How do I stream music through Bluetooth on my Android phone?

What is Bluetooth?

Bluetooth is a short-range wireless technology standard that allows devices to communicate within close proximity without the need for cables or wires (Bluetooth Technology Overview, https://www.bluetooth.com/learn-about-bluetooth/tech-overview/). It is commonly used for transferring data like audio streams between compatible devices that are typically within 10-100 meters of each other.

Bluetooth technology operates in the 2.4 GHz radio frequency band and uses frequency hopping spread spectrum (FHSS) to transmit data over 79 designated channels. It relies on short-range radio waves to connect devices, allowing for data exchange once a pairing process has been established between two compatible Bluetooth gadgets (Understanding Bluetooth Technology, https://www.cisa.gov/news-events/news/understanding-bluetooth-technology).

Bluetooth technology is available on most modern smartphones, tablets, computers, speakers and other gadgets. It offers wireless connectivity and collaboration between devices without the need for cables. This makes it useful for applications like streaming audio from a phone to a wireless speaker or headset.

Next, turn on your Bluetooth device like headphones or speaker and put it into pairing mode, which is usually done by pressing and holding a button on the device. Refer to the instructions that came with your device to find out how to put it into pairing mode.

Once your Bluetooth device is in pairing mode, it should show up in the list of available devices on your Android phone’s Bluetooth settings screen. Tap on the name of your device to initiate pairing. Your phone may automatically pair without needing further confirmation, or you may get a prompt to confirm pairing on one or both devices.

Once successfully paired, your phone will remember that Bluetooth device. The next time you turn the device on, it should automatically reconnect to your phone.

If you have trouble pairing, try turning Bluetooth off and back on again on both devices. Make sure the device is in proper pairing mode and that Bluetooth visibility is enabled on your phone during the process.

Stream Audio Over Bluetooth

Once your Android phone and Bluetooth device are successfully paired, you can start streaming audio over Bluetooth. Simply open your preferred music app on your Android phone and begin playing a song. Then in your music app’s audio settings, select the paired Bluetooth device as your audio output option. The music playback will automatically switch from your phone’s speakers to playing through your connected Bluetooth device like a wireless speaker or car stereo.

Most music apps have a dedicated button or option to select Bluetooth as the audio output. For example, in the Spotify app you can tap the Devices Available button in the player screen and select your paired Bluetooth device. In YouTube Music, tap the Cast button and select your Bluetooth device. This enables the audio to be streamed from your Android phone to the Bluetooth device so you can hear the music play from its speakers.

Bluetooth audio streaming allows you to play music wirelessly from your phone to any connected Bluetooth device within range. Just keep the phone and Bluetooth device paired and within close proximity, open a music app on your Android phone, and select the Bluetooth option for seamless wireless audio streaming.

Adjust Bluetooth Audio Settings

Some Android devices allow you to change Bluetooth audio quality in the Advanced Bluetooth options. This allows you to select different Bluetooth audio codecs like SBC, AAC, aptX, aptX HD or LDAC if supported by your phone and Bluetooth device.

To access advanced Bluetooth settings on Android:

Open Settings app
Go to Connected Devices > Connection Preferences > Advanced

Under Audio Codec, select your preferred codec like AAC or aptX HD

Higher quality codecs like aptX HD can provide better audio quality over Bluetooth but use more bandwidth. The optimal codec will depend on your specific phone and headphones/speakers.

You may also be able to adjust EQ settings and presets on the connected Bluetooth device itself using its companion app. This allows you to customize the sound profile to your liking.

Troubleshooting Bluetooth Streaming

Bluetooth streaming can sometimes have issues connecting and maintaining a stable audio connection. There are a few basic steps to troubleshoot and restore smooth Bluetooth streaming between your Android device and a speaker, car, or other accessory:

First, make sure your Android phone and the Bluetooth device are within 30 feet of each other. Bluetooth has a limited range, so moving closer may help connectivity. If you’re in a car, try placing your phone in a cup holder near the center console.

You may need to re-pair your devices if the connection is spotty. Go into your Bluetooth settings on both devices and “forget” or “unpair” them. Then restart your phone and speaker and pair them together again [1].

Other wireless interference can disrupt Bluetooth signals. Make sure WiFi, mobile data, microwaves, cordless phones, and other devices aren’t causing excessive interference. Turn some of these off or move your Android phone away from sources of interference.

Check for software updates that could improve connectivity. Lowering streaming quality settings may also help. As a last resort, reset your phone’s Bluetooth drivers and network settings. With some tweaking and troubleshooting, you can restore smooth audio streaming over Bluetooth.

Bluetooth Streaming Alternatives

While Bluetooth is convenient for wireless streaming, it’s not the only option for streaming music from your Android device. Here are some alternatives to consider:

You can stream music over your WiFi network using DLNA or Chromecast. Many Android devices and apps support DLNA, which allows you to stream media between compatible devices on the same WiFi network. Or you can use a Chromecast device plugged into a speaker or TV to stream music from your Android phone.

You can also use an audio cable to connect your Android device to headphones, speakers, your car stereo, or other devices. This avoids relying on wireless streaming entirely. You’ll need an adapter or dongle like a USB-C to 3.5mm headphone jack adapter for newer Android phones without a headphone jack. But streaming over a direct wired connection can provide higher quality audio without any wireless interference.

So if you’re having issues with Bluetooth streaming, need better audio quality, or want to conserve battery life, consider streaming your music library and apps over WiFi or using a wired audio connection instead.
