Why wireless headphones became quieter on Android and how to fix it

You are used to a comfortable volume in your favorite Sony WH-1000XM5 or AirPods Pro, but suddenly you noticed that the sound became muffled - as if someone turned the control down by 30%? This problem appeared en masse among Android users in 2023–2026, and its reasons lie not only in the smartphone settings. The culprits may be both hardware limitations (for example, a new standard) and software updates from Google aimed at protecting hearing. Bluetooth LE Audio), as well as software updates from Google aimed at protecting your hearing.

In this article we will look at why wireless headphones have become quieter on Android - from hidden sound profile settings to forced volume limits in the EU region. You will also find step-by-step guide for diagnosing and restoring the previous sound level, including rare techniques such as resetting 7 key reasonsWhy wireless headphones have become quieter on Android - from hidden sound profile settings to forced volume limits in the EU region. You'll also find step-by-step guide for diagnosing and restoring audio levels, including rare tricks like resetting Bluetooth MAC-address or rolling back the headphone firmware. We will pay special attention to the model Nothing Ear (2) and devices on chip Qualcomm WSA8835 —their owners encounter the problem more often than others.

Before moving on to solutions, check the basic points: whether the “Silent” mode is activated on the smartphone, whether the transparency (Transparency Mode) or noise reduction (ANC), which can artificially reduce the volume. If everything is in order, read on.

1. Update of Bluetooth LE Audio and LC3 codecs With the release of newer versions, Google is actively promoting the standard, which replaced the classic one. The new protocol promises better sound quality with less power consumption, but it has a side effect: many users note

With the exit Android 13 and newer versions Google is actively promoting the standard Bluetooth LE Audio, which replaced the classic A2DP. The new protocol promises better sound quality with less power consumption, but it has a side effect: many users report reduced maximum volume a 20-40% decrease when connecting headphones.

The reason lies in the codec LC3 (Low Complexity Communication Codec), which is the default in LE Audio. This codec is optimized for energy efficiency, but does not always handle the dynamic range of audio correctly. As a result:

• 🔊 The bass becomes less saturated (especially noticeable on tracks with frequencies below 80 Hz).
• 🎵 The overall volume level decreases, even if the smartphone is set to maximum.
• 🔋 Sound delay (latency) noticeably increases when watching a video.

How to check if LE Audio is used on your device:

1. Open Settings → Connected devices → Headphones → Settings (gear).
2. Look at the "Audio Codec" section. If it says LC3 or LE Audio the problem is confirmed.

⚠️ Attention: On some devices (for example Samsung Galaxy S23 with One UI 6.0), forcibly disabling LE Audio may result in an unstable headphone connection. Before experiments, create a backup copy of your Bluetooth settings.

2. Volume limit according to the EU Volume Cap standard

Since 2023, manufacturers of smartphones and headphones sold in the European Union are required to comply with the standard EU Volume Cap (EN 50332-3). This regulation limits the maximum volume of devices to 85 dB to protect your hearing. However, many users outside the EU also encounter forced sound reduction - why?

The fact is that some brands (for example Xiaomi, Oppo, Realme) release global firmware with the limitation activated by default, regardless of the region of sale. Signs of EU Volume Cap:

• 📉 The volume drops sharply after 70–80% of the scale on the smartphone.
• 🔕 A warning appears in the sound settings: “The maximum volume is limited for your safety.”
• 🎧 Headphones of different brands sound quieter on the same smartphone.

How to bypass the restriction (methods vary depending on the manufacturer):

Smartphone brand	Method of disabling EU Volume Cap	Risks
Samsung (One UI)	Enter in Phone code ##36446337##, select "Off" for the limitation.	May be reset after updating.
Xiaomi/Redmi/Poco (MIUI)	Set the region "India" in the system settings (Advanced → Region).	Some services (for example, Google Pay) may stop working.
Google Pixel	Disable in Settings → Sound → Security and notifications → Volume limit.	Requires Android 14+.

3. Resetting Bluetooth settings and profile conflicts

Android saves individual sound settings for each connected one. devices - it's called Bluetooth profile. Sometimes these profiles become corrupted after a system update or connection failure, resulting in an artificial volume reduction. Typical symptoms:

• 🔄 The headphones sound fine on another device (for example, on an iPhone or PC).
• 🔇 The volume "jumps" when playing music.
• 📱 In the Bluetooth settings next to headphones display a warning icon.

How to reset the Bluetooth profile:

Remove the headphones from the list of connected devices|Restart your smartphone|Turn on airplane mode for 30 seconds|Connect the headphones again and check the volume-->

If resetting does not help, try change Bluetooth codec priority:

1. Install the application Developer Options (or activate developer mode by clicking 7 times on the build number in Settings → About phone).
2. Go to Settings → System → Developer Mode → Bluetooth Settings.
3. Select AAC or aptX instead of SBC (default).

⚠️ Attention: On devices with a chip Qualcomm Snapdragon 8 Gen 2 (for example, OnePlus 11, Xiaomi 13 Pro), a forced codec change may cause crackling in the speakers. In this case, return the settings to SBC.

4. Headphone firmware update and manufacturer bugs. data-i="120">Manufacturers regularly release firmware updates for wireless headphones, but not all updates are tested for compatibility with Android. For example, after updating to version

Manufacturers regularly release firmware updates for wireless headphones, but not all updates are tested for compatibility with Android. For example, after updating to version 4.5.2 at Sony WF-1000XM4 many users complained about a decrease in volume by 30-40%. firmware JBL Live Pro 2 after flashing 1.4.0.

