The brand's wireless headphones Hoco have gained popularity due to their affordable price and decent sound quality, but the process of their initial setup on smartphones running Android sometimes raises questions among users. Unlike some premium ecosystems, where devices find each other instantly, this requires manual intervention in the Bluetooth system. An incorrect sequence of actions often leads to the fact that the gadget does not see the accessory or connects to only one earphone from a pair.
In this article we will analyze in detail the algorithm of actions necessary for successful pairing, and also touch on the nuances of setting up the sound profile and controlling gestures. You will learn how to put your device into search mode, what to do if channels are out of sync, and how to optimize codecs for better sound. Following these recommendations will help you avoid common mistakes when starting up for the first time.
Preparing the device for the first time
Before starting the pairing procedure, it is critical to make sure that both headphones have sufficient battery power. If the lights flash red or the device emits a low-battery signal, the pairing process may be interrupted midway, resulting in a software crash. Place the headset in the case and connect it to a power source for at least 30 minutes, even if the indicators show power.
The next step is to completely reset the previous settings if the headphones were previously used with another phone. The Bluetooth protocol remembers the last active connection, and when you try to connect the device to a new smartphone, it may automatically try to find the old gadget instead of going into discovery mode. Delete the profile Hoco from the list of saved devices on all gadgets with which they previously worked.
⚠️ Attention: Do not remove the headphones from the case at the same time if the instructions for your specific model prescribe a different procedure. Some versions require removing first the left, then the right earphone to correctly initialize the master channel.
Make sure that geolocation is enabled on your smartphone. In modern versions of Android, location services are required for Bluetooth Low Energy (BLE) device scanning to work. Without an active GPS module, the phone may simply not display the headphones in the list of available devices for connection, even if they are in pairing mode.
Before connecting, restart your smartphone - this will clear the Bluetooth stack cache and eliminate possible software freezes in the device detection service.
Phone pairing algorithm
The connection process varies depending on the form factor of your headset: TWS in-ear or full-size model. For most TWS models Hoco you need to remove both headphones from the charging case at the same time. Once removed, they should automatically turn on and enter pairing mode, as indicated by the lights flashing quickly (usually white or blue-red).
If automatic entry into search mode does not occur, you will need to force activation. To do this, press the touchpads on both headphones at the same time and hold them for 5-7 seconds. Some models require you to hold the buttons longer until the indicators begin to flash at a different frequency. This is a signal that the device is ready to receive a command from the smartphone.
On the screen of your Android smartphone, go to the settings menu and select the section Connected devices or Bluetooth. Click the "Add New Device" or "Search" button. In the list that appears, find the name of your model, which usually contains a prefix Hoco and model index (for example, Hoco W40 or Hoco ES38). Click on the name to begin the pairing procedure.
- 🔵 Make sure that the headphones are no more than 1 meter away from the phone during the first pairing for a stable exchange of encryption keys.
- 🔵 If the phone asks for a PIN code when connecting, enter the standard combination
0000or1234, since most Hoco devices use these default values. - 🔵 After successful connection, the status in the menu will change to "Connected" for the "Multimedia" and "Call Sound" profile.
☑️ Checking success connections
Configuring audio codecs and sound quality
After a successful connection, the standard Android settings may not provide the maximum sound quality that your headset is capable of delivering. By default, the system often selects the SBC codec for maximum compatibility, but many models support more advanced compression algorithms such as AAC or aptX. Switching to a high-quality codec can significantly improve high-frequency detail and connection stability. Hoco support more advanced compression algorithms such as AAC or aptX. Switching to a quality codec can significantly improve high-frequency detail and connection stability.
To change these settings, you need to activate the developer menu on your smartphone. Go to Settings → About phone and quickly click 7 times on the “Build number” item. After a notification appears that you have become a developer, return to the main settings menu, find the section For developers and scroll down to the “Audio” block.
| Parameter | Description | Recommended value |
|---|---|---|
| Bluetooth Audio Codec | Audio stream compression algorithm | AAC or aptX (if supported) |
| Bits Per Audio Sample | Audio sample bit depth | 24 bit |
| Sample Rate | Sampling frequency | 48.0 kHz or 96.0 kHz |
| LDAC | High-quality codec Sony | Enabled (for Hi-Res audio) |
Changing these settings requires restarting the Bluetooth service or the smartphone itself. It is worth remembering that choosing a high bitrate codec (for example, LDAC) can increase the power consumption of both the smartphone and headphones, reducing battery life. Experimentally select a balance between sound quality and listening time that suits you.
Why can sound be distorted at high bitrates?
If you have selected the maximum quality settings, but are in an area with a large number of wireless networks (office, metro), the signal may be subject to interference. In such cases, the system will automatically lower the bitrate or revert to SBC, which may cause short-term audio stuttering.
Touch and Gesture Calibration
Playback and calling functions are controlled via touch panels located on the headphone body. The brand’s gesture logic may differ from the standard one: a single touch is often responsible for a pause, a double touch for switching the track forward, and a triple touch for backward. However, the length of time you hold to activate the voice assistant or answer a call takes some getting used to. Hoco may differ from the standard one: a single tap is often responsible for pausing, a double tap for switching the track forward, and a triple tap for backwards. However, the length of the hold to activate the voice assistant or answer a call takes some getting used to.
