How to fix it
Work through these in order, the most common causes come first.
Why Bluetooth Speakers Fail to Connect
Connection failures fall into three categories: the speaker is not discoverable (fixes 1 and 3), the pairing data is corrupted or outdated (fixes 2 and 6), and the signal cannot get through (fixes 4 and 5).
Work through them in order rather than jumping to a factory reset, since most problems resolve in the first three steps.
The speaker must be in pairing mode to appear in your phone's Bluetooth scan.
Most speakers reconnect to the last device automatically and do not advertise themselves to new devices unless forced.
Hold the Bluetooth button for 3 to 5 seconds until the LED flashes rapidly.

FAQ
Common questions
Why does my Bluetooth speaker keep disconnecting?
First, range: Bluetooth 5.0 has a theoretical range of 800 feet but real-world range in a home with walls and interference is 20 to 40 feet, and stepping behind a wall or moving the phone to another room can cause dropouts. Second, interference from other 2.4 GHz devices, particularly Wi-Fi routers and microwaves. Third, a low battery on either the speaker or the phone, since both reduce Bluetooth transmission power when battery-saving modes engage. Fourth, a firmware incompatibility between the phone OS version and the speaker firmware, which is resolved by updating both.
Can I connect two phones to one Bluetooth speaker at the same time?
Some speakers support multipoint Bluetooth, which allows two devices to be connected simultaneously so either can play audio without disconnecting the other. The Bose SoundLink Flex, JBL Charge 5, and several other current models support this. However, only one device can stream audio at a time; the other is connected but paused. To switch sources, pause on one phone and press play on the other. If the speaker does not support multipoint, connecting a second phone will either disconnect the first or fail to connect.
Why does my Bluetooth speaker sound choppy or stuttery?
Choppy audio is almost always an interference or range problem, not a speaker defect. Move the phone closer to the speaker and away from Wi-Fi routers and other 2.4 GHz devices. If the problem persists at close range, check whether the phone is running a CPU-intensive app or game that is starving the Bluetooth stack of processing time. Restarting both the phone and the speaker often resolves transient stuttering. If the problem is consistent and reproducible at close range with no interference, update firmware on both devices. Persistent stuttering after all troubleshooting points to a degrading Bluetooth antenna in the speaker, which is a hardware problem.
Why does my Bluetooth speaker have a delay between video and audio?
Bluetooth audio has inherent latency because the audio signal must be encoded, transmitted, and decoded. SBC codec latency is roughly 150 to 250 milliseconds, which is noticeable as a lip-sync delay during video. aptX Low Latency reduces this to roughly 40 milliseconds, which is imperceptible, but very few portable speakers support it. The practical fix is to use the video app's audio sync or delay adjustment if available, or to accept that Bluetooth speakers are not ideal for video watching w here lip sync matters. For gaming and video, a wired speaker or headphone connection eliminates the delay entirely.
