How to Connect Bluetooth Headphones to iPhone (Sony and Others)

To connect Bluetooth headphones to your iPhone, put the headphones in pairing mode, open Settings > Bluetooth, turn Bluetooth on, and tap the headphones' name when it appears. Confirm that the status changes to Connected, then play audio at a comfortable volume. The iPhone steps are similar across brands, but the button or charging-case action that starts pairing depends on the headphone model.

For Sony headphones, check the model number before following a button sequence. This guide includes separate examples for the older MDR-10RBT, the MDR-XB950BT, and the WH-CH520, plus steps for reconnecting and fixing missing or silent headphones.

In this guide

• Prepare the headphones and pair them in iPhone Settings.
• Use the correct Sony model's pairing controls.
• Verify audio and reconnect a saved headset.
• Fix missing devices, connection failures, and app problems.
• Understand forgetting, resetting, multipoint, and audio sharing.

Before you start

Pairing registers the headphones with the phone so they can recognize each other later. Connecting establishes the current wireless link. A headset can be saved in your device list while remaining disconnected.

Charge the headphones sufficiently and keep them near the iPhone. The Sony model manuals below specify about 1 meter, or 3 feet, during pairing. Apple's general guide gives about 33 feet, or 10 meters, as the required Bluetooth range, but moving close is a better first attempt than trying from across the room.

Find the headset's model number on its label, packaging, or manual. On earbuds, pairing may use the charging case or touch controls rather than a power button. A light that indicates power does not necessarily indicate pairing mode.

For Plantronics headsets, our model-specific pairing guide separates Voyager call-button controls from BackBeat power-button and earbud procedures.

These instructions use the current Settings > Bluetooth route in Apple's iPhone guide. Bluetooth is not inside General. You can pair an ordinary compatible headset in Settings without installing a companion app. Optional app features and supported models vary by manufacturer.

If the headphones usually connect to another phone, tablet, or computer, disconnect that connection temporarily before troubleshooting. Keep its saved pairing unless you deliberately need to remove it.

Pair Bluetooth headphones with your iPhone

1. Put the headphones in pairing or discovery mode using their manufacturer's instructions. Look for the specified flashing indicator or spoken pairing announcement. If they are already on, simply waiting may not make them discoverable.
2. Unlock your iPhone and open Settings. Tap Bluetooth to display the device list.
3. Turn Bluetooth on if it is off. Keep this settings screen open while the phone looks for nearby discoverable accessories.
4. Find the headphones' name in the available-device list, often under Other Devices, and tap it. Check the model name carefully when other Bluetooth devices are nearby.
5. If the iPhone asks for an accessory PIN or passcode, use the value in the headphone manual. Do not substitute your iPhone unlock code or guess a universal headphone PIN.
6. Wait for the headphones to appear as Connected in your saved device list. You may also hear a connection tone from the headset.
7. Open Music, Podcasts, or another audio app and play something quietly. Confirm that you hear it through the headphones rather than the iPhone speaker.

Apple's Bluetooth accessory guide documents this route. If the headphones have already been paired and appear under My Devices, tapping that saved name may reconnect them without starting a new pairing.

Sony pairing controls by model

The following sequences come from each model's Sony manual. Do not apply one model's timing or indicator pattern to every Sony headset.

MDR-10RBT

1. Keep the headphones close to the iPhone and press and hold the headset's POWER button for more than 7 seconds.
2. Release the button and confirm that the indicator flashes blue and red alternately. That is the pairing indication described in Sony's manual.
3. On the iPhone, open Settings > Bluetooth, enable Bluetooth, and tap MDR-10RBT when it appears.
4. If a passkey is requested, enter 0000, the value specified for this model. Check that the connection completes, then test audio.

If pairing does not finish within about 5 minutes, the headset cancels pairing mode and turns off. Start the pairing sequence again. Sony's MDR-10RBT iPhone pairing guide also explains that the headset stores up to eight paired devices; adding another replaces the record whose latest connection is oldest.

