancellation, a dual-driver setup, and up to 40hr of Playtime.

The Oppo Enco X2 wired charging earbuds are launched at a price of 799 Yuan ($119) which is 100 Yuan cheaper than the wireless charging version launched earlier. However, the functionalities and features are almost the same, let’s take a look at it.

Oppo Enco X2 wired charging earbuds Specs & Features

The earbuds come with a dual driver setup with an 11mm dynamic driver paired with a 6 mm planar diaphragm driver. The Enco X2 earbuds are jointly developed by Oppo and Dynaudio and have been specially tuned by musical director Joe Hisaishi. The earbuds adopt the new LHDC4.0 technology and have obtained the Hi-Res Audio Wireless Gold Standard certification.

Each earbud has two built-in noise-cancellation microphones and is also equipped with a triple-core noise-cancellation chip with a 50% increase in computing power. The effective noise reduction bandwidth point can reach up to 4kHz. The earbuds come with IP54 water and dust resistance certification and weigh 56.4 grams.

The Oppo earbuds are said to take around 1 hour to charge completely, while the charging case is claimed to take 90 minutes for a full charge. Interestingly, The Enco X2 can provide up to 2 hours of playtime with just 5 minutes of charge time. It can be charged through its USB Type-C port.

For connectivity, the Enco X2 uses Bluetooth 5.2 with LHDC 4.0 transmission protocol which enables it to support a code rate of up to 900kbps. It also comes with support for the usual AAC and SBC audio codecs. For more information you can read our detailed review of Oppo Enco X2 (Wireless Charging).

Over the past few years, OPPO has taken the lead in the industry with its VOOC fast charging technology. Today marks an important achievement for the company. OPPO has officially announced 125W Flash Charging technology for its smartphones, evolved from its 65W SuperVOOC technology announced last year. This makes it the world’s fastest wired charging technology in the industry. But the company doesn’t stop here, it has also announced the World’s Fastest Wireless Charging technology – the 65W AirVOOC.

125W Flash Charge comes with double-6C cells

OPPO’s new flash charging technology can charge a 4000mAh battery up to 41% in just 5 minutes and 100% in 20 minutes!

The 125W flash charging technology is built on the existing 65W SuperVOOC 2.0 charging protocol. The VOOC charging protocol has always focused on increasing the current (instead of the voltage) to increase the total wattage. The 65W SuperVOOC 2.0 supported up to 10V / 6.5A. But now, with the 125W Flash Charge technology, OPPO has doubled the voltage with the current remaining more or less the same.

In order to achieve an incredible 125W, the OPPO Flash Charge increases the voltage to 20V while the maximum current drops a little to 6.25A. This is further made possible by significantly improving power density properties. Instead of two 3C cells found on the SuperVOOC 2.0 tech, the new Flash Charge protocol utilizes two 6C cells. This marks a breakthrough in the battery ratio (this ratio is defined as the charge and discharge ratio of the cell). The new technology further comes with industry-leading multiple battery tab structures, three parallel charge pumps, and an integrated MCU (Microcontroller unit) for improving charging efficiency.

The 125W flash charge technology is compatible with the previous versions like SuperVOOC and VOOC protocols. It even supports mainstream charging technologies like 65W PD (Power Delivery) and 125W PPS (Programmable Power Supply).

Given the extremely high wattage being thrust into the smartphone, OPPO has also worked on its safety protection features by adding 10 more temperature sensors to monitor the charging status. Other safety measures include fuse overvoltage protection, Type-C to Type-C wire as well as 128-bit high-strength encryption algorithm.

65W AirVOOC Wireless Charging makes Wired Charging Obsolete

In a surprise announcement, OPPO also announced the world’s fastest wireless charging technology. The new wireless charging protocol can fully charge a 4000mAh battery in just 30 minutes! This makes it faster than most current wired charging solutions in the market and has the potential to make wired charging obsolete.

Today we’re not just announcing one flash charge innovation breakthrough.

In fact, in a graph, OPPO revealed that the 65W AirVOOC charges a phone in the same time as its 65W SuperVOOC 2.0 wired charging technology.

The OPPO AirVOOC 65W wireless charging technology uses a self-developed isolated charging pump technology and parallel dual-coil design to improve the wireless charging efficiency. It has also reduced the interference in the charging frequency and comes with five-fold safety protection measures in addition to the standard foreign object detection feature. Like its 40W wireless charging tech, the 65W AirVOOC charging is compatible with the Qi standard.

OPPO also revealed a conceptual wireless charger based on its 65W AirVOOC wireless flash charging technology. The charger comes with a sculpted-glass body which is made of moldless rapid prototyping technology. OPPO reveals that this is the first application of this type of technology in the consumer electronics market.

At the bottom of the charger, there’s a semiconductor cooler for better heat management. This allows the temperature of the phone to be 2°C lower than using a traditional fan for heat dissipation.

Unfortunately, we have no word on the release date or pricing of this 65W AirVOOC wireless charger. We also don’t know when we’ll see a smartphone with this 125W Flash Charge technology.

Nevertheless, this is a big leap in smartphone charging technology. And it’s becoming evident that charging a smartphone won’t be a pain point for users in the near future.

The Pixel 4 and Pixel 4 XL are already shipping to owners and more details are surfacing about the device. Some of these details are interesting while others may be considered as not so important to the average consumer.

Of those important to the average consumer is charging, and according to new info, the new Pixel phones support more than 10W wireless charging. Actually, they support up to 15W wireless charging according to one of the tweets below.

According to the Wireless Power Consortium, the Pixel 4 and Pixel 4 XL have a maximum received power of 11W. The info was shared on Twitter by Mishaal Rahman. However, one of the comments under the tweet by @Coloradowise said Google Support confirmed to him that the device supports up to 15W wirelessly.

Google support confirmed to me last night that it would support up to 15w wirelessly. Is this 11w limit from the handset or the charger?

— Christopher Wise (@Coloradowise) October 22, 2019

It turns out that the Maximum Received Power stated by the Wireless Power Consortium can be higher. Take for example the Maximum Received Power of the Huawei Mate 30 Pro 5G which is stated as 5W but we know the device actually supports 27W wireless fast charging.

It is surprising why Google omitted this very important info at the launch event. They also didn’t announce a new Pixel Stand, and the current one supports only 10W. So if you have a wireless charger that supports 15W or higher, you may want to give it a try.

With wireless charging out of the way, let’s return to wired charging which most people use.

The Pixel 4 and Pixel 4 XL ship with an 18W charger but it actually supports 20W wired charging too. Oh! This applies to the Pixel 3 too. All you have to do is get a USB Power Delivery charger that supports 20W or more. The Pixel 3 supporting 20W wired charging was reported as far back as February but a lot of folks may not be aware.
