Sound Related

What should I do if I experience unclear or interrupted calls when using soundcore C40i?

1. Using the earbuds for gaming and calls at the same time can affect call quality. We recommend avoiding this scenario. 2. Some phones with high output power may experience voice distortion or excessive noise during calls if the earbuds' volume is set too high. Please lower the volume to an appropriate level. 3. Switch to a different network or environment to see if the situation improves as call quality can be affected by low network speeds or excessive environmental interference. 4. Outdated versions of your earbuds' firmware, call software, and device operating system can affect call quality. Please update them to the latest version.

What should I do if I find the sound quality of soundcore C40i does not meet my expectations?

1. Adjust the sound effects in the soundcore app to improve sound quality. 2. When the earbuds are connected to a phone, playing music during a call may lead to a decline in sound quality. Audio transmitted via the Hands-Free Profile (HFP) can result in reduced music quality. 3. If the earbuds are connected to a macOS computer and you access the system's input settings page, the earbuds will enter call mode, resulting in reduced music quality. Please close this settings page. If you are using a Windows computer, ensure that the sound output is set to "soundcore C40i." 4. Verify if the song being played has quality issues. For the best experience, try using original versions of songs. 5. When watching videos, check if the video itself has sound quality issues. Try switching to a different video source.

What should I do if I experience unbalanced sound when using soundcore C40i?

1. Ensure the earbuds are worn in the correct orientation. 2. Adjust the position of the earbuds in your ears.

To do so, return them to the charging case and leave the case open. Then, press the button on the case for at least 5 seconds until the LED turns red. The LED will then flash red three times before switching to a rapid white flash, indicating a successful reset.
Operations

How do I connect soundcore C40i Bluetooth earbuds?

1. First Setup: - Remove the protective film from the charging case and power on the earbuds.

What are the two types of Dual Connections?

Type 1 (for other earbuds): With both your phone and computer connected to the earbuds, the earbuds will play audio from whichever device starts playback first without letting the second device cut in. For example, if your computer starts playing music first, the earbuds will continue to play from the computer even if your phone starts playing audio later. Type 2 (for soundcore C40i): With both your phone and computer connected to the earbuds, the earbuds will play audio from the device that starts playback last. For example, if your computer starts playing music first and then your phone starts playing audio, the earbuds will switch to the phone and pause the computer's audio. Note: Due to compatibility issues, notification sounds may be mistaken as audio and can override the playback.

How do I reset soundcore C40i?

Return the earbuds to the charging case and leave the case open. Then, press the button on the case for at least 5 seconds until the LED turns red. The LED will then flash red three times before switching to a rapid white flash, indicating a successful reset.
Bluetooth Connection Related

What should I do if I experience Bluetooth disconnections or sound interruptions when using soundcore C40i?

1. Reduce the connection distance and avoid walls between the earbuds and the device. 2. Switch to a different network or environment to see if the situation improves as call quality can be affected by low network speeds or excessive environmental interference. 3. Outdated versions of your earbuds' firmware and device operating system can affect call quality. Please update them to the latest version. 4. In busy areas, such as high-speed train stations, signal interference, and frequency band congestion may cause stuttering or disconnections, which is common. 5. Reset the earbuds. To do so, return them to the charging case and leave the case open. Then, press the button on the case for at least 5 seconds until the LED turns red. The LED will then flash red three times before switching to a rapid white flash, indicating a successful reset.

What should I do if my soundcore C40i stay connected after being placed in the case?

1. Inspect the charging pins in the case to see if they are recessed. If so, apply a small amount of alcohol and gently poke the pins with a toothpick or tweezers. Once the pins pop out, immediately and thoroughly wipe the area dry. 2. Ensure there is no dirt on the earbuds' pins or the surface of the charging case. If it's dirty, clean the area using alcohol and a cotton swab. 3. Confirm that the ear grips are correctly installed.
Multipoint Related

Why can't I enable Dual Connections while on a call?

The earbuds cannot enter pairing mode during an incoming call or while you're on a call. Please try again after the call ends.

Why do I experience no sound when switching between devices with Dual Connections?

When you pause music on your phone and immediately play audio on your computer, you may notice a period of silence. This occurs because the earbuds need some time to disconnect the A2DP channel from the phone and establish it with the computer. Similarly, if you pause music on your computer and quickly switch back to your smartphone, a short delay may occur. This transition typically takes about 3 to 5 seconds, depending on the devices. To ensure a smooth switch, it's best to wait a few seconds after pausing music on one device before playing audio on the other.

Why doesn't audio automatically switch between devices?

When you pause audio on one device and switch to the other, you will need to manually play the audio. This manual action ensures you maintain full control over your audio sources and helps prevent any confusion or disruption that may arise from automatic switching.
Call issues

What if the sound does not come out of the earbuds after I answer a call on my iPhone?

If you answer the call using the earbud button, your iPhone will automatically set the earbuds as the audio output device. If you answer the call on your phone, the device will use the phone speaker by default. To ensure your iPhone always uses your earbuds for calls, adjust the settings as follows: On your iPhone, go to Settings > Accessibility > Touch > Call Audio Routing, and select Bluetooth Headset.