WH-CH520

1. For its first pairing after purchase, or after initialization has removed its pairing information, turn on the headset. It enters pairing mode automatically.
2. To pair a second or subsequent device, press and hold the Bluetooth button for about 5 seconds or more to enter pairing mode manually.
3. Look for the blue indicator repeatedly flashing twice in a row and listen for “Pairing.”
4. In Settings > Bluetooth on the iPhone, tap WH-CH520. If a passkey is requested, Sony specifies 0000. Listen for the connection notification and check the phone's connection status.

The WH-CH520 pairing manual gives a five-minute pairing timeout. It also distinguishes storing several pairings from playing music: the headphones play music from one paired device at a time.

MDR-XB950BT

For the first pairing when the headset has no pairing information, Sony specifies holding POWER for about 2 seconds while it is off; it then enters pairing mode automatically. For a second or later device, hold POWER for about 7 seconds. Confirm alternating blue and red flashes, then choose MDR-XB950BT in iPhone Bluetooth settings. Its documented passkey is 0000 if requested.

These details are in the MDR-XB950BT pairing guide. Other Sony models may use a different button, indicator, or charging-case procedure. Use their own manual if the model name differs.

Verify audio or fix a silent connection

If Settings says Connected but sound still comes from the phone, check the playback destination before forgetting the device.

1. Start an audio item in an app such as Music or Podcasts. Make sure playback is running rather than paused.
2. Open the app's audio output selector, often shown with an AirPlay-style icon. You can also change the playback destination from the Lock Screen or Control Center while audio plays.
3. Choose your Bluetooth headphones from the output list. If they are absent, return to Bluetooth settings and check that they are connected and powered on.
4. Increase the playback volume gently and confirm audio reaches the headset. Check headset volume controls too if your model provides them.

Apple's Bluetooth audio guide describes selecting the destination. Moving the headphones out of range can return the output to the iPhone.

You can also inspect Settings > Bluetooth > information button beside the headphones > Device Type and select Headphone where available. Apple documents device-type classification as a way to improve audio accuracy; it does not create a missing Bluetooth connection.

If the headphones connect and play but volume behaves unexpectedly, see how to change the headphone volume limit on iPhone. Keep hearing protection in mind. A volume limit does not explain a device missing from the pairing list, and raising volume repeatedly is not a fix for the wrong output destination. For the speaker limit and other causes of quiet sound, see how to increase the max volume on iPhone.

Reconnect headphones you have already paired

Normally you do not need to repeat initial pairing every time. Turn the headphones on, keep them near the phone, and check Settings > Bluetooth. If they are listed under My Devices as disconnected, tap their name.

For the MDR-10RBT, Sony's reconnection guide uses a roughly two-second POWER-button hold to turn it on. That is different from the longer hold used for pairing. If it does not connect automatically, select MDR-10RBT from the iPhone's saved devices.

A new iPhone is a new pairing destination even if the headphones worked with your previous phone. Put the headset back into discovery mode for the new phone. Transferring other phone data does not remove the need to check this connection.

If the headphones reconnect to a nearby laptop instead, disconnect them there and select them on the iPhone. For supported multipoint models, you may instead be managing two connections; see the distinction below.

If the headphones do not appear

Work through these checks in order:

1. Confirm the exact pairing indicator. A steady power light or normal connection flash can mean the headset is on but not discoverable. Repeat its documented pairing sequence.
2. Check power and distance. Charge the headphones, move them beside the iPhone, and turn the headset off and back on. For earbuds, also check their case charge and seating according to the model manual.
3. Restart discovery after a timeout. The Sony examples above cancel pairing after about five minutes. Re-enter pairing mode before scanning again.
4. Check the other device. Temporarily disconnect the headphones from a nearby phone or computer that may reconnect automatically. Do not delete every saved pairing as a first step.
5. Check the saved list. If the name is already under My Devices, try tapping it there. A saved device may not appear as a new item under Other Devices.

Apple's accessory troubleshooting guide recommends checking charge, proximity, discovery mode, and restarting the accessory. If it works with another device but not the iPhone, Apple also suggests unpairing from other devices and trying again. Save that more disruptive step until you have checked the connection and pairing mode.

Forget and pair again when needed

Forgetting removes the saved pairing, so you must pair the headphones again before normal reconnection can resume. Make sure you can identify the headset and know how to start its discovery mode first.