If standard gestures do not work or are delayed, the problem may be that the touch is not registering correctly. Make sure the sensor surface is clean and dry and that you touch it with your fingertip and not your fingernail. In some cases, “training” the sensor is required: perform a series of 10–15 consecutive clicks at a rhythmic pace immediately after connection.
To fine-tune actions, you can use third-party applications from Google Play, such as Button Mapper or specialized utilities for managing Bluetooth devices. They allow you to reassign actions to long presses or combinations if the standard headphone firmware does not provide such flexibility. This is especially true for users who want to assign a call to a specific application to a long hold.
⚠️ Warning: Avoid pressing too hard on the touchpad. Mechanical pressure can damage the speaker membrane or displace the contact pads inside the housing, which will lead to complete failure of the sensor.
Solving problems with channel desynchronization
One of the most common problems of owners of TWS headsets is the situation when the sound is played in only one earphone, or the right and left channels work independently of each other (mono mode instead of stereo). This occurs due to a loss of synchronization between the headphones themselves, when they stop “seeing” each other and connect to the phone as two separate devices.
To resolve this problem, you must perform a Hard Reset procedure. The algorithm of actions is usually the following: place both headphones in the charging case, make sure that they start charging (the indicators light up). Then, without closing the lid, press the touch zones on both headphones at the same time and hold them for 15-20 seconds. The indicators should blink several times in a specific rhythm (for example, three times red), which signals that the pairing memory is being cleared.
After the reset, remove the device from the Bluetooth list on your smartphone, turn off Bluetooth on your phone and turn it on again. Take the headphones out of the case and wait until they synchronize with each other (usually one indicator stops blinking, and the second continues). Only after this start searching for the device on your phone. This sequence ensures that the phone will connect to the master earphone, which is already transmitting a signal to the slave.
- 🔵 Check the charging contacts in the case: if one earphone does not charge due to oxidation of the contacts, it will not be able to participate in the synchronization process.
- 🔵 Make sure that the same firmware version is installed on both headphones (relevant for new models with support for over-the-air updates).
- 🔵 If the problem recurs constantly, there may be a hardware defect in the antenna of one of the modules.
The main reason for desynchronization is the different charge levels of Bluetooth modules within the pair. Always store your headphones in a case to ensure they charge evenly.
Battery optimization and energy saving
Android aggressively optimizes background processes to save power, which can negatively affect the stability of the connection with wireless headphones. If the music stops when the screen is off or while using other applications, the system may be killing the audio stream. You need to add the Bluetooth service to the list of power saving exceptions.
Go to the battery settings of your smartphone, find the list of applications and services. Select the system application Bluetooth or Google Play Services (depending on the phone model) and set the operating mode to “No restrictions” or “Do not optimize”. This will prevent the system from turning off the radio module during idle moments, ensuring instant restoration of the connection when playback is resumed.
It is also worth paying attention to the “Adaptive Sound” or “Absolute Volume Level” function, which is found in the developer menu or special sound settings. Disabling absolute volume allows you to adjust the sound level independently on the phone and on the headphones, which in some cases prevents driver conflicts and reduces the load on the headset power controller.
⚠️ Attention: The battery and developer settings menu interfaces may differ depending on the manufacturer’s shell (MIUI, OneUI, ColorOS). If you do not find these items, check the official documentation for your version of Android.
Regularly cleaning the case contacts with an alcohol wipe will also help extend battery life. Poor contact leads to the fact that the headphones are not charged to 100%, which over time causes a “memory” effect in the batteries and reduces the actual operating time of the device on a single charge.
Frequently asked questions (FAQ)
Why does the phone see Hoco headphones, but does not connect?
Most often the problem lies in the fact that the headphones are already connected to another device nearby. Bluetooth protocol prioritizes the last active connection. Turn off Bluetooth on all other gadgets within range. Also try “Forget device” in the phone settings and repeat the pairing again.
Can I use only one Hoco earphone?
Yes, most modern models support mono mode. To do this, remove only one earphone from the case (usually the right one, which is the master device). If the sound comes in only one when using a pair, then desynchronization has occurred and a reset is required.
How to update the firmware of Hoco headphones?
The Hoco brand rarely releases separate applications for updating the firmware of its budget models. The update usually occurs automatically when you connect to a smartphone with a new version of Android, if such a function is provided by the manufacturer. There is no specialized software like Hoco Sound for mass models.
What to do if the case indicator does not light up?
Check the charging cable and power supply. Try a different USB cable. If the headphone indicators inside the case light up during installation, but the indicator of the case itself is silent, the case's power controller may have failed or its battery has completely degraded.
Why is the sound in the headphones quieter than on other devices?
Check if the “Absolute Volume” function is enabled in the developer menu (try switching it condition). Also make sure that the ear guards are not clogged with wax, which is a common cause of volume drops. In the phone's sound settings, check the equalizer - the sliders may be lowered.