How to check and roll back the firmware:

• 📋 For Sony: use the application Sony | Headphones Connect, section "System information".
• 📋 For JBL/Bose: check in JBL App or Bose Music.
• 📋 For AirPods: connect to iPhone and check c Settings → Bluetooth → i (next to AirPods).

If the problem appeared after the update, try:

1. Reset the headphones to factory settings (usually by holding down the power button for 10-15 seconds).
2. Disable automatic firmware update in the companion application.
3. Contact manufacturer support with a rollback request (for example, Sony sometimes provides old firmware versions upon request).

List of headphones with known problems after updates

Sony WH-1000XM5 (firmware 1.5.1 - decrease in volume at low frequencies)
Nothing Ear (2) (firmware 1.1.0 - maximum limit to 80%)
Soundcore Space A40 (firmware 0.9.4 - sound distortion at volume >60%)

5. Hardware limitations: Bluetooth chip and interference

The volume of wireless headphones is affected not only by the software, but also by hardware features the smartphone. For example, devices with a chip Qualcomm WCN6855 (used in Samsung Galaxy S22, Google Pixel 7) have a limitation on the power of the Bluetooth transmitter, which can reduce the volume by 10-15 dB.

Other hardware reasons:

• 📡 Interference from Wi-Fi: if the smartphone and headphones operate on the 2.4 Hzfrequency, the signal may be suppressed by the router. Solution - switch Wi-Fi to 5 Hz.
• 🔋 Weak headphone battery: when the discharge is below 20%, many models (for example, Jabra Elite 85t) automatically reduce volume.
• 🛠️ Damage to the Bluetooth antenna in the smartphone (often after falls). Diagnosed at the service center.

How to check the power of the Bluetooth transmitter:

1. Install the application Bluetooth Auto Connect or nRF Connect.
2. Connect headphones and check the signal level (RSSI). Normal: from -40 dBm to -70 dBm.
3. If RSSI < -80 dBm —the problem is in the hardware of the smartphone or headphones.

6. Sound uniformity settings and equalizers

Many users forget that system or third-party equalizers they can artificially reduce the volume at certain frequencies. For example, in Samsung the default mode is enabled Adaptive Sound, which analyzes the surrounding environment and adjusts the sound - sometimes too aggressively.

Where to look for settings:

• 🎛️ Samsung: Settings → Sound and vibration → Sound quality and effects → Adaptive sound.
• 🎛️ Xiaomi: Settings → Sound → Equalizer (turn off presets like "Voice" or "Bass").
• 🎛️ Google Pixel: Settings → Sound → Equalizer (reset to factory settings).

Also check third-party applications:

• 🎵 Poweramp, Musicolet — have built-in equalizers.
• 🎧 Wavelet, ViPER4Android — may conflict with system ones settings.
• 📱 Dolby Atmos (on Samsung, Lenovo) - sometimes resets the volume after updating.

7. Viruses, adware and sound "optimizers"

An unlikely but possible scenario: you have an application installed on your smartphone that Forcibly lowers the volume to display advertising or collect data. Such apps are disguised as:

• 🛡️ "Battery optimizers" (for example, Battery Doctor).
• 🎵 "Sound enhancers" (for example, Volume Booster GOODEV —some versions contain malicious code).
• 📊 "Health monitors" (for example, Hearing Testthat block volume above 80 dB).

How to check and remove:

1. Open Settings → Applications → Permissions → Microphone and check the list of apps with access.
2. Install Malwarebytes or Kaspersky and scan the system.
3. Check battery consumption: if unknown application consumes >5% in the background - remove it.

⚠️ Attention: Some "cleaners" (for example, CCleaner) may themselves be the source of problems. After removing them, you may need to reset the sound settings.

FAQ: Frequently asked questions about lowering the volume

Is it possible to physically increase the volume of the headphones if all the settings are checked?

Yes, but this requires disassembling the device. In some models (for example, JBL Tune 510BTyou can replace the speakers with more powerful ones or resolder the resistors on the amplifier board. However, this will void the warranty and may damage the headphones. An alternative is to use an external one. Bluetooth amplifier (for example, FiiO BTR5).

Why do the same headphones sound louder on iPhone than on Android?

Apple uses a proprietary codec AAC optimized for its devices, while Android often relies on SBC or LC3. In addition, iOS does not have strict restrictions on EU Volume Cap. To equalize the volume, try to force enable AAC in the developer settings on Android.

After the Android update, the headphones became quieter. How to roll back?

Rolling back the Android version is only possible on unlocked bootloaders. Instructions:

1. Download the firmware of the required version from the website XDA Developers or 4PDA.
2. Install ADB Tools and run the command:

   fastboot flash system system.img

3. Reset to factory settings (fastboot -w).

Attention: This will delete all data and may lead to a bricked device if the warranty is violated.

Does a case or protective glass affect the volume of wireless headphones?

Yes, but indirectly. Metal cases or cases with magnets can interfere with the Bluetooth signal, which leads to loss of data packets and, as a result, a decrease in volume. Try removing the case and testing. sound. Also avoid placing your smartphone in pockets with coins or keys.

Which headphones suffer least from volume problems on Android?

According to tests from 2026, models with support for aptX Adaptive i show the least problems with volume. data-i="232">(excellent compatibility with Android). LDAC:

• Sennheiser Momentum True Wireless 3 (excellent compatibility with Android).
• Technics EAH-AZ80 (uses LDAC without restrictions).
• 1More SonoFlow (budget model with aptX).

Avoid headphones with proprietary codecs (for example, Huawei FreeBuds often conflict with non-Huawei smartphones).