1. Open Settings > Bluetooth and locate the correct headphones under My Devices.
2. Tap the information button, shown as an i, beside their name.
3. Tap Forget This Device, then confirm Forget Device.
4. Put the headphones back in pairing mode with their model's instructions.
5. Select their name again in Bluetooth settings and complete any documented PIN prompt.
6. Confirm Connected and repeat the quiet audio test.

Forgetting a headset does not erase the iPhone's photos or other personal files. It differs from merely disconnecting for a short break. Our guide to forgetting a Bluetooth device on iPhone explains those choices.

If you only want sound to return to the iPhone temporarily, select the phone as the playback destination or turn the headset off. The Bluetooth control in Control Center can temporarily disconnect accessories without deleting their pairings; use Settings when you need to inspect or remove a specific record.

App problems, interference, and further help

If a companion app cannot see headphones that already connect in Settings, check Settings > Privacy & Security > Bluetooth for that app's Bluetooth permission. This is an app-access control, separate from the main Bluetooth switch. Use the app supported by your exact headphone model; an unrelated Sony audio app is not a universal pairing requirement.

For dropouts or interference, first move the phone and headphones closer or try another position. Apple's guide notes that Airplane Mode may reduce audio interference, but it also interrupts cellular connectivity. It is an optional diagnostic step when that interruption is acceptable, not a requirement for normal pairing. Check that Bluetooth remains enabled if you try it, and turn Airplane Mode off afterward.

If Bluetooth is grayed out, cannot be enabled, or no accessories connect, Apple's troubleshooting guide directs you to Apple Support. If only this headset fails, ask its manufacturer to confirm compatibility and the correct recovery procedure for the model.

Resetting is different from initializing

Do not start with a factory initialization. It can erase the headset's saved pairings and require setup again. Check the model's manual for the difference between a reset and an initialization.

For example, Sony's WH-CH520 reset instructions retain pairing information and other settings. They are intended for a headset that cannot turn on or operate correctly: connect it to power using the supplied USB-C cable and a USB AC adapter, then press its volume + and volume – buttons simultaneously. Other models use different controls. Follow that model-specific procedure before considering its factory initialization instructions.

Frequently asked questions

Can one Sony headset connect to two devices?

Some models support multipoint, meaning one headset can maintain connections with two source devices. This is different from two headsets receiving audio from one iPhone. Pairing records alone do not establish multipoint support, and a Bluetooth version number is not enough to confirm it.

For the WH-CH520, Sony's model-specific multipoint guide describes enabling Connect to 2 devices simultaneously in the supported companion app after pairing both sources. To hear music from the second source, stop playback on the first and start it on the second. You do not hear two music streams mixed together. Check your own model's guide because other headsets have different limits.

Can two Sony headphones play the same iPhone audio together?

Pairing both headphones does not automatically make the iPhone send the same audio to both. Apple's Share Audio feature requires compatible AirPods or Beats and a supported iPhone or iPad. It is not the standard method for two Sony headsets.

External dual-headphone transmitters are a separate setup with their own input, adapter, and compatibility requirements. Do not treat enabling multipoint on a headset as a substitute for audio sharing.

Can I tap the iPhone on the headset's NFC logo instead?

Use the documented Bluetooth pairing steps for initial setup. An NFC shortcut discussed online may change the playback destination for an accessory that is already paired or connected; that is a different task. It does not resolve the prerequisite of headphones that never appear in the Bluetooth list, and behavior depends on the headset and phone.

Why does the headset request a PIN?

Some accessories require a passkey during registration. The Sony models documented above specify 0000, but another brand or model can differ. Consult its manual rather than trying several generic codes.

Will I need to pair again after repair or initialization?

You may need to pair again if either device loses the saved record. Sony's example manuals list initialization, repair-related removal, deletion on the phone, and overwriting an old record after the pairing limit as reasons. Check both the saved phone entry and the headset's pairing mode.

Start with the correct pairing indication, select the exact headphone name, and verify a quiet audio sample. That sequence lets you separate a missing Bluetooth link from an audio-routing or volume problem.