What should I do if the other party cannot hear me clearly during a call?

1. Ensure that the left and right earbuds are worn in their designated ears. 2. Adjust the wearing angle. Position the speaker close to your ear canal by moving the earbuds toward your earlobe. If it's too far from the ear canal, it may impact sound quality. 3. Ensure no foreign objects obstruct the microphone.

What should I do if the other party cannot hear me during a call?

1. Check the Microphone Status: Ensure that the microphone of your soundcore C40i is not muted. Make sure that the call software is not muted either. 2. Check the Input Settings of the Call Software: Use the input call detection feature in the software to verify that the settings are correct and that the device or call software can access the earbud microphone properly. Restart the call if needed. 3. For Windows Users (Win 10): - In Settings, search for "Turn on or off mono audio." - Go to Change Other Sound Settings > Playback. - Disable Stereo mode and enable Hands-Free mode for optimal audio performance. Explanation of Modes: Stereo Mode: In this mode, the device typically does not support microphone usage. It provides better sound quality because it supports high-quality stereo transmission. Hands-Free Mode: In this mode, the device supports microphone usage, allowing users to make voice calls and play audio simultaneously. However, the sound quality is generally lower.
Battery Related

Why does the actual battery life differ from the advertised one?

The advertised battery life is derived from tests conducted in a controlled laboratory environment. During these tests, the device is set to 50% volume and uses the soundcore's signature sound effect. The device then continuously plays a specified set of music tracks. By standardizing these conditions, we can ensure that the battery life measurement is consistent and reliable. However, please note that actual battery life may vary due to factors such as volume levels, audio content, and usage patterns.

How can I maintain battery health and longevity?

Over time, the battery health of electronic devices declines, leading to shorter battery life. To slow the decline, avoid letting the battery level drop to 20% or lower before recharging. Frequent depletion to such low levels can strain the battery and accelerate wear. Instead, recharge when the battery is moderately low. Additionally, avoid completely discharging the battery until the device shuts down. This deep discharge can harm the battery's longevity. For devices like wireless earbuds and their charging cases, we recommend charging them at least once a month, even if not in regular use. This helps prevent over-discharge which can significantly impair battery performance and lifespan.

Why does my soundcore C40i's battery life differ from the advertised claims?

1. One of the most significant factors affecting battery life is the volume level. Higher volumes lead to increased power consumption. 2. The type of audio you play also plays a crucial role. Different music genres and content affect battery life differently. For instance, soundtracks with heavy bass and intricate soundscapes require more power for accurate playback.
Charging Related

What should I do if my soundcore C40i won't charge?

1. Check for Debris: Ensure that the case's charging port and the charging cable's terminals are clean and free of any debris. Dirt or foreign particles can obstruct the connection and prevent charging. 2. Try a Different Charging Cable: If cleaning doesn't help, try a different charging cable. We recommend using the original cable that came with the product. If you are in fact using the original cable when the issue occurs, try a third-party cable. 3. Verify Charging Head Output: Sometimes, the charging adapter may not provide sufficient current. Check the output current of your charging adapter and make sure it matches or exceeds the input current specified on the charging case (5V/0.5A). 4. Inspect Charging Case Pins: Examine the pins inside the charging case. If you notice any debris or dirt, clean it promptly. 5. Check for Pin Misalignment: Ensure that the pins in the charging case are not recessed or misaligned. If the pins are recessed, apply a small amount of alcohol and gently poke the pins with a toothpick or tweezers. Once the pins pop out, wipe the area dry and the earbuds should function normally. 6. Clean Earbud Pins: Inspect the pins on the earbuds. If they appear dirty, clean them with alcohol to remove any grime or residue.
App Related

What should I do if I cannot enter the soundcore app?

1. When the earbuds are connected to two devices, you can only access the soundcore app on one of them. Please check if the app is open on both devices. If so, fully close it on one of the devices and try again. 2. If you're using an iOS phone, please check if you're attempting to open the app during a call. The app cannot be entered during a call, so please try again after the call has ended.

What should I do if I cannot find "soundcore C40i" in the soundcore app?

Download the soundcore app from Google Play Store (Andriod) or App Store (iOS), enter the app, click on "Add Devices" on the main page, click on the earbud icon, and finally, click on "soundcore C40i" to connect.
Waterproof Related

What is the waterproof rating of soundcore C40i?

1. soundcore C40i has an IPX4 water resistance rating, meaning it can withstand light sweat and slight rain, making it suitable for exercise. However, IPX4 does not protect against submersion in water. Higher ratings like IPX7 or IPX8 are needed for such protection. To prevent damage, avoid activities that cause excessive sweating while using the earbuds. 2. After exercise, if moisture or sweat is present on the earbuds, clean them before returning them to the charging case.

