Front side (image = left) and back side (image = right) of the individual packaging box When the top lid of the individual packaging box is opened, the inner box containing the charging case is removed. On the right is the inner box containing the quick start guide and safety guide. The description of the individual packaging box is all in English, including the main features on the back and product specifications. The product model number is ETI71 for earphones and ETI72 for charging case. The top lid of the individual packaging box is a pull-up type, and when you take out the inner box inside, the inner box containing the earpiece and the USB Type-C cable appears at the bottom. All of the included items are properly stored, but I felt that it was difficult to take them out because the inner box was the right size. All contents In addition to the earphone body, ・ Charging case ・ Earpiece (S / M / L: M size is already attached to the body) ・ USB Type-C cable ・ Quick start guide (instruction manual) ・ Safety guide Accessories are included. The Quick Start Guide is a 61-page booklet written in 15 languages, including Japanese. The quality of the paper inside is nice to the touch, but I was worried that the back side was very thin and transparent, probably because of the thickness. Japanese page of Quick Start Guide (1st page) Japanese page of Quick Start Guide (2nd and 3rd pages) Japanese page of Quick Start Guide (4th page) Japanese notation is 4 pages in total. Name of each part ・ Bundled items ・ Connect (Bluetooth pairing) ・ Automatic reconnection ・ Pairing with other devices ・ Wear detection ・ Select earpiece ・ Charge ・ Operate ・ Take a picture with remote shutter ・ Noise cancel Ring / Earphone function-Reset to default settings-Specifications Explanations are provided for these 14 items. The booklet is not small, but the font size is not large. Some people may find it difficult to see, especially because the annotation text is small. Japanese page of the safety guide (1st page) Japanese page of the safety guide (2nd and 3rd pages) The safety guide has 41 pages in total and supports 15 languages ​​including Japanese, like the quick start guide. .. The Japanese notation is all three pages: ・ Safety guide ・ Impact on electronic devices ・ Medical devices ・ Hearing protection ・ Traffic safety ・ Children's safety ・ Accessory requirements ・ Battery safety ・ Operating environment ・ Maintenance Information / Warranty Policy on Maintenance / Warning / Environmental Protection / High Frequency Exposure (Koushu Habakuro) Safety-related content and precautions are described over these 14 items. When I put the charging case on my palm, I will check the charging case and earphones from here. First, we will explain the appearance and specifications of the charging case, as well as the pairing method. Charging case Front Charging case Back Hinge part on the right side facing the front Function button USB Type-C charging port USB Type-C Charging port Connecting the USB Type-C cable to charge The characteristic shape of the charging case is It has a glossy and smooth texture. One LED lamp (indicator) is mounted on the front. It's hard to notice, but there is an "OPPO" logo on the hinge part on the back. There is a function button on the right side when facing the front, but this is also familiar to the design and I did not notice at first. A USB Type-C terminal for charging is mounted on the lower side. The LED lamp (indicator) indicates the remaining battery level. When you put the earphone in the charging case, the remaining battery level of the earphone is displayed, and when you remove the earphone from the charging case, the remaining battery level of the charging case is displayed. -Red ... Only a few left-Yellow ... About half-Green ... Charging completed Since wireless charging is not supported, the only charging method is the USB Type-C cable. When the lid is opened with the earphones set When the lid is opened with the earphones removed Inside the lid The inside of the charging case body is quite difficult to see, but inside the lid is the product model number, battery specifications, Japanese techniques Appropriate marks etc. are described. There are no other notations or buttons on the inside, and it is a simple design. Although the earphones were stored in the charging case from the beginning, there is no protective sheet attached to the charging contact part of the earphones, so it can be used immediately. When using for the first time, open the lid of the charging case with the earphones set in the charging case. Then, the pairing mode is automatically activated, so you can pair by selecting "OPPO Enco Free 2" on a Bluetooth compatible device such as a smartphone (smartphone), computer (PC), or music player. "Add device" screen of Bluetooth setting of Windows 10 Bluetooth setting screen of Android smartphone (MIUI 12 of Xiaomi) On a Windows PC, "Settings" → "Devices" → "Bluetooth and other devices" → "Bluetooth or other devices" Select "Add device"-> "Bluetooth mouse, keyboard, pen, audio, or other type of Bluetooth device" and click (tap) when "OPPO Enco Free 2" is displayed. Select "Connect" on the next screen, and if you can connect normally, click (tap) "Finish" to complete the pair setting. For Android smartphones, just go to the Bluetooth item from "Settings" and tap "OPPO Enco Free 2" displayed on available devices to set up a pair. OPPO smartphone (ColorOS 11) Bluetooth setting screen When pairing with OPPO smartphone "OPPO Reno3 A (model number: A002OP)", a visually easy-to-understand display appears, tap "Connect", and then on the side of the charging case. Press and hold the function button for 2 seconds, switch the smartphone screen and tap the displayed "Pair" to complete the pairing. Once you have completed pairing with a device, to activate pairing mode next time: -Disconnect all devices that have already been paired-Put both earphones in the charging case and open the lid. Press and hold the function button on the charging case for 2 seconds. Either of these methods activates the pairing mode and sets the pair with another device. To reset the earphones to the initial state, ・ Put both earphones in the charging case ・ Open the lid of the charging case ・ Press and hold the function button of the charging case for 15 seconds ・ The LED lamp (indicator) of the charging case is Blinks red 3 times This procedure completes the reset. The outside of the earphone The inside of the earphone The contact for charging and the "L" and "R" notation on the bottom of the earphone The product model number is written on the inside of the earphone The back part of the earphone is the touch control area. Slide operation is also possible When the earphone is placed on the palm, the earphone is equipped with a 10mm dynamic driver (speaker), the playback frequency band is 20Hz to 20kHz, the Bluetooth version is 5.2, and the compatible codecs are AAC and SBC. If you look closely, the outer part with vertical lines is the touch control area, and you can perform touch operation and slide operation. The touch operation responds to the extent that you touch it gently even if you tap it lightly, and the slide operation also responds if you lightly trace the back part. The impression is that both touch and slide are responsive. The touch operation in the default (initial value) state is as follows.・ Tap once on both left and right ... None ・ Tap twice on both left and right ... Song forward ・ Tap three times on both left and right ... Voice assistant ・ Press and hold both left and right ... Noise canceling, switching between external sound capture ・ Slide control on both left and right ... Volume adjustment , Enco Free2 is equipped with a "detachment detection function". If you remove the earphones on either the left or right side, the music being played will be paused, and if you put it back on, it will play. For slide operation, slide the back of the earphone up to increase the volume, and slide it down to decrease the volume. As mentioned above, it was responsive and intuitive, so I felt it was quite comfortable. Changes to various touch operations and slide operations will be described later. The slide operation is intuitive and easy to understand. The sound quality is more balanced than the bass of "OPPO Enco Buds (model number ETI81)" (hereinafter referred to as "Enco Buds") reviewed earlier. Of course, the bass sounds well, but it's not as emphasized as Enco Buds. In addition, Enco Free 2 is equipped with a function that optimizes sound quality based on the results of hearing tests conducted with apps, etc., in addition to voice tuning in collaboration with the high-end speaker brand "DYNAUDIO". ing. The volume itself is set to a high level like the Enco Buds, but the sound quality is clearly different from the Enco Buds. If you try Active Noise Canceling (ANC), which cuts ambient noise by up to 42 dB, in a silent state, you can get an immersive feeling at a level that you can understand quite well. On the other hand, if you switch to transparent (external sound capture) mode, you can hear the surrounding sounds well. It also uses a triple microphone noise canceling function during calls and a unique algorithm that reduces wind noise, enabling it to deliver a clear voice to the other party during a call. In addition, it also supports "game mode" that reduces sound deviation with low delay, earphone fit test, and IP54 waterproof and dustproof performance. The built-in lithium-ion battery has a capacity of 41mAh for earphones and 480mAh for the charging case. Playable time is up to 4 hours with earphones alone and up to 20 hours with charging case when noise canceling is ON at 50% volume, up to 6.5 hours with earphones alone and up to 6.5 hours with noise canceling OFF. Can be used for a long time of 30 hours. The "HeyMelody" app Enco Free2 distributed on the Google Play store is compatible with the dedicated app "HeyMelody", including firmware updates and touch operation customization, noise canceling settings, sound quality optimization, and earphones. You can do fit tests, etc. Compatible model selection screen (click to enlarge) Top screen (click to enlarge) After downloading and installing the app, select "OPPO Enco Free 2" on the compatible model selection screen to move to the top screen. Please note that you cannot perform various operations with the app unless your smartphone and Enco Free 2 are