Most phones send Bluetooth audio to only one device at a time, so to use two headphones you need a phone that supports dual audio, such as many Samsung Galaxy models, Apple's Share Audio feature for iPhone with AirPods or Beats, a newer phone with LE Audio and Auracast, or an external Bluetooth transmitter that broadcasts to two sets at once.
Why this happens
Standard Bluetooth music streaming (A2DP) was designed as a one-to-one link, so a phone normally pairs its audio with a single output. Playing to two headphones needs an extra feature or a hardware workaround.
- Samsung and some other Android phones add a Dual Audio feature that sends to two Bluetooth devices.
- iPhone supports Share Audio, but only with two sets of AirPods or supported Beats headphones.
- Newer phones and headphones with Bluetooth LE Audio and Auracast can broadcast to many receivers, though support is still spreading.
- An external Bluetooth transmitter with two-device pairing can serve any headphones, regardless of phone brand.
Is this normal?
It is normal that a plain phone connects to only one at a time. Sharing to two is a special feature, so whether it works depends entirely on your specific phone and headphones.
Does it cause any problems?
No harm to the devices. The trade-offs are that volume and audio sync between the two headphones can differ slightly, and dual streaming uses more battery.
How to fix or check it
- On a Samsung Galaxy phone, pair both headphones, then open Settings, Connections, Bluetooth. Look under the three-dot menu or Advanced settings for Dual Audio and enable it, or simply connect both from the list on newer models.
- On iPhone, connect the first AirPods or Beats, open Control Center, tap the audio card, tap Share Audio, then bring the second supported pair close and follow the prompt.
- On a phone with LE Audio and Auracast, use the Auracast or audio-sharing menu and have both headphones join the broadcast. Check that both devices list Auracast support.
- For any phone, plug a Bluetooth transmitter into the headphone jack or USB-C port, set it to dual or multi-point mode, and pair both headphones to the transmitter.
- Test playback and adjust volume on each headphone separately, since each may have its own level.
Frequently asked questions
Can any two headphones be used together?
With phone features like Dual Audio or Share Audio, the headphones often must meet brand or profile requirements. An external transmitter is the most universal option.
Will the sound stay in sync?
Usually close enough for music and video, but tiny timing or volume differences between the two headphones are possible.
Does the iPhone Share Audio work with non-Apple headphones?
No. Share Audio is limited to AirPods and supported Beats models. For other headphones use a transmitter instead.