Very disappointed DO NOT BUY

I have never been so disappointed in a product from Soundcore. These are not worth the price. Why do the speaker holes point away from the ear? Why don't custom control settings work at all? Why is the volume so low? I have purchased $30 open ear buds from Ali Express that are better than these. Don't believe the paid reviews you see on Youtube. These are not good and not worth the price. Avoid this product.

Comparison of these clip-ons to my beloved in-ear buds

With a recent ear injury, I can't wear my regular in-ear buds for runs or work for a while. These clip-ons have been fantastic; they've brought back the joy of music and podcasts that I didn't fully realize how much I had been missing.I had assumed that all clip-ons would sacrifice volume and audio quality and risk being heard by people nearby, but the sound quality on these Anker Soundcore clip-ons is surprisingly good, and the volume can go way higher than I need (or even want). I had a friend put her ear next to mine and tell me when she could hear sound leaking, and she heard nothing until I raised the volume beyond what I would ever listen at, so all's good there too.The mics on my other earbuds do a significantly better job at clearly transmitting my voice on phone calls, but these are still usable. We recorded a test call so I could hear it, and it sounded like when someone's conference-call software is over-aggressively reducing noise and clipping too much voice frequency.The comfort surprised me. These buds are lightweight and ergonomic enough that I hardly feel them on my ears when I'm listening. It's only when they're on my ears but I'm not actively using them that I really notice them hugging my helix. The default ear grips are the right size for me and aren't at all tight or squeezy. They just rest there lightly.I absolutely love that the app lets me customize what the tap commands. On my other buds, the commands aren't intuitive to me, but these are easy to remember since I set them. And button-pressing is more comfortable on these clip-ons compared to my in-ear buds, where every press requires putting pressure against the inside of my ear. (My favorite are the "tap" style that might be capacitive or something, so no pressure is involved, but neither these nor my other buds have that.)The build-quality doesn't *feel* as solid as on my other pair. These buds feel plasticky, as does the case. But that impression is only while in hand, not while on ear. Also, that impression goes the other way once I open the case: inside are magnets that pull the buds perfectly into charging position but also release the buds at what feels like just the right amount of force, like in a tactilely satisfying way.Bluetooth pairing was a breeze, and charging is straightforward, with a bright status LED on the case. My other set is older (but fancier) and has pin-hole LEDs that are hard to see.These are IPX4 water resistant, so working out with them ought to be fine, but I wouldn't take them running like I do with my other buds, which are fully waterproof and can handle pooling sweat (it's *hot* where I live) then accompany me for a swim. I'm also not sure how well these would stay on during a road run. I gave them a few skips of a jump rope, and they didn't fall off but started to feel like they could. I don't hold this against them, because they seem like they weren't designed for sports (or marketed for it) like my other ones, and these are very good for the price range they're in. But I do miss those features.These have been great ear buds, and I expect I'll continue using them even after my ear gets fixed and heals (may it hurry up though!) because the quality is really good and I find them comfy and even kinda cute.

I like them

I have TMJ and these are great! In ear pods usually move around a lot due to my TMJ and cause the sound to pause or disconnect when on the phone or listening to music. Also I can hear everything around me and also hear my music or my call.No more calling out huh or are you talking to me? lolWhat I don’t like is the hard plastic ear pieces so they fit my very tiny ears. I have the large ones on so it doesn’t slip around. I do wish there was a silicone option because on my tiny ears these things look bulky.I also don’t like that there are no options for cases available yet AND I cannot track these.

Very good audio, innovative and very comfortable open-ear design.

The Soundcore C40i by Anker is an earbud set with an open-ear design. The earbuds get attached onto the earlobes with an 'U' shape design.The earbuds come in a hard case and each one of them have a multifunction single button that serves as Bluetooth pairing, answer and hang calls, volume controls and also previous and next track selection.The Soundcore C40i by Anker are as light as feathers and they are the only earbuds I can use the entire day without noticing I have them on me. They go onto the thinnest part of the lobe and they conformed to it securely, even on vigorous movements. They come with extra attachments in case you need a tighter fit, but I did not need them.The sound quality of these earphones is very good, and the Souncore app allows for more audio and controls customizations. The audio includes features such as adding a bit of extra bass, 3D Surround sound, EQ or volume booster. Only one sound effect could be selected at a time. The app also allows to customize the left and right buttons to your liking. Although the app is not necessary for basic functionality, it could also be use to upgrade the firmware of the earbuds.I like the physical buttons, but I did notice a bit of a lag by the earbuds to respond to the touch of the control buttons. It could take a second for the earbuds to respond after pressing the buttons, whether to pause music, increase volume or select the next audio track. Maybe Anker could fix it with a firmware update.The Soundcore C40i have a remarkable blend of unique design, very good audio quality, and all-day comfort. I do like that these earbuds are simple to use and leave your ears open to hear everything around you.

Each are conveniently labeled either ‘L’ or ‘R’.CONS - The charging cord is very short. The product does not come with a charging block, just the cord.OVERALL - These are a great alternative to bulky headphones with clear sound and are easy to use.Thank you for reading my review!