connected via Bluetooth in advance. The left is the "Summary" screen, and the others are the "Firmware update" screen. Tap the (i) button at the top right of the screen to move to the "Summary" screen, where you can see the version information of the application. Tap "Firmware Update" on the top screen, and if the update notification is displayed on the transition screen, tap "Update" to update. The first update finished in about 5 minutes, but it's a good idea to run the update when you have some time. The left is the "earphone control" screen, the center and right are the "personalized sound quality optimization" screen From the left, the test completion screen, optimization details screen, and the screen top screen where the test record is saved Tap "Earphone Control" to move to the screen where you can customize various operations of the earphone. It is possible to change to the displayed operation by tapping each item of single tap, double tap, triple tap, long press, slide control. Selectable functions ・ Single tap… None, Play / Pause ・ Double tap… None, Play / Pause, Song back, Song forward / Triple tap… None, Voice assistant activation, Game mode ON / OFF ・ Long press… Noise cancellation is on, noise cancellation is off, one to three can be selected from transparent mode, and the selected mode can be turned ON / OFF. ・ Slide control ... None, volume adjustment, song switching "personalized" In "Optimization of sound quality", put on the earphones and tap "Start". If you hear the sound coming out of the earphones, tap "Yes" and tap "No" to perform the test and create a test record. By doing so, you can optimize the sound quality that suits your hearing. Like the update, it doesn't take much time, but we recommend that you do it when you have time to spare. Also, try to do it in a quiet environment as much as possible. Even after the test is performed, the optimization can be switched ON / OFF. Earphone fit test screen Tap "Earphone fit test" on the top screen to switch the screen display and tap "Play". The sound will be heard from the earphones for a while, so just listen to it and the test will end. From the left, the "Noise Cancellation Settings" area, the "Personalized Noise Cancellation" test start screen, and the post-test optimization screen equalizer selection screen. Scrolling the top screen reveals the "Noise Cancellation" item. Tap the three icons to switch to each mode. Turn on "Personalized noise cancellation" below it, and tap "Start test" on the transition screen to personalize noise cancellation. The test takes only a few seconds, so you can feel free to do it anytime. By tapping "Equalizer" on the top screen, you can select from four types: "Classic", "Dynamic Bus", "Emphasis on Vocals", and "Clear". "Bluetooth" screen (image = left), "paired device" screen (image = right) On a smartphone equipped with OPPO's original user interface (UI) "ColorOS" version 11.0 or later If you have one, tap "OPPO Enco Free2" from the Bluetooth setting screen and tap "Earphone function" to operate the same operations and functions as the HeyMelody app. "Earphone function" screen (click to enlarge) "Earphone control" is at the top of the "Earphone function" screen, and noise cancellation related and equalizer selection, fit test and sound quality optimization are below it. line up. There is even switching ON / OFF of "in-ear detection" (detachment detection function) that was not in the HeyMelody app. By default, it is ON, but if you switch it to OFF here, the earphones will not be paused when you remove them from your ears or play back when you reattach them. The test results of "optimization of personalized sound quality" and "personalized noise cancellation" introduced so far, touch operation, slide operation, in-ear detection settings, etc. are saved on the earphone side. It is not necessary to carry out the test again just because the smartphone to be connected has changed for optimization of sound quality and personalized noise cancellation. Also, regarding "in-ear detection", once you changed the setting to OFF on the OPPO smartphone, it did not work even when connected to another smartphone or PC, so the setting is also saved on the earphone side. Will be there. It may not be used on multiple devices including OPPO smartphones, but this time I tried to verify it on multiple devices, so please refer to it. The best impression is that you can watch with confidence, including not only well-balanced sound quality but also personalized optimization. In addition, it was surprising that the earphones and charging case had a simple design, but in fact they were multifunctional products that were able to reach even the smallest details. And personally, I felt that the volume adjustment by slide control was epoch-making. Combined with the sensitivity of the touch sensor and the shape of the earphones, it is very easy to use and gives a good impression. I felt that it was a product with excellent cost performance overall, so if you have a chance, please give it a try. Shooting cooperation: Aya Yuri Finally, I will introduce the opening video of Enco Free 2 and the video comparing the appearance and bundled items with Enco Buds released on the same day.
